gamcp 0.1.3

An MCP server to interact with GAM7 for Google Workspace administration

GAM MCP Server

This is a Model Context Protocol (MCP) server that empowers an AI IDE, terminal, or agent to perform administrative actions on Google Workspace using an existing local installation of GAM7.

Prerequisites

• Python 3.10+ (managed via uv or installed globally)
• GAM7: Installed and fully authenticated with a client_secrets.json and oauth2.txt/oauth2service.json.
• uv: The ultra-fast Python package installer and resolver.

Environment Variables

The server relies on the following environment variables to locate and run your local GAM installation:

• GAM_EXECUTABLE_PATH (optional): The absolute path to your local gam executable. If gam is already in your PATH, you can leave this unset, and the server will execute gam directly.
• GAM_CFG_DIR (optional): The absolute path to the directory containing your GAM configuration and authentication files (e.g. oauth2.txt, client_secrets.json). If left unset, GAM will use its default configuration paths.

Installation and Usage

To run the server with uv:

uv run src/gamcp/server.py

Usage with Claude Desktop, Gemini Enterprise, or other MCP clients

Add the following to your claude_desktop_config.json:

Important: Claude Desktop often does not inherit your full system path. If you used the standalone installer for uv (which places it in ~/.local/bin or ~/.cargo/bin), you will likely receive a "Failed to spawn process" error. To fix this, replace "uv" or "uvx" in the command field with the absolute path to the executable (e.g., "/Users/YOUR_USER/.local/bin/uvx" or "/opt/homebrew/bin/uvx").

Running locally (Development & Cloning)

If you've cloned this repository locally, you can use uv run:

{
  "mcpServers": {
    "gamcp": {
      "command": "/absolute/path/to/uv",
      "args": [
        "--directory",
        "/absolute/path/to/gamcp",
        "run",
        "src/gamcp/server.py"
      ]
    }
  }
}

Easy installation (Global standard)

If you have published this package to PyPI or installed it globally via uv tool install, you can use uvx directly, which runs isolated tools reliably.

{
  "mcpServers": {
    "gamcp": {
      "command": "/absolute/path_to/.local/bin/uvx",
      "args": [
        "gamcp"
      ]
    }
  }
}

Note: In most cases, the MCP server will automatically detect the standard location GAM or GAMADV-XTD3 installers place their configuration and executable files into. If you installed GAM in a non-standard location, you can additionally supply the GAM_EXECUTABLE_PATH or GAM_CFG_DIR variables in the env dictionary block.

Tools

The server exposes a comprehensive suite of tools organized by functional area:

Core Operations

• run_gam_command(args: list[str]): Executes raw GAM commands. Provide arguments as a list of strings (e.g., ["info", "domain"]). Returns standard output and standard error.
• validate_gam_command(args: list[str]): Validates the structure of a proposed GAM command without executing it.

Bulk Processing

• build_bulk_gam_command(...): Constructs a GAM bulk processing command from structured inputs without executing it.
• bulk_process_from_sheet(...): Executes a GAM bulk command using a Google Sheet as the data source.

Google Drive

• migrate_folder_to_shared_drive(...): Migrates a Google Drive folder to a Shared Drive.
• get_permissions_to_sheet(...): Retrieves file/folder/shared drive permissions and writes them to a Google Sheet.

Calendar

• transfer_calendar_event(...): Transfers a calendar event from one user to another.

Groups

• create_collaborative_inbox_group(...): Creates a new Google Group configured as a Collaborative Inbox.
• get_group_permissions_to_sheet(...): Retrieves group members and their roles, outputting to a Google Sheet.

Users

• create_gws_user(...): Creates a new Google Workspace user.
• identify_workspace_entity(identifier: str): Identifies a Workspace entity (user, group, alias, etc.) by its email or ID.

Reports

• get_gmail_log_events(...): Retrieves Gmail log events and optionally writes them to a Google Sheet.
• get_user_email_count_to_sheet(...): Retrieves email counts for specific labels across multiple users.

Resources

The server provides the following resources:

• gam://bulk-processing-guide: A reference guide for constructing GAM bulk processing commands. Includes details on source types, processing modes, column substitution syntax, and batch file directives.
