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.

ToolWhat it answers
exit_costWhat selling a token really returns, measured, with the date
exit_indexThe monthly Exit-Friction Index: the median share of value lost selling $100,000, across every measured token
coin_profileCM Profile: what is known about a coin, what is measured, and what is not known
powermapPowerMap: which company or group holds which of nine powers over a coin (freeze, pause, mint, redeem, custody, govern, validate, pay out, bridge)
identify_addressWhat a public address or ENS name is: wallet or contract, which chains, which token
explain_transactionWhat an EVM transaction did: what moved, the fee, approvals granted or revoked
what_isWhat a crypto word means, in plain English, with sources
searchCryptominium 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.

Try asking

  • "What would I really get selling $100,000 of YFI?"
  • "What was the exit-friction index last month?"
  • "What is this address: vitalik.eth"
  • "Who can freeze USDC?"

Connect

Claude (claude.ai or Claude Desktop): Settings → Connectors → Add custom connector, URL https://cryptominium.com/mcp.

Claude Code:

claude mcp add --transport http cryptominium https://cryptominium.com/mcp

Gemini CLI:

gemini extensions install https://github.com/wanchwolfred-arch/cryptominium-mcp

Cursor: install the Cryptominium plugin from the Cursor Marketplace, or add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "cryptominium": { "url": "https://cryptominium.com/mcp" }
  }
}

VS Code: Command Palette → "MCP: Add Server" → HTTP → https://cryptominium.com/mcp.

Any other client that speaks streamable HTTP can use the URL directly.

Citing
