    Lists tools

    tools/list returned 8 tools.

  • Pass
    Current protocol

    Negotiated 2025-06-18. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 1156 ms over 2 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 1207 ms over 2 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    2 of 2 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Pass
    Stable tool list

    No tool was removed and no required parameter was added in the last 30 days.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured

    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Pass
    Source repo linked

    A repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

Capabilities

Tools 8

coin_profile

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.

Discovered
exit_cost

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.

Discovered
exit_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.

Discovered
explain_transaction

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.

Discovered
identify_address

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.

Discovered
powermap

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.

Discovered
search

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.

Discovered
what_is

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.
