Coingecko Mcp

junct-bot/coingecko-mcp

A deterministically generated MCP wrapper around CoinGecko's public API that exposes 36 tools for cryptocurrency data and analytics. Each tool maps directly to a real CoinGecko endpoint, so you get price data, market metrics, historical charts, and on-chain analytics without needing an API key. Hosted by Junct and accessible via streamable HTTP transport. Reach for this when you need Claude to pull live crypto market data, compare token prices, or analyze DeFi metrics without you having to wire up the CoinGecko API yourself. The 1:1 endpoint mapping means no hallucinated tools or phantom capabilities, just straightforward access to whatever CoinGecko exposes publicly.
