Frequently asked questions

What authentication method does it require?

It uses OAuth 2.0 with a desktop application client. You must create a client in Google Cloud Console and place the resulting `credentials.json` file in the server's root directory.

What are the runtime requirements?

The server is run using `npx ts-node`, so Node.js and TypeScript support are required.

Where does the OAuth callback go?

The redirect URI must be set to `http://localhost:3000/callback` in the credentials file.

How do I configure it for Claude Desktop?

Edit `claude_desktop_config.json` to add a `calendar` MCP server entry using the `npx ts-node` command with paths to the project's `tsconfig.json` and `src/index.ts`.

What transport or protocol does it use?

The README does not specify the transport layer; it only describes the MCP server setup for Claude Desktop.
