Google Workspace MCP Server

Your own MCP server for full Google Workspace access from Claude Desktop or Claude Code.

Gmail (send + read) · Drive · Calendar · Docs · Sheets · Slides · Forms · Tasks · Contacts

Built with FastMCP. Uses your own Google Cloud OAuth credentials. You own everything.

Setup

1. Google Cloud Console (you do this in your browser)

1. Go to https://console.cloud.google.com → Create a new project

2. Enable these APIs (APIs & Services → Library):

   • Gmail, Calendar, Drive, Docs, Sheets, Slides, Forms, Tasks, People, Google Meet

3. Set up OAuth consent screen (APIs & Services → OAuth consent screen):

   • Choose External, add your email as test user

   • Add all workspace scopes

4. Create OAuth credentials (APIs & Services → Credentials → Create → OAuth Client ID → Desktop Application)

5. Copy the Client ID and Client Secret

2. Install & Run

# Set your credentials
export GOOGLE_OAUTH_CLIENT_ID="your-client-id-here"
export GOOGLE_OAUTH_CLIENT_SECRET="your-client-secret-here"

# Run with uv (no install needed)
cd google-workspace-mcp
uv run server.py

3. Connect to Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "google_workspace": {
      "command": "uv",
      "args": ["run", "--directory", "/path/to/google-workspace-mcp", "server.py"],
      "env": {
        "GOOGLE_OAUTH_CLIENT_ID": "your-client-id",
        "GOOGLE_OAUTH_CLIENT_SECRET": "your-client-secret"
      }
    }
  }
}

4. Connect to Claude Code

claude mcp add google_workspace -- uv run --directory /path/to/google-workspace-mcp server.py

5. First authentication

First time you use any tool, a browser window opens for Google OAuth. Sign in, approve the permissions, done. Token is saved to ~/.gw-mcp/token.json and auto-refreshes.

Build It Yourself Prompt

Want to rebuild this from scratch using Claude? Paste this into Claude Code Desktop:

Build me a Python MCP server using FastMCP at ~/Desktop/google-workspace-mcp/. It should give me full access to Google Workspace with these tools:

Calendar (8): list calendars, get events (with time range + search), create event (with attendees, timezone, Google Meet link generation), update event, delete event, query free/busy, list recurring event instances, quick add from text string

Meet (7): create meeting space, get meeting space, list participants, get artifacts (recordings + transcripts), end active conference, list conference records, list participant sessions

Drive (15): search files, read file content (export Google Docs/Sheets/Slides to text), create file (plain text or Google Doc), list folder, share file, create folder, copy file, export to format, add comment, list comments, list revisions, list permissions, delete permission, trash, untrash

Docs (9): create, read, insert text at position, find and replace, append text, insert table, insert image, format text (bold/italic/color/font), insert bullet list, insert page break

Sheets (12): read ranges, write values, append rows, create spreadsheet, clear ranges, get spreadsheet metadata, batch update cells, add sheet/tab, delete sheet/tab, merge cells, add chart, add conditional formatting, add named range

Tasks (8): list task lists, list tasks, create task (with subtask support), update task, delete task, create task list, move/reorder task, clear completed tasks

Requirements:

• Separate file per service (tools_gmail.py, tools_calendar.py, tools_meet.py, tools_drive.py, tools_docs.py, tools_sheets.py, tools_tasks.py, tools_contacts.py, tools_slides.py, tools_forms.py) plus auth.py and server.py

• auth.py handles Google OAuth2: reads GOOGLE_OAUTH_CLIENT_ID and GOOGLE_OAUTH_CLIENT_SECRET from env vars, opens browser on first use, saves token to ~/.gw-mcp/token.json, auto-refreshes

• Use google-api-python-client and google-auth-oauthlib

• pyproject.toml with uv, entry point gw-mcp = "server:main"

• .gitignore for .venv, pycache, .env, token.json, credentials.json

• README with setup instructions for Google Cloud Console, running with uv, and adding to Claude Desktop + Claude Code configs
