Manual Installation

1. Prerequisites:

   • Install Bun:

   brew install oven-sh/bun/bun  # macOS/Linux with Homebrew
   

2. Set Up OAuth:

   • Create a Google Cloud project in the Google Cloud Console.
   • Set up OAuth 2.0 credentials (Client ID, Client Secret).
   • Choose the type Desktop app.
   • If using test mode, add your email to the test users list.
   • Make sure to enable API access for desired services (Gmail, Calendar, Drive etc.).

3. Configure Your Client: Edit your claude_desktop_config.json (or equivalent config file for your client):

{
  "mcpServers": {
    "google-mcp": {
      "command": "bunx",
      "args": ["--no-cache", "google-mcp@latest"],
      "env": {
        // Either can be used, but not both
        // Use OAuth
        "GOOGLE_OAUTH_CLIENT_ID": "<YOUR_CLIENT_ID>",
        "GOOGLE_OAUTH_CLIENT_SECRET": "<YOUR_CLIENT_SECRET>",
        "GOOGLE_OAUTH_TOKEN_PATH": "<PATH_TO_STORE_TOKENS>",
        // Use Service Account
        "GOOGLE_CLIENT_EMAIL": "<YOUR_SERVICE_ACCOUNT_EMAIL>",
        "GOOGLE_PRIVATE_KEY": "<YOUR_SERVICE_ACCOUNT_PRIVATE_KEY>",
        "GMAIL_USER_TO_IMPERSONATE": "<USER_TO_IMPERSONATE>"
      }
    }
  }
}

4. Authenticate:
   • The first time you run the server, it will open a browser for OAuth authentication. Follow the prompts to grant access, and tokens will be saved to GOOGLE_OAUTH_TOKEN_PATH.

Usage

Now, ask Claude to use the google-mcp tool.

Send an email to [email protected] with the subject "Meeting Notes" and body "Here are the notes from today."

List my upcoming calendar events for the next 3 days.

Create a calendar event titled "Team Sync" tomorrow at 10 AM for 1 hour.
