Inside the `init()` method of `src/index.ts`, define each tool using `this.server.tool(...)`. Refer to the Cloudflare documentation on MCP tools for details.

How do I connect to Cloudflare AI Playground?

Go to https://playground.ai.cloudflare.com/, enter your deployed SSE URL, and the tools will be available directly in the playground.

How do I connect to Claude Desktop?

Install the `mcp-remote` proxy via npm, then add a configuration entry in Claude Desktop pointing to your server's SSE URL. Restart Claude to see the tools.

Does this server require authentication?

No, the server is built without authentication, making it suitable for testing and development.
