Multichain Server

multichain-mcp MCP server multichain-mcp MCP server

The only MCP server that gives AI agents native access to Stacks, Celo, and Base — from a single npm package.

Connect Claude Desktop, Cursor, or any MCP-compatible AI to 3 blockchains in under 5 minutes.

Why this exists

Building an AI agent that interacts with Web3 today means writing separate integrations for every chain. This package ships a production-ready MCP server with 5 battle-tested tools across Stacks (Bitcoin L2), Celo, and Base — no RPC keys required to start.
