Frequently asked questions

1

What runtime and dependencies are required?

Node.js and npm are needed for local development. A Cloudflare account and Wrangler CLI are required for deployment.

2

How does authentication work?

The server uses OAuth login. When connecting via MCP Inspector or Claude Desktop, a browser window opens for user/password login (mock login in local development).

3

What transport protocol does the server use?

It uses SSE (Server-Sent Events) as the MCP transport, accessed via the `/sse` endpoint.

4

How can I debug connection issues?

Run `npx mcp-remote http://localhost:8787/sse` to test direct CLI connection. Restart Claude or clear `~/.mcp-auth` if needed.

5

Where are OAuth data stored?

OAuth tokens are stored in a Cloudflare KV namespace (`OAUTH_KV`), created during deployment setup.
