Frequently asked questions

How do I run the MCP server locally?

How do I connect the MCP Inspector to the server?

Start the inspector with `npx @modelcontextprotocol/inspector`, switch Transport Type to SSE, enter `http://localhost:8787/sse` (or your deployed URL) as the URL, and click Connect. You will be prompted to log in.

How do I connect Claude Desktop to the server?

Add an `mcpServers` entry to Claude Desktop’s config file using `npx mcp-remote` as the command and your server’s SSE URL (e.g., `http://localhost:8787/sse` locally or your `workers.dev` URL) as an argument, then restart Claude.

Create an `OAUTH_KV` namespace with `npx wrangler kv namespace create OAUTH_KV`, add its ID to `wrangler.jsonc`, then run `npm run deploy`.

How do I debug connection issues?

Restart Claude, or test directly from the command line with `npx mcp-remote http://localhost:8787/sse`. In rare cases, clear the files in `~/.mcp-auth` with `rm -rf ~/.mcp-auth`.
