3. Environment Configuration

Update wrangler.jsonc with your configuration:

{
  "vars": {
    "GOOGLE_CLIENT_ID": "your-google-client-id",
    "GOOGLE_CLIENT_SECRET": "your-google-client-secret",
    "COOKIE_ENCRYPTION_KEY": "your-32-byte-base64-key",
    "GOOGLE_DRIVE_FOLDER_ID": "your-shared-folder-id",
    "GOOGLE_CALENDAR_ID": "primary"
  }
}

4. Get Your Google Drive Folder ID

1. Open Google Drive in your browser
2. Navigate to your shared meetings folder
3. The folder ID is the last part of the URL: https://drive.google.com/drive/folders/FOLDER_ID_HERE

5. Deploy to Cloudflare Workers

Usage with Claude Desktop

1. Add the MCP server to your Claude Desktop configuration:

{
  "mcpServers": {
    "meetings": {
      "command": "node",
      "args": ["path/to/google-services-mcp"],
      "env": {
        "GOOGLE_CLIENT_ID": "your-client-id",
        "GOOGLE_CLIENT_SECRET": "your-client-secret"
      }
    }
  }
}

2. Restart Claude Desktop
3. The meeting tools will be available in your Claude conversations

API Rate Limits & Caching

The server implements intelligent caching to minimize API calls:

• File Lists: 5 minutes TTL
• File Content: 1 hour TTL
• Calendar Events: 5 minutes TTL
• File Metadata: 10 minutes TTL

Security Considerations

• All API operations use read-only scopes
• OAuth tokens are securely stored and encrypted
• No ability to modify documents or calendar events
• All API calls are logged for audit purposes

Contributing

1. Fork the repository
2. Create a feature branch: git checkout -b feature/amazing-feature
3. Commit your changes: git commit -m 'Add amazing feature'
4. Push to the branch: git push origin feature/amazing-feature
5. Open a Pull Request

Deployment

Automatic Deployment

The project includes a GitHub Actions workflow that automatically deploys to Cloudflare Workers when you push to the main branch.

Required GitHub Secrets:

• CLOUDFLARE_API_TOKEN: Your Cloudflare API token
• CLOUDFLARE_ACCOUNT_ID: Your Cloudflare account ID

Manual Deployment

npm run deploy

Troubleshooting

Common Issues

1. OAuth Redirect URI Mismatch

   • Ensure your redirect URI in Google Cloud Console matches your worker domain
   • Format: https://your-worker.workers.dev/callback

2. Folder Not Found

   • Verify your GOOGLE_DRIVE_FOLDER_ID is correct
   • Ensure the service account has access to the folder

3. API Rate Limits

   • The server implements caching to minimize API calls
   • If you hit rate limits, increase cache TTL values

4. Authentication Issues

   • Re-authenticate if you've changed OAuth scopes
   • Check that all required APIs are enabled in Google Cloud Console

Debug Mode

For local development, you can enable debug logging by setting:

export DEBUG=google-services-mcp:*
