FAQ from Remote MCP Server on Cloudflare
How do I run the server locally?
Clone the repo, run npm install, then npx nx dev remote-mcp-server. Access it at http://localhost:8787/.
How do I connect the MCP Inspector to my local server?
Start the inspector with npx @modelcontextprotocol/inspector, set Transport Type to SSE, enter http://localhost:8787/sse, and click Connect. You’ll be presented with a mock login screen.
How do I connect Claude Desktop to the remote server?
Update Claude’s config file to add an MCP server entry with command: "npx", args: ["mcp-remote", "https://your-worker.your-account.workers.dev/sse"]. Claude will open a browser for OAuth login.
How do I deploy the server to Cloudflare?
Create a KV namespace with npx wrangler kv namespace create OAUTH_KV, add the namespace ID to wrangler.jsonc, then run npm run deploy. Your server will be available at a workers.dev URL.
What debugging steps are recommended?
Restart Claude, or test connectivity directly using npx mcp-remote http://localhost:8787/sse. In rare cases, clear cached auth files with rm -rf ~/.mcp-auth.
