FAQ from Remote MCP Server on Cloudflare
How do I debug connection issues?
Restart Claude, or try connecting directly to your MCP server using npx mcp-remote http://localhost:8787/sse. Clearing cached auth files with rm -rf ~/.mcp-auth may also help.

Set the transport type to SSE and enter http://localhost:8787/sse (or your deployed Workers URL) as the server URL, then click “Connect”. You will be prompted to log in.
How do I connect Claude Desktop to the remote server?
Update the Claude configuration file to use npx mcp-remote with your Workers URL (e.g., https://worker-name.account-name.workers.dev/sse) as an argument, then restart Claude.
What are the deployment prerequisites?
You need a Cloudflare account and must create a KV namespace with npx wrangler kv namespace create OAUTH_KV, then add the namespace ID to wrangler.jsonc before deploying with npm run deploy.
