FAQ from Remote MCP Server on Cloudflare

What transport protocol does the remote MCP server use?

It uses Server-Sent Events (SSE). The local endpoint is http://localhost:8787/sse and the remote endpoint is https://worker-name.account-name.workers.dev/sse.

How do I connect Claude Desktop to the server?

In Claude Desktop’s config file, add an entry using the npx mcp-remote command pointing to the server’s SSE URL, for example: "command": "npx", "args": ["mcp-remote", "http://localhost:8787/sse"].

How do I handle authentication locally?

When testing locally, the MCP Inspector or Claude Desktop will navigate to a mock login screen where you can input any email and password to log in.

How do I deploy to Cloudflare?

Run npx wrangler kv namespace create OAUTH_KV to create a KV namespace, add its ID to wrangler.jsonc, then run npm run deploy.

How can I debug connection issues?

Restart Claude, try connecting with npx mcp-remote http://localhost:8787/sse from the command line, or clear the ~/.mcp-auth directory.
