Frequently asked questions

How do I develop locally?

Clone the repo, run `npm install`, then `npx nx dev remote-mcp-server`. The server will be available 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”. A mock login screen appears; input any email and password.

How do I connect Claude Desktop to my local server?

Add the following to Claude’s `mcpServers` config: `"command": "npx", "args": ["mcp-remote", "http://localhost:8787/sse"]`. Restart Claude; a browser window will open for login.

How do I deploy to Cloudflare?

Run `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.

How do I connect a remote MCP client after deployment?

Use the MCP Inspector or Claude Desktop with the URL `https://your-worker.your-account.workers.dev/sse`. For Claude, set `"args": ["mcp-remote", "https://your-worker.your-account.workers.dev/sse"]`.
