About
Crypto APIs MCP Server gives AI agents direct access to blockchain data across 20+ networks including Ethereum, Bitcoin, Solana, XRP, and Kaspa. It aggregates 50 tools covering address balances, transaction history, fee estimation, smart contract data, market prices, HD wallet management, transaction preparation, and webhook subscriptions — all behind a single HTTP endpoint. Connect to all tools at once or scope your session to a single product for a lighter context. No local setup needed — just point your MCP client to the hosted endpoint with your API key.
