## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 51/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (delete_alert).
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 67/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 12940 tokens (~157/item across 82 items; 82 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 50/100
  - Stability observed for 15 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 88/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - 1 of 2 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "check_programmable_transfer" implies "transfer" and declares readOnlyHint instead, contradicting what its own name says it does.
  - An AI judge read all 83 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (82)

### `search` (~127 tokens)

Search Cardano entities

Find a Cardano token, liquidity pool, NFT collection, stake pool, ADA Handle, address, transaction, block or epoch by name, ticker or identifier. Use this first whenever you have a name or ticker rather than an exact id: each result names the tool to call next and the id to pass. Stake amounts in results are whole ADA.

Input parameters:

- `limit` (integer): How many results to return (1-20, default 8).
- `query` (string, required): Name, ticker, `$handle`, address, pool id, policy id, transaction hash, block height or epoch number.

### `list_tokens` (~475 tokens)

Rank Cardano tokens

Ranked list of Cardano native tokens traded on DEXes, for questions such as "top tokens", "biggest gainers today", "trending now" or "new pairs". Prices are in ADA and USD, volume and liquidity in ADA (24 h), market cap in USD, changes in percent. `rank` (default) combines market cap with pool liquidity and is the best general ordering; `volume` is what the site calls Trending. The answer names the floors it applied (`minLiquidityAda`, `minHolders`).

Input parameters:

- `hideHighRisk` (boolean): Leave out tokens the safety screen rates as high risk.
- `limit` (integer): How many tokens to return (1-50, default 10).
- `minHolders` (integer): Leave out tokens known to have fewer holders than this. Replaces the default floor of the ordering (100 for mcap and fdv); 0 = none.
- `minLiquidityAda` (number): Leave out tokens with less pool liquidity than this many ADA (both sides of the pools). Replaces the default floor of the ordering; 0 = none.
- `order` (string): Direction. Default: descending (age: ascending, youngest first). Ignored by rank, trending, new, gainers and losers.
- `page` (integer): Page number, from 1.
- `period` (string): Window of the volume, txns, change, gainers and losers orderings.
- `query` (string): Only tokens whose ticker, name or unit starts with this text.
- `sort` (string): Ordering. volume = traded volume over `period` (the site's Trending list); gainers/losers/change use the change of the USD price over `period` (24 h: change24hPct; change24hAdaPct is the change of th…

### `get_token` (~165 tokens)

Token detail

Everything about one Cardano token: price (ADA and USD), the change of each of the two prices over 5 m to 7 d (percent; they differ by the move of ADA/USD), 24 h volume and liquidity (ADA), market cap and FDV (USD), supply, holder count, evidence-based fraud flags (open mint authority, concentrated supply, liquidity pulled, creator sold, lookalike, new and thin: each with its evidence and rule), its largest liquidity pools and a safety assessment. Use it to answer price, liquidity or risk questions about a specific token.

Input parameters:

- `unit` (string, required): Token unit: 56-hex policy id followed by the asset name in hex (no separator). Get it from `search` or `list_tokens`.

### `get_token_candles` (~183 tokens)

Token price candles (OHLCV)

Open/high/low/close price candles and traded volume for a token, newest last, for charts, trend and volatility questions. Prices are per token in ADA (default) or USD; volume is in ADA. Returns compact rows: [time ISO, open, high, low, close, volumeAda, trades].

Input parameters:

- `allPools` (boolean): true aggregates every pool of the token (volume-weighted price, summed volume); false uses its primary pool.
- `interval` (string): Candle width.
- `limit` (integer): How many most recent candles to return (1-500, default 100).
- `quote` (string): Currency of the prices.
- `unit` (string, required): Token unit: 56-hex policy id followed by the asset name in hex (no separator). Get it from `search` or `list_tokens`.

### `get_pool` (~88 tokens)

Liquidity pool detail

One DEX liquidity pool: DEX, token pair, reserves (decimal-adjusted token amounts), TVL and 24 h volume (ADA), price (quote token per base token), fee (percent) and last update. Pool ids come from `get_token` (its `pools`) or `search`.

Input parameters:

- `poolId` (integer, required): Realtap pool id (a positive integer).

### `get_recent_trades` (~196 tokens)

Recent DEX trades

Latest DEX swaps, newest first, for exactly one of: a token (`unit`), a pool (`poolId`) or a wallet (`address`). Each trade has the time, DEX, side (buy/sell of the base token), amounts in and out (decimal-adjusted), price in ADA, value in ADA and USD, the trader's stake address and the transaction hash.

Input parameters:

- `address` (string): Wallet (addr1…, stake1… or $handle): trades made by this wallet.
- `cursor` (string): Value of `nextCursor` from the previous call, to get the next page.
- `limit` (integer): How many trades to return (1-50, default 10).

- `unit` (string): Token unit: trades of this token. Give exactly one of unit, poolId, address.

### `get_market_overview` (~97 tokens)

Cardano DEX market overview

Snapshot of the whole Cardano DEX market: ADA price (USD), 24 h volume and total value locked (ADA and USD), trade count, volume share per DEX (percent), and the top gainers, losers and trending (most traded by 24 h volume) tokens. Use it for "how is the Cardano market doing" questions and to check how fresh the data is (`sync.lagSeconds`).

### `get_market_history` (~245 tokens)

DEX market over time

The Cardano DEX market over a timeframe, per day (per week over a year, per month beyond two years): volume in ADA, settled swaps, makers (distinct trading wallets per day) and trading fees (volume times pool fee), for all DEXes together or one DEX. Returns the totals of the full UTC days of the range, their change against the equally long period before (null when that period is not stored), each period, and the DEXes of the range by volume with their share. The running day and the day our history starts on are marked partial and left out of totals; `coverage` says which days are counted and where history starts. Use it for "how much traded on Cardano last month", "is volume growing", "market share of Minswap over 90 days".

Input parameters:

- `dex` (string): One DEX by its name as `list_dexes` returns it (for example MinswapV2). Leave out for all DEXes together.
- `range` (string): Timeframe: the last 7, 30, 90 or 365 full days, or everything stored.

### `list_dexes` (~134 tokens)

Cardano DEXes compared

Every Cardano DEX the site indexes, side by side: volume, swaps, makers (distinct wallets) and trading fees of the last 24 hours with the share of all volume, the same over the last 7 and 30 full days where that many are stored, liquidity (ADA in its pools), number of pools and fee APR (trading fees of 7 full days scaled to a year, over the liquidity in pools that have liquidity providers; null for bonding curves, order books and pools whose fee is unknown). DEX versions are separate entries (Minswap and MinswapV2).

### `list_market_trades` (~230 tokens)

Trades on all DEXes, large trades

Settled swaps on every Cardano DEX, newest first, optionally only those of at least `minAda` ADA ("large trades", "whale trades") or on one DEX. `window` is how far back to look (default 24 hours). Each trade has the time, DEX, the token traded (see `tokenUnits` for units), amounts, price and value in ADA and USD, the trader's stake address, the app that built the order and the transaction hash. For the trades of one token, pool or wallet use `get_recent_trades`.

Input parameters:

- `cursor` (string): Value of `nextCursor` from the previous call, to get the next page.
- `dex` (string): Only this DEX, by its name as `list_dexes` returns it.
- `limit` (integer): How many trades to return (1-50, default 10).
- `minAda` (number): Only trades worth at least this many ADA (for example 10000).
- `window` (string): How far back to look.

### `get_wallet` (~117 tokens)

Wallet balances

Current holdings of a Cardano wallet: ADA balance, native tokens with balances (decimal-adjusted) and their value in ADA and USD, total portfolio value and trades in the last 24 h. Accepts a payment address (addr1…), a stake address (stake1…, all its addresses combined) or an ADA Handle ($name).

Input parameters:

- `address` (string, required): addr1…, stake1… or $handle.
- `limit` (integer): How many positions, largest value first, to return (1-50, default 15).

### `get_wallet_pnl` (~128 tokens)

Wallet trading profit and loss

Realised and unrealised profit and loss of a wallet's DEX trading (FIFO, in ADA and USD), win rate (percent), trade count, volume (ADA) and the tokens that contributed most. Only covers swaps since `coverageFrom`. Slower than other tools and limited to fewer calls per minute: call it only when PnL is actually asked for.

Input parameters:

- `address` (string, required): addr1…, stake1… or $handle.
- `limit` (integer): How many tokens, largest PnL first, to return (1-30, default 10).

### `get_token_liquidity` (~234 tokens)

Token liquidity: depth and liquidity flow

Liquidity of one token. Depth: for each constant-product pool paired with ADA, the ADA that moves the pool's price 2 % up (buying) and the ADA received when selling moves it 2 % down, by the pool's own curve and fee (pools of other kinds, other pairings or without a fee are listed with the reason and left out of the sums). Flow: liquidity added and removed over the window (value of both sides in ADA at the pool price before each order settled; withdrawals are estimates from their LP share), net flow per wallet and the latest orders. Every figure carries what it covers: `coverage` names the window, the pools measured and the DEXes with no liquidity orders recorded.

Input parameters:

- `limit` (integer): How many wallets and orders to return (1-25, default 10).
- `unit` (string, required): Token unit: 56-hex policy id followed by the asset name in hex (no separator). Get it from `search` or `list_tokens`.
- `window` (string): How far back the flow figures look.

### `get_token_distribution` (~160 tokens)

Token holder distribution

How a token's supply is spread over its holders: share held by the top 10, 50 and 100 holders, holders by size, the rest of the supply, balances sitting in DEX pools and contracts. `coverage` says exactly what the list is: the largest balances of a complete read, or only the largest among the addresses read before the read stopped (then no "top N" share is given, and the holder count is a lower bound). Never quote a share as "top N" when `coverage.listIsTop` is false.

Input parameters:

- `unit` (string, required): Token unit: 56-hex policy id followed by the asset name in hex (no separator). Get it from `search` or `list_tokens`.

### `get_wallet_activity` (~132 tokens)

Wallet trading hours and liquidity history

When a wallet trades: settled DEX swaps by weekday and hour (UTC) over the swaps the site holds (`from`, `to` say which span; a very busy wallet is cut to its newest 10,000), the busiest hour, and the liquidity the wallet added and removed by pool (executed orders only; value in ADA at the pool price of the moment). Wallets without a stake key cannot be counted.

Input parameters:

- `address` (string, required): addr1…, stake1… or $handle.
- `limit` (integer): How many pools to return (1-25, default 10).

### `get_swap_quote` (~172 tokens)

Swap quote (no trade is made)

Estimate what a swap would return right now: the best route across the indexed DEX pools, amount out (decimal-adjusted), effective price, price impact (percent) and the smallest pool liquidity on the route (ADA). It never builds, signs or submits a transaction: the result includes `swapUrl`, a link the user opens to review the trade and sign it in their own wallet.

Input parameters:

- `amount` (number, required): Amount of tokenIn to sell, decimal-adjusted (100 = 100 ADA when tokenIn is ADA).
- `tokenIn` (string, required): What is sold: a token unit, or "lovelace" / "ADA" for ADA.
- `tokenOut` (string, required): What is bought: a token unit, or "lovelace" / "ADA" for ADA.

### `plan_swap` (~291 tokens)

Swap plan with every fee (no trade is made)

Plan a swap the way Realtap's own router places it: one order, or the amount split over several pools of Minswap V2, SundaeSwap V3 and WingRiders V2, with the expected and the minimum amount received at the given slippage, every fee in ADA (DEX batcher fees, interface fee, network fee), the refundable deposit, the price impact (percent) and the result net of fees. More exact than `get_swap_quote` (integer pool maths, fees included) but limited to those three DEXes. Nothing is built or signed: a person executes the plan at `swapUrl`; an agent that signs with its own key calls `build_swap_transaction`.

Input parameters:

- `amount` (number, required): Amount of tokenIn to sell, decimal-adjusted (100 = 100 ADA when tokenIn is ADA).
- `maxOrders` (integer): Most orders the amount may be split over (1 = a single order).
- `slippagePct` (number): How far the price may move against the trade before an order must not execute, in percent (1 = 1 %).
- `tokenIn` (string, required): What is sold: a token unit, or "lovelace" / "ADA" for ADA.
- `tokenOut` (string, required): What is bought: a token unit, or "lovelace" / "ADA" for ADA.

### `build_swap_transaction` (~361 tokens)

Unsigned swap transaction (nothing is signed or sent)

Build an unsigned Cardano swap transaction for a wallet that signs for itself, through the DexHunter aggregator. Returns the transaction as CBOR hex with its hash, what it does (network fee, validity, every output with address, ADA and tokens, and which outputs return to the wallet), the expected and the minimum amount received, the fees (DEX batcher, aggregator and partner fee, network fee, all in ADA), what the trade costs worked out from the transaction itself next to what the aggregator states (`cost`, with a warning when the transaction takes more), and the steps to sign and submit it. Fees are fixed ADA amounts, so a small trade can cost a large share of itself. Realtap never signs, holds keys or submits: nothing happens until the owner of `address` signs the transaction and sends it. Call it only when that owner asked for this trade, and check the token with `get_token` first (liquidity, safety). Limited to a few calls per minute.

Input parameters:

- `address` (string, required): Mainnet payment address (addr1…) of the wallet that will sign: its UTxOs are spent and it receives the result.
- `amount` (number, required): Amount of tokenIn to sell, decimal-adjusted (100 = 100 ADA when tokenIn is ADA).
- `slippagePct` (number): How far the price may move against the trade before the order must not execute, in percent (1 = 1 %).
- `tokenIn` (string, required): What is sold: a token unit, or "lovelace" / "ADA" for ADA.
- `tokenOut` (string, required): What is bought: a token unit, or "lovelace" / "ADA" for ADA.

### `get_swap_status` (~108 tokens)

Status of a swap transaction

What became of a swap transaction: whether it is on chain and, for every DEX order it placed, whether the order is pending (waiting for the DEX batcher), complete (with the amount received and the settling transaction) or cancelled, plus the app or aggregator that placed it when known. Use it after a swap was submitted; orders normally settle within one to five minutes.

Input parameters:

- `txHash` (string, required): Hash of the transaction that placed the order: 64 hex characters.

### `list_open_orders` (~104 tokens)

Open swap orders of a wallet

Swap orders of a wallet that are still waiting at Minswap V2, SundaeSwap V3 or WingRiders V2 (unspent in the ledger right now), whichever app placed them: DEX, pool, amount sold, minimum to receive and when it was placed. Orders waiting at other DEXes are not listed; follow those with `get_swap_status`.

Input parameters:

- `address` (string, required): Mainnet payment address (addr1…) of the wallet.

### `list_nft_collections` (~121 tokens)

Rank NFT collections

Ranked list of Cardano NFT collections with floor price (ADA and USD), 24 h floor change (percent), volume (ADA, 24 h and 7 d), sales, listings, supply and holders. Use it for "top NFT collections" questions or to find a collection by name.

Input parameters:

- `limit` (integer): How many collections to return (1-50, default 10).
- `query` (string): Only collections whose name contains this text, or whose policy id starts with it.
- `sort` (string): Ordering.

### `get_nft_collection` (~98 tokens)

NFT collection detail

Market data for one NFT collection: floor price (ADA and USD) and its 24 h change (percent), volume (ADA) over 24 h, 7 d, 30 d and all time, sales counts, active listings, supply, holders and the most recent sales.

Input parameters:

- `policyId` (string, required): NFT policy id: 56 hex characters. Get it from `search` or `list_nft_collections`.

### `get_nft_listings` (~147 tokens)

NFTs for sale in a collection

Active marketplace listings of an NFT collection: asset name, price (ADA), marketplace, rarity rank when known, seller and listing time. Use it to find the cheapest or rarest NFTs currently for sale.

Input parameters:

- `cursor` (string): Value of `nextCursor` from the previous call, to get the next page.
- `limit` (integer): How many listings to return (1-50, default 10).
- `policyId` (string, required): NFT policy id: 56 hex characters. Get it from `search` or `list_nft_collections`.
- `sort` (string): price = cheapest first, recent = newest first, rarity = rarest first.

### `get_nft_depth` (~173 tokens)

NFT collection listing depth

What it costs to buy the cheapest N listings of an NFT collection and what the floor is afterwards: for 1, 2, 3, 5, 10, 25, 50, 100 and 250 listings the cost (ADA), the number of NFTs and the floor after buying them, plus the cost to buy everything priced up to 1.1x, 1.25x, 1.5x and 2x the floor. List prices as on the marketplace; read from the open listings this site has read, right now (a marketplace can show more). Use it to judge how thin a floor is.

Input parameters:

- `policyId` (string, required): NFT policy id: 56 hex characters. Get it from `search` or `list_nft_collections`.

### `get_nft_analytics` (~160 tokens)

NFT collection activity analytics

Trading analytics of one NFT collection over the last 7, 30, 90 or 365 days: sales, volume (ADA), distinct buyers and sellers per day and in total, creator royalties paid (only over sales whose royalty is recorded, with the coverage), volume by wallet size (wallets grouped by how many NFTs they bought or sold in the window) and the top traders. Sales whose buyer and seller are the same wallet are left out and counted in `excluded`.

Input parameters:

- `days` (integer): Window in days: 7, 30, 90 or 365.
- `policyId` (string, required): NFT policy id: 56 hex characters. Get it from `search` or `list_nft_collections`.

### `get_nft_trait_prices` (~173 tokens)

NFT trait prices

Per trait value of an NFT collection: how many assets have it, how many are listed and the cheapest listing (floor, ADA), and the sales in the window with their average and highest price. Only assets whose traits have been read are included; the answer says how many of the collection that is (`coverage`). Use it to price a trait.

Input parameters:

- `days` (integer): Window for the sales in days: 7, 30, 90 or 365.
- `limit` (integer): How many trait values to return (1-100, default 25).

### `get_nft_market` (~121 tokens)

Whole NFT market overview

The whole Cardano NFT market over the last 7, 30, 90 or 365 days: sales, volume (ADA), active buyers and sellers (distinct wallets over the window where it can be counted, else the daily average), and for each marketplace its volume, share, marketplace fees and creator royalties (over the sales whose split is recorded, with the coverage). Sales whose buyer and seller are the same wallet are left out.

Input parameters:

- `days` (integer): Window in days: 7, 30, 90 or 365.

### `get_nft_wallet_trades` (~112 tokens)

A wallet's trades in an NFT collection

The entries (purchases) and exits (sales) of one wallet in one NFT collection: asset, price (ADA), time and transaction. Entries are found by the wallet's stake key, exits through the listings it made; the answer says what it does not cover.

Input parameters:

- `address` (string, required): addr1… or stake1… address.
- `policyId` (string, required): NFT policy id: 56 hex characters. Get it from `search` or `list_nft_collections`.

### `list_stake_pools` (~236 tokens)

Rank stake pools

Ranked list of Cardano stake pools with ticker, live stake (ADA), saturation (percent), margin (percent), fixed cost (ADA per epoch), pledge (ADA), delegators, blocks this epoch, estimated yearly return at 100 % luck (percent) and, over its recent finished epochs, luck (blocks minted / blocks expected, percent) and the yearly return delegators got. Use it to compare pools or to find one by ticker or name.

Input parameters:

- `limit` (integer): How many pools to return (1-50, default 10).
- `maxMarginPct` (number): Only pools with a margin of at most this percent.
- `maxSaturationPct` (number): Only pools at most this percent saturated (100 = full).
- `query` (string): Ticker prefix, part of the name, or the start of a pool id.

### `get_stake_pool` (~198 tokens)

Stake pool detail

One Cardano stake pool: name, ticker, status, margin (percent), fixed cost and pledge (ADA), live and active stake (ADA), saturation (percent), delegators, blocks minted, estimated and recently realised yearly return (percent), description and homepage. `performance` lists its last finished epochs (blocks minted against blocks expected from its stake, luck in percent, the return delegators got) and says how many epochs are on record. Pass `stakeAda` to also get `rewardEstimate`: the ADA that amount is expected to earn per epoch and per year in this pool, with what the estimate assumes.

Input parameters:

- `poolId` (string, required): Bech32 pool id (pool1…) or its 56-hex form. Get it from `search` or `list_stake_pools`.
- `stakeAda` (number): Optional amount of ADA to delegate: adds an estimate of its staking reward in this pool.

### `compare_yields` (~254 tokens)

Compare where an asset can earn

Ranked comparison of the places ADA, a stablecoin or another Cardano token can earn a return, for a given amount: staking, lending pools (Liqwid, Lenfi), peer-to-peer loans (FluidTokens) and DEX liquidity pools. Each option carries the yearly rate (percent) and whether it is an APR (simple) or an APY (compounding included), what the rate was measured from and over which window, how much the venue holds, the lock-up, risk tags and the return after one year in units of the asset. Liquidity-pool rates are fee income before impermanent loss. `missingSources` names data this deployment could not read (those venues are absent, not zero) and `notCompared` the venues that are not indexed. Rates are current or past readings, not promises: say so when you quote them.

Input parameters:

- `amount` (number): How much of the asset, decimal-adjusted (1000 = 1,000 ADA when asset is ADA). A large amount lowers the rate of a small venue.
- `asset` (string): What is held: "ADA", or a token unit (policy id + asset name in hex) from `search`.

### `list_governance_actions` (~125 tokens)

Cardano governance actions

On-chain governance proposals (treasury withdrawals, parameter changes, hard forks, committee and constitution changes, info actions) with status, epochs, requested ADA and the current yes/no vote share (percent of voting power) of DReps and stake pools. Use it for questions about what Cardano is voting on.

Input parameters:

- `limit` (integer): How many actions, newest first, to return (1-30, default 10).
- `query` (string): Only actions whose title contains this text.
- `status` (string): active = open for voting now.

### `get_transaction` (~80 tokens)

Transaction detail

A Cardano transaction by hash: block, time, fee and total output (ADA), the net ADA and token change per address, minted or burned assets, certificates, withdrawals, and any DEX swaps or NFT sales it contains. Amounts are whole ADA and decimal-adjusted tokens.

Input parameters:

- `hash` (string, required): Transaction hash: 64 hex characters.

### `get_address` (~105 tokens)

Address or stake key on the explorer

Explorer view of a payment address (addr1…) or stake address (stake1…): type, whether it is a script, ADA balance, tokens held (decimal-adjusted, valued in ADA), the stake key, delegation and rewards (ADA) for stake addresses, and first/last activity. For portfolio value in USD use `get_wallet` instead.

Input parameters:

- `address` (string, required): addr1… or stake1… (resolve a $handle with `resolve_handle` first).

### `resolve_handle` (~88 tokens)

Resolve an ADA Handle

Resolve an ADA Handle ($name, or sub@root for subhandles) to the address that currently holds it, with its stake address and whether a script (for example a marketplace listing) holds it. Use it before sending-related answers or to turn a $handle into an address for other tools.

Input parameters:

- `handle` (string, required): Handle with or without the leading $, e.g. "$snek".

### `get_news` (~94 tokens)

Cardano news

Input parameters:

- `limit` (integer): How many articles to return (1-20, default 5).
- `query` (string): Only articles whose title or summary contains this text.

### `list_prediction_markets` (~255 tokens)

Prediction markets and their odds

Prediction markets on Cardano (Bodega Market), read from the chain: each market's question, the probability its automated market maker currently gives YES and NO (percent), when trading ends, the funds in the market, traded volume and, once published, the outcome. Use it for "what are the odds of …" or "which prediction markets are open" questions. Amounts are in the market's payment token (ADA unless `paymentToken` says otherwise). Outcomes are published on chain by the Bodega team, not by a decentralised oracle; most markets are sports events. Odds are a market price, not a forecast you should present as fact: name the source and the time.

Input parameters:

- `limit` (integer): How many markets to return (1-50, default 15).
- `query` (string): Only markets whose question contains this text.
- `sort` (string): Ordering. Default: deadline (soonest first for open markets, latest first otherwise). volume = all-time traded volume; activity = most recently traded.
- `status` (string): open = trading now; awaiting = trading ended, no result published yet; resolved = result published, winners can claim; closed = wound up.

### `get_prediction_market` (~144 tokens)

One prediction market

One Bodega prediction market by its id: the question, current YES and NO probability (percent), shares outstanding per side, funds in the market, volume, deadline, outcome, how the YES probability moved (first, lowest, highest, latest and the last points of its history) and the most recent buys, sales and claims with what was paid per share. Get the id from `list_prediction_markets`. Trading is not done here: `tradeUrl` is the market on Bodega.

Input parameters:

- `marketId` (string, required): Market id as `list_prediction_markets` returns it, e.g. "FC1B_BTC_REACHES_9000".

### `list_masumi_agents` (~262 tokens)

Find AI agent services on Cardano (Masumi)

Search the AI agent services registered in the Masumi registry on Cardano: what each one does, its price, the address of its API, who registered it, and, read from Masumi's escrow contract, how many payments it actually received, from how many distinct buyers and when last. Use it to find an agent that offers a service, or to judge whether a listed agent is used at all. The answer also carries the network totals of the last 30 days. Entries are written by their owners and are not verified.

Input parameters:

- `kind` (string): agent = services that are paid through Masumi's escrow; x402 = HTTP resources paid per call on another chain; all = both.
- `limit` (integer): How many entries to return (1-50, default 10).
- `page` (integer): Page number, from 1.
- `paidOnly` (boolean): true lists only entries that received at least one payment in the indexed history.
- `query` (string): Words to look for in the name, description, tags, author or endpoint, for example "research" or "image".
- `sort` (string): payments = most payments received first; recent = newest registration first; price = cheapest first.

### `get_masumi_agent` (~118 tokens)

One Masumi agent service

Everything indexed about one entry of the Masumi registry: full description, price, API endpoint, capability, author, tags, when and by which transaction it was registered, who holds the registry token, and its latest payments from the escrow contract with their status (locked, result submitted, paid, refunded). Get the identifier from `list_masumi_agents`.

Input parameters:

- `id` (string, required): Agent identifier: the registry policy id followed by the asset name, in hex (the `id` of `list_masumi_agents`).

### `get_programmable_token` (~203 tokens)

Rules and issuer of a programmable token (CIP-113)

What the issuer of a programmable token (Cardano's CIP-113 standard, live since October 2026) can do with it, read from the chain: freeze it in any wallet, take it back without the holder's signature, require approved holders, pause or shut it down, change the rules; who the issuer is (the administrator and the operators with their rights), the block list, supply and holders under the standard's contract, the latest compliance events, and which of this is read from the chain and which can not be read (a token whose issuer wrote their own scripts says so). Without `token` it lists every registered programmable token in one line each. The answer says how far our index reaches (`coverage`): lists and balances are complete only when it says so.

Input parameters:

- `token` (string): Policy id (56 hex) or token unit (policy id + asset name in hex). Leave out to list every registered programmable token.

### `get_programmable_balances` (~174 tokens)

Programmable tokens held by a wallet

The programmable tokens (CIP-113) a wallet holds. They are NOT at the wallet's own addresses: they sit under the standard's shared contract, owned by a credential, so `get_wallet` does not show them. Give an addr1… payment address, a stake1… stake address or a 56-hex owner credential; for a wallet address we look up its payment key and its stake key (the owner can be either). Each holding comes with the token's restrictions in plain words, whether the owner is on the token's block list, and a value when the token has a pool price (most do not).

Input parameters:

- `address` (string, required): addr1… payment address (including a smart-wallet address), stake1… stake address, or a 56-hex owner credential.

### `list_programmable_events` (~226 tokens)

Freeze, unfreeze and seizure history of programmable tokens

What issuers of programmable tokens (CIP-113) have done, each with its transaction: wallets put on or taken off a block list (`freeze`, `unfreeze`), tokens moved out of a wallet by the issuer without the holder's signature (`third_party`: a seizure or forced transfer), mints and burns, pauses and other setting changes (`state_changed`), rule changes, new operators, registrations. Filter by token, by kind or by the wallet credential concerned. An empty list means none are indexed in the period the `coverage` field names, not that none happened before it.

Input parameters:

- `credential` (string): Only events about this owner credential (56 hex): frozen, taken from, or given tokens.
- `kind` (string): Only this kind of event. freeze/unfreeze = block-list changes; third_party = tokens moved by the issuer without the holder.
- `limit` (integer): How many events to return (1-100, default 25).
- `token` (string): Only events of this token: policy id or unit.

### `check_programmable_transfer` (~241 tokens)

Pre-flight check of a programmable token transfer

Would a transfer of a programmable token (CIP-113) from A to B be allowed, and if not, why? Answers only from state we index (the sender's balance under the standard's contract, a pause or shutdown, the block list of either side) and lists what it can NOT know: identity checks signed off chain, the issuer's own transfer script, a rule change before the transaction is built. The best verdict is `nothing_visible_forbids`, never "allowed". A token whose rules are scripts we cannot read answers `rules_unreadable`. Nothing is built or signed.

Input parameters:

- `amount` (string): Amount to send, decimal-adjusted, as plain digits (for example "10" or "2.5").
- `from` (string): Sender: addr1… address (ordinary or smart-wallet), stake1… address or a 56-hex owner credential.
- `to` (string): Receiver: addr1… address (ordinary or smart-wallet), stake1… address or a 56-hex owner credential.
- `unit` (string, required): Token unit: policy id + asset name in hex.

### `analyze_wallet_utxos` (~177 tokens)

Wallet UTxO fragmentation

How fragmented a Cardano wallet's UTxOs are and what tidying them ("unfracking") would release: UTxO count, native assets and policies, ADA locked as minimum-UTxO deposits, UTxOs that hold a single asset, the largest UTxO, and the projected result of the default UTxO-optimiser plan (transactions needed, UTxOs afterwards, ADA released from deposits, network fees). Read-only: no transaction is built; the user reviews and signs in their own wallet on the page in `url`. Amounts are whole ADA. A wallet with more than 600 UTxOs answers `status: "too_large"`.

Input parameters:

- `address` (string, required): addr1… payment address, stake1… stake address, or an ADA Handle written as $name.

### `get_token_prices` (~213 tokens)

Prices of several tokens

Prices of up to 100 Cardano tokens in one call (ADA and USD per token), optionally with the change of the ADA price over windows from 5 minutes to 90 days (percent). Use it instead of calling `get_token` repeatedly when you hold a list of units. A null change means the token did not trade yet at the start of that window; 30d and 90d only reach back as far as our history. Prices come from DEX pools: check liquidity with `get_token` before quoting a thin token.

Input parameters:

- `units` (string, required): Comma separated token units (56-hex policy id + asset name in hex; "lovelace" for ADA), 1 to 100 of them. Get them from `search` or `list_tokens`.
- `windows` (string): Optional comma separated windows for the price change: 5m, 1h, 6h, 24h, 7d, 30d, 90d.

### `get_drep` (~135 tokens)

DRep detail

If the votes cannot be read the answer says so: never conclude "has not voted" from it. Find DRep ids with `list_governance_actions` votes or `search`.

Input parameters:

- `drepId` (string, required): DRep id (drep1…, CIP-129) or its 56-hex credential.

### `get_committee` (~56 tokens)

Constitutional committee

- `status` (string): paid = enacted, pending = open or ratified, rejected = expired or dropped.

### `get_embed_snippet` (~285 tokens)

- `metric` (string): What the badge shows. Pool: return, luck, blocks, saturation, stake, delegators, pool. DRep: votes, participation, power, delegators, drep. Token: price, price-ada, change, token. Default: the identi…
- `style` (string): Badge style: flat, flat-square or for-the-badge.
- `subject` (string, required): What the badge is about: pool, drep or token.

### `get_entity_claim` (~128 tokens)

Pool or DRep page claim

Whether a stake pool or DRep page has been claimed by its operator, the verified links and description, and how an operator claims a page. Only a claim whose status is "verified" was proven with a key of the pool or DRep; "approved" means Realtap reviewed it, which is not a key proof.

Input parameters:

- `id` (string, required): Bech32 id: pool1… for a pool, drep1… for a DRep. `get_stake_pool` and `get_drep` return it.
- `kind` (string, required): pool or drep.

### `get_wrapped_card` (~158 tokens)

Cardano Wrapped 2026 card

Cardano Wrapped 2026: one wallet's year on Cardano (trading, NFTs, staking, governance, an archetype and ranks) with a link to the shareable card. Opens 1 December 2026; before that the tool answers with the launch date and no card. A wallet can opt out, and then there is no card. The first request for a wallet computes the card, which can take a few seconds.

Input parameters:

- `id` (string, required): The wallet: a $handle, a stake1… address or an addr1… address that has a stake part.
- `refresh` (boolean): Recompute the card instead of reading the stored one (honoured at most about once an hour per wallet).

### `build_delegation_transaction` (~430 tokens)

Unsigned stake and vote delegation transaction (nothing is signed or sent)

Build an unsigned Cardano transaction that delegates a wallet's stake to a pool and/or its voting power to a DRep (or to "abstain" / "no-confidence"), for a wallet that signs for itself. Give the wallet's base address (or $handle) and at least one of `pool` and `drep`. Returns the transaction as CBOR hex with its hash, the fee and deposit (the refundable stake-key deposit, currently 2 ADA, only when the stake key is not registered yet), the certificates in plain words, the inputs and the single output that returns everything to the wallet, a read-back of the transaction decoded independently of the builder, the cost worked out from the transaction itself (`cost`), warnings and how to sign and submit it. Both the payment key and the stake key must sign. Refuses when the pool is unknown or retiring, the DRep is unknown or retired, the wallet already delegates there, the address is an enterprise or script address, or there is not enough ADA. Realtap never signs, holds keys or submits: nothing happens until the owner of the address signs and submits it. Call it only when that owner asked to stake or delegate; check the pool or DRep first with `get_stake_pool` or `get_drep`. Limited to a few calls per minute.

Input parameters:

- `address` (string, required): The signer's mainnet base address (addr1…, 103 characters: payment and stake part) or a $handle that resolves to one. Enterprise, script and stake1… addresses cannot delegate.
- `drep` (string): DRep to delegate voting power to: a drep1… id (CIP-129 or legacy), "abstain" (always abstain) or "no-confidence" (always no confidence). Omit to leave the voting delegation as it is.
- `pool` (string): Stake pool to delegate the stake to: a pool1… id or the 56-character hex of its key hash. Omit to leave the stake delegation as it is.

### `get_token_safety` (~107 tokens)

Token safety check ("is this a rug?")

Evidence-based risk check of one token: risk score and level (higher = riskier), fraud flags with their evidence, whether the mint policy is locked, liquidity depth and how much of the LP is locked or burned, holder concentration and what was not checked. Use it before calling a token safe.

Give the fields the kind needs (price_above/price_below: unit + priceAda; pct_move: unit + window + pct; volume_spike: unit + multiple; whale_trade: minAda (+ unit); wallet_activity: address; new_pool: unit or minLiquidityAda; nft_floor_above/below: policyId + floorAda; others: `paramsJson`). Deliver to a signed webhook with `webhookUrl` (public https only; the HMAC secret is returned ONCE, in `webhook.secret`) or to an existing `targetId`; with neither the alert stays in the account inbox. Deliveries are JSON POSTs signed with `X-Realtap-Signature: t=<unix>,v1=<hex HMAC-SHA256 of "<t>.<body>">` (verify it and refuse a t more than 5 minutes off your clock), retried with backoff. Rules per account are limited by plan, and a key may create 20 rules an hour. The result links the delivery log; use `test_alert` to try the webhook.

Input parameters:

- `address` (string): wallet_activity and wallet-based kinds: an addr1… or stake1… address.
- `cooldownSecs` (integer): Smallest time between two alerts of this rule (default depends on the kind).
- `direction` (string): pct_move: which way (default both).
- `drepId` (string): DRep kinds: a drep1… id.
- `floorAda` (number): nft_floor_above / nft_floor_below: floor price level in ADA.
- `kind` (string, required): What to watch. Use `paramsJson` for kinds that need fields not listed below.
- `label` (string): A short name for the token / wallet / pool shown in the alert.
- `minAda` (number): whale_trade: smallest single trade in ADA.
- `minLiquidityAda` (number): new_pool: smallest liquidity in ADA (instead of, or with, `unit`).
- `multiple` (number): volume_spike: last-hour volume as a multiple of the 24 h hourly average (at least 1.5).
- `paramsJson` (string): Optional JSON object text with further parameters for the kind (merged with the fields above), e.g. {"types":["TreasuryWithdrawals"]} for gov_new_action.
- `pct` (number): pct_move: the size of the move in percent.
- `policyId` (string): NFT floor kinds: the collection policy id (56 hex).
- `poolId` (string): Stake pool kinds: a pool1… id.
- `priceAda` (number): price_above / price_below: the price level in ADA.
- `targetId` (integer): Deliver to an existing delivery target of the account instead (see `list_alerts`).
- `unit` (string): Token unit: 56-hex policy id followed by the asset name in hex (no separator). Get it from `search` or `list_tokens`.
- `webhookLabel` (string): Name for a new webhook target.
- `webhookUrl` (string): Public https URL that receives the signed POST. Re-using a URL of the account re-uses its target (no new secret).
- `window` (string): pct_move: the window the move is measured over.

### `list_alerts` (~151 tokens)

List your alert rules and delivery targets

The alert rules your API key created, the account's delivery targets (signing secrets are never shown) and the most recent deliveries with their status, so you can see whether a webhook is working. Only a key's own rules can be changed, deleted or tested; with `all` the account's other rules (made on the website or by other keys) are listed too, read-only (`own: false`), wallet addresses cut to a prefix and without their targets. Needs an API key.

Input parameters:

- `all` (boolean): Also list the account's other rules, read-only and redacted.
- `deliveries` (integer): How many recent deliveries to include (0-20, default 5).

### `delete_alert` (~70 tokens)

Delete an alert rule

Deletes an alert rule that your API key created (rules made on the website or by other keys cannot be deleted this way). Its past alerts stay in the inbox and delivery log. Needs an API key.

Input parameters:

- `ruleId` (integer, required): Rule id, from `list_alerts` or `create_alert`.

### `test_alert` (~125 tokens)

Send a test message to an alert target

Queues a signed test message (event "test") to one delivery target, or to every target of one of your key's own rules, and waits a few seconds for the result: status sent, retry or dead with the HTTP status or error. A target can be tested a few times every 10 minutes. Needs an API key.

Input parameters:

- `ruleId` (integer): Or: test every target of this rule.
- `targetId` (integer): The delivery target to test (from `list_alerts` or the `webhook` block of `create_alert`).

### `get_wallet_risk` (~145 tokens)

Wallet risk score (a heuristic)

A transparent 0-100 risk score for a wallet with named reasons and the evidence behind each: issuer block-list membership, tokens the wallet minted that are now rated danger, flagged tokens it bought (tokens merely sent to it never count), round trips with itself, bot-like trading, a very new wallet. `notChecked` lists what was not scored (mixers and sanctions lists, scam-labelled counterparties). It is a heuristic, not an accusation: quote `disclaimer` with the score and never present it as proof of wrongdoing. Wallets without a stake key get no score.

Input parameters:

- `address` (string, required): addr1…, stake1… or $handle.

### `get_token_staking` (~196 tokens)

Token staking programs

Tokens staked in a project's own contracts: Iagon (IAG), Indigo INDY staking and Minswap yield farms (LP tokens). Without `token`: the programs with TVL in ADA, stakers, 24 h / 7 d change of the staked amount and the share held by the ten largest stakers. With `token` (a unit or a ticker such as IAG, INDY): top stakers, size distribution, 7 / 30 day inflows and outflows, lock states and the daily history. Rewards are paid off chain and are not part of the figures.

Input parameters:

- `limit` (integer): How many programs to return (1-25, default 15).
- `token` (string): A staked unit (56-120 hex) or a ticker / name fragment from the list (IAG, INDY, MIN). Leave out to list the programs.

## Common questions

### What is the Realtap MCP server?

Realtap is an MCP server listed in the public MCP registry as io.github.CSteenkamp/realtap. Live Cardano data (token prices, DEX trades, pools, wallets, NFTs, staking, governance). Read-only. This page covers its hosted endpoint (https://realtap.app/api/mcp).

### Is the Realtap MCP server safe to use?

Realtap scores 67 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Realtap MCP server expose?

Realtap exposes 82 tools: search, list_tokens, get_token, get_token_candles, get_pool, and 77 more. Their descriptions and schemas cost roughly 12,562 tokens of context every time the server is loaded.

### Does the Realtap MCP server require authentication?

No. We connected to Realtap without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Realtap MCP server still maintained?

Realtap is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
