  2. Merge the snippet below into it.

Description

CoinMarketCap's own Model Context Protocol server, hosted at https://mcp.coinmarketcap.com/mcp over streamable HTTP. Nothing to install and no npx wrapper — point an MCP client at the URL and pass an API key.

What the twelve tools cover
  • Market data — quotes, market cap and rankings across 10,000+ cryptocurrencies.
  • Technical analysis — moving averages, MACD, RSI and pivot points, computed server-side so the model is not asked to do arithmetic on a price series.
  • On-chain metrics — holder distribution and supply breakdown.
  • Global overview — total market cap, BTC dominance and the Fear & Greed Index.
  • Narratives and macro — trending sectors and scheduled macro events.
  • News and semantic search across CoinMarketCap's crypto documentation.
Access

Authentication is an API key in the X-CMC-MCP-API-KEY header. The Basic plan is free and allows 30 calls per minute against 10,000 monthly credits, which is enough for interactive use from a single agent. Builder, Startup, Growth, Professional and Enterprise tiers raise the rate limit (from 60 calls/minute) and unlock endpoints such as OHLCV history and exchange pairs.

Unusually, the server also accepts x402 — pay-per-call in USDC at $0.01 per call with no API key at all, which suits an autonomous agent that has a wallet but no account.
