gworkspace-mcp

Model Context Protocol server for Google Workspace automation: Google Sheets, Apps Script, Drive, Docs, Gmail, and triggers. Built with FastMCP.

Designed to be used from Claude Code (or any MCP-compatible client) so you can edit Apps Script projects, manipulate spreadsheets, send emails and manage Drive files directly from a conversation.

Features

  • Apps Script (9 tools) — list, read, update, create, deploy and run Apps Script projects. Granular file edits so you don't have to rewrite entire scripts.

  • Sheets (10 tools) — read/write ranges, batch updates, formatting, protection, formulas, dashboards.

  • Drive (4 tools) — list, search, move and manage files.

  • Docs (1 tool) — read/edit Google Docs.

  • Gmail (3 tools) — compose and send email.

  • Triggers (3 tools) — manage Apps Script time-based and event triggers.

  • Connect (1 tool) — bind a local Apps Script project to a spreadsheet.

Requirements

  • Python 3.10+

  • A Google Cloud project with the following APIs enabled:

    • Google Sheets API

    • Google Drive API

    • Apps Script API

    • Google Docs API

    • Gmail API

    • Google Calendar API

  • OAuth 2.0 Desktop credentials (client_secret.json)

Installation

git clone https://github.com/LeooNic/gworkspace-mcp.git
cd gworkspace-mcp
pip install -e .

Or with uv:

uv pip install -e .

Google Cloud setup

  1. Go to console.cloud.google.com and create a project.

  2. Enable the APIs listed above under APIs & Services → Library.

  3. Go to APIs & Services → OAuth consent screen, configure it as External, and add your Google account as a test user.

  4. Go to APIs & Services → Credentials → Create Credentials → OAuth client ID, choose Desktop app, and download the JSON.

  5. Make the credentials available to the server in one of these ways:

    • Place the JSON at ~/.secrets/gworkspace-mcp/client_secret.json, or

    • Set GOOGLE_CLIENT_SECRET_PATH=/full/path/to/client_secret.json, or

    • Set GOOGLE_OAUTH_CLIENT_ID and GOOGLE_OAUTH_CLIENT_SECRET as env vars.

The first time a tool runs, a browser window will open for OAuth consent. The resulting token is stored at ~/.secrets/gworkspace-mcp/token.json and refreshed automatically.

Register with Claude Code

Add this to your Claude Code settings.json (or ~/.claude.json):

{
  "mcpServers": {
    "gworkspace": {
      "command": "gworkspace-mcp"
    }
  }
}

If gworkspace-mcp is not on your PATH, use the absolute path to the executable created by pip install -e . (on Windows, typically C:\Users\<you>\AppData\Local\Programs\Python\Python3XX\Scripts\gworkspace-mcp.exe).

Alternative invocation without installing the entry point:

{
  "mcpServers": {
    "gworkspace": {
      "command": "python",
      "args": ["-m", "gworkspace_mcp.server"]
    }
  }
}

OAuth scopes

The server requests the following scopes:

  • spreadsheets, drive, documents, calendar

  • script.projects, script.deployments, script.processes, script.metrics

  • gmail.send, gmail.compose

  • userinfo.email, userinfo.profile

Security notes

  • Your client_secret.json and token.json are personal — never commit them. The repo .gitignore already excludes them.

  • Tokens live under ~/.secrets/gworkspace-mcp/.

  • The server runs locally; it does not expose any network endpoint.

    TDQS

    B3.3/5.0

    Scored across 31 tools

    Disambiguation4/5

    Most tools have distinct purposes, but some overlap exists. For example, send_email and send_html_email could be confused, and drive_copy/drive_move have similar file manipulation functions. However, clear descriptions help differentiate them.

    Naming Consistency5/5

    Tool names follow a consistent snake_case pattern with clear verb_noun conventions. Drive tools use drive_ prefix, script tools use script_ prefix, sheets tools use sheets_ prefix, and email/trigger/workspace tools follow similar patterns. No mixing of conventions.

    Tool Count2/5

    31 tools is excessive for a single MCP server. While the domain (Google Workspace automation) is broad, this feels like multiple servers combined. A more focused scope with 15-20 tools would be more manageable for agents.

    Completeness5/5

    The tool surface provides comprehensive coverage for Google Workspace automation. It includes full CRUD operations for Drive files, Sheets manipulation, Apps Script development, email sending, and trigger management. The workspace_connect tool provides excellent discovery capabilities.
