Quickstart

Oauth 2

Google Workspace (G Suite) APIs require OAuth2 authorization. Follow these steps to set up authentication:

1. Create OAuth2 Credentials:

• Go to the Google Cloud Console
• Create a new project or select an existing one
• Enable the Gmail API and Google Calendar API for your project
• Go to "Credentials" → "Create Credentials" → "OAuth client ID"
• Select "Desktop app" or "Web application" as the application type
• Configure the OAuth consent screen with required information
• Add authorized redirect URIs (include http://localhost:4100/code for local development)

1. Required OAuth2 Scopes:

[
     "openid",
     "https://mail.google.com/",
     "https://www.googleapis.com/auth/calendar",
     "https://www.googleapis.com/auth/userinfo.email"
   ]

1. Then create a .gauth.json in your working directory with client

{
    "web": {
        "client_id": "$your_client_id",
        "client_secret": "$your_client_secret",
        "redirect_uris": ["http://localhost:4100/code"],
        "auth_uri": "https://accounts.google.com/o/oauth2/auth",
        "token_uri": "https://oauth2.googleapis.com/token"
    }
}

1. Create a .accounts.json file with account information

{
    "accounts": [
        {
            "email": "alice@bob.com",
            "account_type": "personal",
            "extra_info": "Additional info that you want to tell Claude: E.g. 'Contains Family Calendar'"
        }
    ]
}

You can specifiy multiple accounts. Make sure they have access in your Google Auth app. The extra_info field is especially interesting as you can add info here that you want to tell the AI about the account (e.g. whether it has a specific agenda)

Note: When you first execute one of the tools for a specific account, a browser will open, redirect you to Google and ask for your credentials, scope, etc. After a successful login, it stores the credentials in a local file called .oauth.{email}.json . Once you are authorized, the refresh token will be used.
