Frequently asked questions

What runtime dependencies does the server require?

Node.js and npm are needed for local development. For deployment, the Cloudflare Wrangler CLI is used; a Cloudflare account is implied for publishing the Worker.

How do I connect Claude Desktop to the remote server?

Update your Claude Desktop configuration file to use `npx mcp-remote` with the server’s `workers.dev/sse` URL as the argument.

How can I debug connectivity issues?

Restart Claude Desktop, or test the server directly with `npx mcp-remote http://localhost:8787/sse`. In rare cases, clear the `~/.mcp-auth` directory.

What transport protocol does the server use?

The server communicates over Server-Sent Events (SSE). Clients must connect to the `/sse` endpoint.

Is the server limited to local or remote use only?

It can be run both locally (for development) and deployed to Cloudflare Workers for remote access via the internet.
