Frequently asked questions

What is an MCP server?

An MCP (Model Context Protocol) server exposes tools that AI clients like Claude can discover and call. This project creates such a server on Cloudflare Workers.

How do I deploy my own instance?

Run `npx wrangler kv namespace create OAUTH_KV`, add the KV namespace ID to `wrangler.jsonc`, then run `npm run deploy`. Your server will be available at a `workers.dev` URL.

How do I connect Claude Desktop?

Update your Claude configuration file to add an MCP server entry using `npx mcp-remote` as the command and your server’s SSE URL (e.g., `https://worker-name.account-name.workers.dev/sse`) as the argument.

What transport protocol does the server use?

It uses Server-Sent Events (SSE) – connect to the `/sse` endpoint.

How can I debug connection issues?

Restart Claude, or try connecting directly via the command line with `npx mcp-remote http://localhost:8787/sse`. If needed, clear cached auth files with `rm -rf ~/.mcp-auth`.
