Cryptominium

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.

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.
