multichain-mcp server

@wkalidev/multichain-mcp

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.

Pricing

Tools included

All write operations return unsigned transactions — your users always sign with their own wallet. Non-custodial by design.

Install

npm install @wkalidev/multichain-mcp

Claude Desktop setup

Add to your claudedesktopconfig.json:

{
  "mcpServers": {
    "multichain": {
      "command": "npx",
      "args": ["-y", "@wkalidev/multichain-mcp"],
      "env": {
        "MULTICHAIN_LICENSE_KEY": "your-license-key"
      }
    }
  }
}

Omit the env block to run on the Free tier. Restart Claude Desktop after adding your key.
