Frequently asked questions

What is needed to run the server locally?

Clone the repo, install dependencies with `npm install`, and run `npx nx dev remote-mcp-server`. The server will be available at `http://localhost:8787/`.

How do I connect Claude Desktop to the remote server?

In Claude Desktop’s config file, add an MCP server entry with command `npx`, args `["mcp-remote", "https://your-worker.workers.dev/sse"]`. Restart Claude.

How do I deploy the server to Cloudflare?

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.

What transport does the MCP server use?

It uses SSE (Server-Sent Events) – the endpoint is `/sse` on the server URL.

How can I debug connection issues?

Restart Claude, or test directly with `npx mcp-remote http://localhost:8787/sse`. Clearing `~/.mcp-auth` may help in rare cases.
