FAQ from Remote MCP Server on Cloudflare

How do I connect Claude Desktop to the remote server?

Update your Claude configuration to use mcp-remote with the server’s workers.dev URL (e.g., https://worker-name.account-name.workers.dev/sse). Restart Claude – a browser window will open for OAuth login.

What transport type is used?

The server uses Server-Sent Events (SSE). When connecting via MCP Inspector, set Transport Type to SSE and enter the server URL followed by /sse.

What are the deployment steps?

Create a KV namespace with npx wrangler kv namespace create OAUTH_KV, add its ID to wrangler.jsonc, then run npm run deploy. The server will be available at a workers.dev URL.

How do I debug connection issues?

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

What runtime dependencies are required?

Node.js, npm, a Cloudflare account, and the Cloudflare Workers CLI (wrangler). The project uses Nx for local development and mcp-remote for client proxying.
