🚀 Setup

1. Google Sheets API Setup

1. Create a Google Cloud project or use an existing one
2. Enable the Google Sheets API
3. Configure an OAuth consent screen
   • Select "External" for testing purposes
   • Add your email as a test user
4. Add OAuth scope: https://www.googleapis.com/auth/spreadsheets
5. Create OAuth 2.0 Client ID credentials
   • Choose "Desktop Application"
6. Download the credentials JSON file
7. Save it securely and note the file path

2. Installation

Using uv (recommended):

cd sheets-mcp-server
uv sync

3. Authentication

On first run, the server will launch a browser for OAuth authentication. Access tokens will be saved to the specified --token-path for future use.
