📦 Installation

This project can be installed for local development and testing as follows:

1. Clone Repository:

   git clone <REPOSITORY_URL>
   cd mcp-google-workspace
   

2. Create and Activate Virtual Environment (Recommended):

   python -m venv .venv
   source .venv/bin/activate  # macOS/Linux
   # .venv\Scripts\activate   # Windows
   

3. Install Dependencies and Project (Editable Mode): Use uv (recommended) or pip to install.

   # Using uv
   uv pip install -e .
   
   # Using pip
   pip install -e .
   

   The -e . option installs the project in "editable" mode, so changes to the source code are immediately reflected.

Google API Setup

Google Cloud Console Configuration

1. Create a new project in the Google Cloud Console.
2. Enable the following APIs:
   • Google Sheets API
   • Google Docs API
   • Google Drive API

Create OAuth Credentials

1. Go to "APIs & Services" → "Credentials".
2. Click "Create Credentials" → "OAuth client ID".
3. Select Application type: "Desktop app".
4. Save the generated JSON file as credentials.json in the project root.

Configure OAuth Consent Screen

1. Go to "APIs & Services" → "OAuth consent screen".
2. Select User Type: "External".
3. Fill in the required information.
4. Add Scopes:
   • https://www.googleapis.com/auth/spreadsheets
   • https://www.googleapis.com/auth/documents
   • https://www.googleapis.com/auth/drive.file
5. Add your email to "Test users".

🔧 Usage

If the project is installed in editable mode (-e .), you can run the MCP server using the script defined in pyproject.toml:

# Run while the virtual environment is activated
mcp-google-workspace

Alternatively, you can run it as a Python module from the project root directory:

python -m src.mcp_google_workspace.server

Using with Claude Desktop

Add the following configuration to your mcp_config.json file (the filename might vary, e.g., mcp.json or mcp_servers.json depending on your environment):

{
  "mcpServers": {
    "google-workspace": {
      "command": "mcp-google-workspace",
      "env": {
        "CREDENTIALS_PATH": "/path/to/your/credentials.json",
        "TOKEN_PATH": "/path/to/your/token.json"
      }
    }
  }
}

Environment Variables

• CREDENTIALS_PATH: Path to the OAuth credentials file (defaults to credentials.json in the workspace root).
• TOKEN_PATH: Path to the token storage file (defaults to token.json in the workspace root).
• DRIVE_FOLDER_ID: Specific Google Drive folder ID to work with (optional; if not specified, searches the entire Drive).

(Note: SERVICE_ACCOUNT_PATH is not used in this implementation as it currently uses the OAuth 2.0 user authentication flow.)
