CoinMarketCal MCP: the crypto events calendar in your AI app

CoinMarketCal tracks crypto events for 14,000+ coins, each one dated, sourced and scored for impact. Your AI app can check what's coming up for a coin, such as announcements or releases, without you calling the CoinMarketCal API by hand. ContextGate connects it to Claude, ChatGPT and Cursor and keeps a record of every lookup.

  • Check where an event comes from before you act on it, since each one is sourced.
  • Rank the week's events by impact score to see which could move the market.
  • Look up events across more than 14,000 coins.

The full tool list appears in ContextGate after you connect.
