## 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 2026-08-03.

- **Endpoint Security**: 51/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 85 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS check failed: the endpoint is reachable over plaintext HTTP.
  - 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**: 63/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 9421 tokens (~110/item across 85 items; 85 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 86/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 59% of tool parameters carry a description.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

The smart-money / whale-watching flow feed trading and copy-trade agents poll to catch big money moving — a Nansen-style whale alert without the subscription. Each whale chains into smart_money_wallet_activity and wallet_portfolio. Live from Blockscout.

Input parameters:

- `chain` (string): base|ethereum (default base)
- `limit` (number): 1-50, default 15
- `min_usd` (number): Minimum transfer size in USD (default 10000)

- `x_payment` (string)

### `smart_money_wallet_activity` (~180 tokens)

$0.01 via x402: smart-money wallet profile — what any wallet is DOING right now: net token flows in/out with USD values (which tokens it's accumulating vs distributing), recent transaction methods (swap/transfer/approve), activity level + last-active time, top counterparties, and native ETH balance. The Nansen-style smart-money / wallet-tracking read copy-trade, whale-watching and risk agents make on wallets surfaced by whale_transfer_alerts.

Input parameters:

- `chain` (string): base|ethereum|optimism|arbitrum|polygon (default base)
- `wallet` (string, required): Wallet address to profile (0x...)
- `x_payment` (string)

### `wallet_portfolio` (~133 tokens)

The 'bagcheck' call for copy-trading, whale-watching, risk and research agents. Chains: base, ethereum, optimism, arbitrum, polygon. Live from Blockscout.

Input parameters:

- `chain` (string): base|ethereum|optimism|arbitrum|polygon (default base)
- `wallet` (string, required): Wallet address (0x...)
- `x_payment` (string)

### `chain_native_balance` (~141 tokens)

$0.01 via x402: the core on-chain RPC read — any address's native coin balance (ETH/POL/xDAI) with live USD value and outgoing transaction count, across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. The high-frequency balance check wallet-tracking, settlement and trading agents poll constantly. Live from Blockscout; 6 chains vs onesource's Ethereum-only.

Input parameters:

- `address` (string, required): Account address (0x...)
- `chain` (string): base|ethereum|optimism|arbitrum|polygon|gnosis (default base)
- `x_payment` (string)

### `chain_block_header` (~168 tokens)

$0.01 via x402: the full header of any block — timestamp and age, transaction count, gas used vs limit with a utilization ratio and congested flag, base fee in gwei, miner and parent hash. /chain/block-number says WHERE the chain is; this says WHEN that block happened and how contested it was. Accepts a height or latest/finalized/safe. Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis.

Input parameters:

- `chain` (string): base|ethereum|optimism|arbitrum|polygon|gnosis (default base)
- `number` (string): Block height (decimal or 0x hex) or latest|finalized|safe|earliest (default latest)
- `x_payment` (string)

### `chain_event_logs` (~198 tokens)

$0.02 via x402: raw event logs by contract address and/or indexed topics over a block range (eth_getLogs) — the indexing primitive. Defaults to a 25-block window and narrows automatically when a node refuses on result size, and every cap or narrowing that bit is named in the response instead of silently applied. Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis.

Input parameters:

- `address` (string): Contract address to filter on (0x...)
- `chain` (string): base|ethereum|optimism|arbitrum|polygon|gnosis (default base)
- `fromBlock` (string)
- `toBlock` (string)
- `topic0` (string): Event signature topic (32-byte 0x...)
- `topic1` (string)
- `topic2` (string)
- `topic3` (string)
- `x_payment` (string)

### `chain_fee_history` (~151 tokens)

$0.02 via x402: EIP-1559 fee history — base-fee trend over N blocks, priority-fee percentiles (10/50/90), mean block utilization, and a recommended maxFeePerGas / maxPriorityFeePerGas with the reasoning stated. A single gas number cannot tell you whether fees are rising; this can. Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis.

Input parameters:

- `blocks` (number): Recent blocks to sample, 1-100 (default 20)
- `chain` (string): base|ethereum|optimism|arbitrum|polygon|gnosis (default base)
- `x_payment` (string)

### `chain_token_identity` (~157 tokens)

$0.01 via x402: ERC-20 name, symbol, decimals and total supply read straight off the contract, plus an existence check. Because it reads the contract and not an indexer it answers for tokens minted MINUTES ago and on chains no explorer covers — the gap that makes indexer-backed lookups return nothing for a fresh launch. Legacy bytes32 name/symbol decoded; a missing decimals() is flagged, not silently assumed. The first read to make on an unknown contract.

Input parameters:

- `chain` (string): base|ethereum|optimism|arbitrum|polygon|gnosis (default base)
- `token` (string): ERC-20 contract address (0x...)
- `x_payment` (string)

### `chain_confirmations` (~163 tokens)

$0.01 via x402: did this transaction land, how deep is it buried, and is it safe to treat as FINAL on this chain. Returns status, block, tip, confirmations, gas used, fee paid and log count, compared against the chain's own finality threshold (Ethereum 64, Polygon 128, OP-stack 60). A success with two confirmations is not a settled payment. Also distinguishes 'no receipt yet' from 'failed' — conflating those is how agents double-spend.

Input parameters:

- `chain` (string): base|ethereum|optimism|arbitrum|polygon|gnosis (default base)
- `hash` (string): Transaction hash (0x + 64 hex)
- `x_payment` (string)

### `chain_l1_data_fee` (~175 tokens)

$0.02 via x402: the L1 data-availability fee an OP-stack transaction pays ON TOP of L2 execution gas — usually the larger half of the bill, and the half ordinary gas estimators leave out. Answered by the chain's own GasPriceOracle.getL1Fee rather than a reimplemented formula, so it stays correct across Ecotone, Fjord and later forks. Pass data=0x... to price your actual transaction exactly. Base and Optimism only.

Input parameters:

- `bytes` (number): Transaction size in bytes, 1-200000 (default 1200)
- `chain` (string): base|optimism (OP-stack only)
- `data` (string): 0x calldata of your actual transaction — priced exactly
- `x_payment` (string)

### `chain_nft_owner` (~169 tokens)

$0.01 via x402: who owns an NFT right now and where its metadata lives — ownerOf, tokenURI, collection name and symbol in one call, with the tokenURI classified as ipfs / on-chain data URI / http so you know how to fetch it. Read from the contract, so it is correct for tokens minted seconds ago and collections no marketplace has indexed. Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis.

Input parameters:

- `chain` (string): base|ethereum|optimism|arbitrum|polygon|gnosis (default base)
- `contract` (string): ERC-721 contract address (0x...)
- `token_id` (string): Token ID (decimal or 0x hex)
- `x_payment` (string)

### `chain_batch_reads` (~188 tokens)

$0.05 via x402: up to TEN on-chain reads for ONE payment, run in parallel — native balance, nonce, contract-code check, ERC-20 balance, block number and gas price in any combination. Reconciling a wallet normally costs one payment per read; this is the same data for a fraction of the calls and the latency. Per-read failures are reported individually with a partial flag, so a batch never claims success it did not have.

Input parameters:

- `chain` (string): base|ethereum|optimism|arbitrum|polygon|gnosis (default base)
- `reads` (string): Comma-separated ops, max 10: balance:0xADDR | nonce:0xADDR | code:0xADDR | erc20:0xTOKEN:0xWALLET | blocknumber | gas
- `x_payment` (string)

### `chain_heartbeat` (~138 tokens)

$0.005 via x402: one pre-action heartbeat replaces chain-id + block-tip + block-freshness + gas + fee-history + finality calls. One-sixth the price of chain ID + block number + gas separately, with one round trip and more data. Returns an identity-checked HEALTHY/CONGESTED/STALE verdict across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis and Robinhood Chain.

Input parameters:

- `chain` (string): base|ethereum|optimism|arbitrum|polygon|gnosis|robinhood (default base)
- `x_payment` (string)

### `chain_gas_price` (~126 tokens)

$0.01 via x402: live network gas prices (slow/average/fast, in gwei) for any chain — the pre-transaction read every trading, sniping and settlement agent makes before sending a tx to size the fee. Across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. Live from Blockscout; one paid call instead of running your own RPC.

Input parameters:

- `chain` (string): base|ethereum|optimism|arbitrum|polygon|gnosis (default ethereum)
- `x_payment` (string)

### `connect_token` (~136 tokens)

$0.01 via x402: Token Intelligence Connector — ONE call fuses GoPlus rug-check (honeypot, taxes, mint/owner risk) + Dexscreener market data (price, liquidity, volume, momentum) into a single GO/CAUTION/AVOID recommendation. The aggregator call trading & sniping agents make instead of chaining rug-check + dex separately.

Input parameters:

- `address` (string, required): Token contract address 0x...
- `chain` (string): ethereum|base|bsc|polygon|arbitrum|optimism|avalanche (default ethereum)
- `x_payment` (string)

### `pretrade_full_report` (~156 tokens)

$0.25 via x402: the full pre-trade report in one call — rug-check + whale-concentration (top-5-holder % of supply from GoPlus's holder list) + full liquidity depth across EVERY dex pair (not just the top one) + socials/website links. Same free upstreams as the $0.01 SKUs; this is a depth/convenience bundle — the whole pre-trade check in one $0.25 call.

Input parameters:

- `address` (string, required): Token contract address 0x...
- `chain` (string): ethereum|base|bsc|polygon|arbitrum|optimism|avalanche (default ethereum)

- `x_payment` (string)

### `eu_tender_intelligence` (~124 tokens)

$0.01 via x402: EU Tender Intelligence — live public procurement tenders across all 27 EU member states by keyword/sector, from the official EU TED database.
