FAQ from Remote MCP Server on Cloudflare

How do I connect Claude Desktop to my local MCP server?

Edit Claude’s configuration file and add an entry for the server with "command": "npx" and "args": ["mcp-remote", "http://localhost:8787/sse"]. Restart Claude and log in through the browser.

How do I deploy to Cloudflare?

Run npx wrangler kv namespace create OAUTH_KV and follow the prompt to add the namespace ID to wrangler.jsonc. Then run npm run deploy.

How do I connect a remote MCP client after deployment?

Use the MCP Inspector with the SSE transport and enter your Worker’s URL (e.g., https://worker-name.account-name.workers.dev/sse) as the server URL, then click “Connect”.

What transport and authentication does the server use?

The server uses SSE (Server-Sent Events) for transport and implements OAuth login. During local development a mock login screen is shown; after deployment OAuth is handled via Cloudflare Workers.

How can I debug connection issues?

Restart Claude, or test connectivity directly with the command npx mcp-remote http://localhost:8787/sse. In rare cases, clear the files in ~/.mcp-auth by running rm -rf ~/.mcp-auth.
