## 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 2026-11-04.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - 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**: 74/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1206 tokens (~150/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 97/100
  - Stability observed for 29 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**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (8)

### `exit_cost` (~195 tokens)

What selling a token really returns

Cryptominium measures, every day, what a fixed-size sell of each tracked token actually returns versus its quoted price, by querying live DEX routing on Base, Ethereum and BNB Chain. Use this when someone asks whether a token can really be sold, how liquid it is, or what they would get for a position. Returns the latest measured exit friction (% lost to price impact), the dollars received, the date measured, and a citation — plus, where the token trades on Kraken or Coinbase, what the same sell loses against those order books, and this week's changes as short tags with the 7-day high, low and latest price. Not a price feed and not advice.

Input parameters:

- `chain` (string): Optional: base, ethereum or binance-smart-chain.
- `token` (string, required): Ticker, name or contract address, e.g. "AERO", "pepe", "0x9401…".

### `coin_profile` (~198 tokens)

CM Profile: what is known about a coin, and what is not

The Cryptominium Profile (CM Profile) of a tracked coin, in four fixed groups: what Cryptominium has established (contracts matched, chains), what it has measured (the cost of selling on-chain and on exchange order books, with dates; price history), what it has written with sources (what the coin can do and through which company), and what it has not established. Use this when someone asks what is known about a coin, how well documented it is, or whether it depends on a company. Each line links to its evidence. Also returns this week's changes as short tags and the 7-day high, low and latest price, as the coin page chart marks them. A record, not a rating: it is not a view on whether to hold the coin.

Input parameters:

- `token` (string, required): Ticker, name or contract address, e.g. "USDC", "pepe", "0x8335…".

### `powermap` (~152 tokens)

PowerMap: who holds power over a coin

Cryptominium's PowerMap: which company or group holds which of nine powers over a coin (freeze, pause, mint, redeem, custody, govern, validate, pay out, bridge), each repeating that party's own terms with a link and a date, plus on-chain readings of mint and freeze authority. Answers questions about a coin ("USDC"), a company ("Circle"), or a class of coins ("which stablecoins can be frozen"), and says what is not established. It records who can use a power, not whether they will.

Input parameters:

- `query` (string, required): A coin, a company, or a question, e.g. "USDC", "Circle", "which stablecoins can be frozen".

### `exit_index` (~98 tokens)

The monthly Exit-Friction Index

The Cryptominium Exit-Friction Index: each month, the median share of value lost when selling a fixed $100,000 position across every token with a live on-chain market, with quartiles and the share of tokens losing more than half. Use for questions about overall crypto market liquidity or how hard it is to exit altcoins. Optional month as YYYY-MM; defaults to the latest.

Input parameters:

- `month` (string): YYYY-MM, optional.

### `identify_address` (~136 tokens)

What a crypto address is

Identifies a public address or ENS name without being told what it is: wallet or contract, which of seven EVM chains it has been active on (read: Base, Ethereum, BNB Chain; identified: Arbitrum, Polygon, Optimism, Avalanche), EIP-7702 delegation, the token if it is one Cryptominium tracks. Bitcoin addresses are checksum-verified and read; Solana accounts are identified (wallet, mint, token account, program). The address is not stored. A recovery phrase or private key is refused without being looked up.

Input parameters:

- `address` (string, required): A public address or ENS name.

### `explain_transaction` (~85 tokens)

What a transaction did

Reads an EVM transaction hash on Base, Ethereum or BNB Chain from its receipt logs: whether it succeeded, what moved to and from whom (with token symbols and decimals), what it cost in fees, and any token approvals it granted or revoked, including unlimited ones. The hash is not stored.

Input parameters:

- `hash` (string, required): 0x followed by 64 hex characters.

### `what_is` (~162 tokens)

What a crypto word means

Cryptominium's hand-written crypto library: what a crypto, blockchain, trading or crypto-technology term means in plain English, what it means in practice for someone holding or sending crypto, how it works, a common misconception, and the primary source it was checked against with the date. For ideas such as "code is law" or "sound money", the strongest case for and against, each sourced. Accepts a term ("impermanent loss"), a question ("what is an NFT"), two terms to contrast ("proof of work vs proof of stake") or a topic ("defi terms"). Written ahead of time, not generated.

Input parameters:

- `term` (string, required): A crypto term, a "what is" question, "X vs Y", or a topic.

### `search` (~74 tokens)

Search Cryptominium

Cryptominium's crypto search: says what a query is (ticker, address, transaction, comparison, a question about selling a position, a directory category…) and returns the matching coins and Cryptominium pages. Use it to find the right Cryptominium page for a crypto question.

Input parameters:

- `query` (string, required): Anything crypto.

## Common questions

### What is the Cryptominium MCP server?

Cryptominium is an MCP server listed in the public MCP registry as com.cryptominium/cryptominium. What a crypto position would really sell for: measured exit costs, address and transaction lookups. This page covers its hosted endpoint (https://cryptominium.com/mcp).

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

Cryptominium scores 85 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 Cryptominium MCP server expose?

Cryptominium exposes 8 tools: exit_cost, coin_profile, powermap, exit_index, identify_address, and 3 more. Their descriptions and schemas cost roughly 1,100 tokens of context every time the server is loaded.

### Does the Cryptominium MCP server require authentication?

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

### Is the Cryptominium MCP server still maintained?

Cryptominium is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
