FAQ from Remote MCP Server on Cloudflare

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.
