What a crypto position would really sell for: measured exit costs, address and transaction lookups.

com.cryptominium/cryptominium MCP Server

The com.cryptominium/cryptominium Model Context Protocol (MCP) server provides functionality for “a crypto position” focused on measured exit costs, along with address and transaction lookups. It is described as answering what a crypto position would really sell for, using information related to those queries.

🛠️ Key Features

Measured exit costs
Address lookup
Transaction lookup

🚀 Use Cases

Estimating exit costs for a crypto position
Looking up details by blockchain address
Looking up details for specific transactions

⚡ Developer Benefits

Supports context retrieval for crypto position valuation based on exit-cost measurement
Enables address- and transaction-based workflows via MCP

⚠️ Limitations

Available information does not specify additional tools, parameters, outputs, or supported blockchain networks.

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. Not a price feed and not advice.

Parameters2

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

  "type": "object",
  "properties": {
    "token": {
      "type": "string",
      "description": "Ticker, name or contract address, e.g. \"AERO\", \"pepe\", \"0x9401…\"."
    },
    "chain": {
      "type": "string",
      "description": "Optional: base, ethereum or binance-smart-chain."
    }
  },
  "required": [
    "token"
  ]
}

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.

Parameters1

month

string

optional

YYYY-MM, optional.

Raw schema

  "type": "object",
  "properties": {
    "month": {
      "type": "string",
      "description": "YYYY-MM, optional."
    }
  }
}

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.

Parameters1

address

string

required

A public address or ENS name.

Raw schema

{
  "type": "object",
  "properties": {
    "address": {
      "type": "string",
      "description": "A public address or ENS name."
    }
  },
  "required": [
    "address"
  ]
}

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.

Parameters1

hash

string

required

0x followed by 64 hex characters.

  "type": "object",
  "properties": {
    "hash": {
      "type": "string",
      "description": "0x followed by 64 hex characters."
    }
  },
  "required": [
    "hash"
  ]
}

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.

Parameters1

query

string

required

Anything crypto.

Raw schema

{
  "type": "object",
  "properties": {
    "query": {

Cryptominium MCP server

What a crypto position would really sell for: measured exit costs, the monthly Exit-Friction Index, and address and transaction lookups. Read-only.

code

https://cryptominium.com/mcp

Streamable HTTP. No account, no key, no cost.

This repository holds the connection files only: the listing for the official MCP Registry, a Gemini CLI extension, a Cursor plugin and the logo. The server itself runs at the address above and is not published here.

What it does

Every day, Cryptominium measures what a $100,000 sell of each tracked token actually returns against its quoted price, on Base, Ethereum and BNB Chain and on exchange order books. Every answer carries its measurement date and a link to the page it came from.

Tool	What it answers
`exit_cost`	What selling a token really returns, measured, with the date
`exit_index`	The monthly Exit-Friction Index: the median share of value lost selling $100,000, across every measured token
`coin_profile`	CM Profile: what is known about a coin, what is measured, and what is not known
`powermap`	PowerMap: which company or group holds which of nine powers over a coin (freeze, pause, mint, redeem, custody, govern, validate, pay out, bridge)
`identify_address`	What a public address or ENS name is: wallet or contract, which chains, which token
`explain_transaction`	What an EVM transaction did: what moved, the fee, approvals granted or revoked
`what_is`	What a crypto word means, in plain English, with sources
`search`	Cryptominium search: what a query is, and the matching coins and pages

No trading, no wallet connection, and nothing a caller sends is stored. Measurements, not advice: Cryptominium does not recommend buying, selling or holding anything.
