FAQ from Remote MCP Server on Cloudflare

How do I connect Claude Desktop to a deployed server?

Update the claude_desktop_config.json with mcp-remote pointing to your workers.dev URL followed by /sse, for example https://worker-name.account-name.workers.dev/sse.

What transport does the server use?

The server uses Server-Sent Events (SSE) transport, configured by connecting to the /sse endpoint.

How do I deploy my own version?

Create a KV namespace with npx wrangler kv namespace create OAUTH_KV, add the namespace ID to wrangler.jsonc, then run npm run deploy.

How can I debug connection issues?

Restart Claude, test the connection directly with npx mcp-remote http://localhost:8787/sse, or clear cached auth data with rm -rf ~/.mcp-auth.

What authentication method is used?

The server implements OAuth login. In local development a mock login screen accepts any email and password; in production the deployed Worker handles OAuth flows.
