Define each tool inside the `init()` method of `src/index.ts` using the `this.server.tool(...)` method.

How do I connect Claude Desktop to the server?

Use the `mcp-remote` proxy (npm package) and configure it as an MCP server in Claude Desktop’s `claude_desktop_config.json` with the command `npx mcp-remote <your-sse-url>`.
