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. How we score → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability74
- AI-judged instruction clarity (excellent).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management97
- Stability observed for 29 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
coin_profile CM Profile: what is known about a coin, and what is not ~198
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.
| Name | Type | Req | Description |
|---|---|---|---|
| token | string | yes | Ticker, name or contract address, e.g. "USDC", "pepe", "0x8335…". |
No output schema declared.
No examples provided.
exit_cost What selling a token really returns ~195
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.
| Name | Type | Req | Description |
|---|---|---|---|
| chain | string | – | Optional: base, ethereum or binance-smart-chain. |
| token | string | yes | Ticker, name or contract address, e.g. "AERO", "pepe", "0x9401…". |
No output schema declared.
No examples provided.
exit_index The monthly Exit-Friction Index ~98
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.
| Name | Type | Req | Description |
|---|---|---|---|
| month | string | – | YYYY-MM, optional. |
No output schema declared.
No examples provided.
explain_transaction What a transaction did ~85
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.
| Name | Type | Req | Description |
|---|---|---|---|
| hash | string | yes | 0x followed by 64 hex characters. |
No output schema declared.
No examples provided.
identify_address What a crypto address is ~136
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.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | A public address or ENS name. |
No output schema declared.
No examples provided.
powermap PowerMap: who holds power over a coin ~152
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.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | A coin, a company, or a question, e.g. "USDC", "Circle", "which stablecoins can be frozen". |
No output schema declared.
No examples provided.
search Search Cryptominium ~74
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.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | Anything crypto. |
No output schema declared.
No examples provided.
what_is What a crypto word means ~162
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.
| Name | Type | Req | Description |
|---|---|---|---|
| term | string | yes | A crypto term, a "what is" question, "X vs Y", or a topic. |
No output schema declared.
No examples provided.
How do I install the Cryptominium MCP server?
