FAQ from Remote MCP Server on Cloudflare

How do I develop locally?

Clone the repository, run npm install, then npx nx dev remote-mcp-server. Open http://localhost:8787/ in your browser.

How do I connect the MCP Inspector to my local server?

Start the inspector with npx @modelcontextprotocol/inspector, switch Transport Type to SSE, and enter http://localhost:8787/sse as the URL. Log in with any email and password on the mock login screen.

How do I deploy to Cloudflare?

First create a KV namespace with npx wrangler kv namespace create OAUTH_KV and add its ID to wrangler.jsonc. Then run npm run deploy.

How do I connect Claude Desktop to a remote server?

Update your Claude Desktop config file to use mcp-remote with the full workers.dev URL (e.g., https://worker-name.account-name.workers.dev/sse). Restart Claude; a browser window will open for OAuth login.

What should I do if something goes wrong?

Try restarting Claude, or test the connection directly on the command line with npx mcp-remote http://localhost:8787/sse. In rare cases, clear the credentials by running rm -rf ~/.mcp-auth.
