MCP Anvil Lite (free)

A minimal, correct starting point for a Model Context Protocol server in TypeScript — stdio transport, one tool, on the stable SDK. Clone it, wire it into Claude Desktop, and you have a working MCP server in minutes.

npm install
npm run build
npm start          # runs the stdio server
npm test

Use it with Claude Desktop

{
  "mcpServers": {
    "anvil-lite": { "command": "node", "args": ["/absolute/path/to/mcp-anvil-lite/dist/stdio.js"] }
  }
}

Add your own tool: copy the echo block in src/server.ts, change the Zod schema + handler. Done.

Going to production? → MCP Anvil Pro

This lite kit is deliberately minimal. When you need to ship, the Pro kit hands you the parts that take a week to get right — and the security gotchas most tutorials quietly skip:

Ship a production MCP server in an hour, not a week → mcpanvil.dev
