FAQ from Remote MCP Server on Cloudflare
How do I connect the MCP Inspector?
Open the MCP Inspector, switch Transport Type to SSE, enter http://localhost:8787/sse (or your deployed URL with /sse), and click "Connect". You will be redirected to a (mock) login screen; input any email and password to log in.
How do I connect Claude Desktop to my server?
Add a configuration entry in Claude Desktop’s settings file. Use npx mcp-remote as the command and your server’s URL with /sse as an argument (e.g., "args": ["mcp-remote", "http://localhost:8787/sse"]). Restart Claude Desktop; a browser window will open for OAuth login.
How do I deploy the server to Cloudflare?
Create a KV namespace with npx wrangler kv namespace create OAUTH_KV, copy the returned ID into wrangler.jsonc, then run npm run deploy. The server will be available at your workers.dev URL.
What debugging tips are available?
Restart Claude Desktop if connections fail. Test directly from the command line using npx mcp-remote http://localhost:8787/sse. In rare cases, clear authentication files with rm -rf ~/.mcp-auth.
Does the server support OAuth authentication?
Yes, the server includes OAuth login. On first connection, clients (Inspector or Claude Desktop) are redirected to a login screen. For local development, a mock login accepts any email and password.
