FAQ from Remote MCP Server on Cloudflare

What transport does the server use?

The server communicates over SSE. Clients connect to the /sse endpoint.

How do I authenticate?

The server implements an OAuth login flow. During local development a mock login screen appears; after deployment real OAuth is used.

What runtime or dependencies are required?

Node.js and npm are needed for local development. Deployment requires a Cloudflare account and the Wrangler CLI.

Where does authentication data live?

OAuth state is stored in a Cloudflare KV namespace (OAUTH_KV) that you create during deployment.

How do I debug connection issues?

Restart Claude, or test directly with npx mcp-remote http://localhost:8787/sse. Clearing ~/.mcp-auth can resolve stale auth files.
