Summary
A no-auth MCP server that connects directly to CoinMarketCap's API with 30 tools covering crypto data, metrics, and on-chain analytics. Hosted by Junct and deterministically generated from the official API spec, so every tool maps 1:1 to a real endpoint. You get streamable HTTP transport, no API key required, and it's free to use. Reach for this when you need Claude to pull live crypto prices, market caps, trading volumes, or chain data without managing authentication or rate limits. Add the URL to your MCP config and you're querying crypto markets in seconds.
