Overview

Google Workspace MCP Server

Google Workspace MCP Server gives an AI assistant 120+ tools across all twelve major Google Workspace services - Gmail, Drive, Calendar, Docs, Sheets, Slides, Forms, Tasks, Contacts, Chat, Custom Search, and Apps Script - with multi-user OAuth 2.1 auth and progressive tool tiers to keep context lean. Use it when an AI assistant needs deep, fine-grained access to real Google Workspace data across many services, ideally hosted centrally for an organization. Only connect trusted data, since emails and documents can carry hidden prompt-injection instructions.

What it does

Google Workspace MCP Server gives an AI assistant natural-language control over all twelve major Google Workspace services - Gmail, Drive, Calendar, Docs, Sheets, Slides, Forms, Tasks, Contacts, Chat, Custom Search, and Apps Script - through 120+ tools behind a single MCP server. It supports multi-user OAuth 2.1 auth, fine-grained per-service editing tools, and both legacy stdio and streamable-HTTP transports, plus a standalone CLI and a "Code Mode" for coding agents like Claude Code and Codex.

When to use - and when NOT to

Use it when an AI assistant needs deep, fine-grained access to a real Google Workspace account or organization - searching and sending Gmail with labels and filters, editing Docs tables and comments, building Sheets with conditional formatting, or writing and deploying Apps Script - rather than the narrower built-in Google integrations some clients ship with. Its native OAuth 2.1 support, stateless deployment mode, and external-auth-server passthrough are specifically built so an organization can host one instance centrally rather than every user running their own; it works with any free Google account or Workspace plan, from Starter through Enterprise and Non Profit. Prompt injection is a real risk with this much access - emails, docs, and calendar events can carry hidden instructions - so only connect trusted data and be deliberate about which write tools are enabled.

Capabilities

Tool coverage per service: Gmail (15 tools - search, send, draft, labels, filters, attachments), Drive (16 - search, create, share, import Office files), Calendar (7 - events, free/busy, Out of Office, Focus Time), Docs (19 - editing, styling, tables, tabs, comments, export), Sheets (14 - ranges, tables, formatting, conditional rules), Slides (7), Forms (6), Tasks (6), Contacts (8), Chat (6, requiring one-time Chat app setup on a Workspace account), Custom Search (2), and Apps Script (15 - write, deploy, run, and debug scripts). Three progressive tool tiers - core, extended, complete - keep context windows lean, combinable with --tools <service>, --read-only, or --disabled-tools. By default the server sends data only to Google's own APIs using your own OAuth client, with no usage reporting or telemetry; local file reads are sandboxed to a managed attachment directory, and paths like .env*, ~/.ssh/, and ~/.aws/ are always blocked even if the allowed-directory list is broadened.

How to install

export GOOGLE_OAUTH_CLIENT_ID="..."
export GOOGLE_OAUTH_CLIENT_SECRET="..."
uvx workspace-mcp --tool-tier core

For OAuth 2.1 with PKCE, required for remote or shared HTTP endpoints, set MCP_ENABLE_OAUTH21=true and launch with --transport streamable-http. Claude Desktop, web, and mobile connect over HTTP as a Connector; Claude Code adds it via claude mcp add --transport http workspace-mcp http://localhost:8000/mcp; ChatGPT connects through Developer Mode. A companion CLI, workspace-cli, calls tools against a running server with encrypted, disk-backed token caching, installed with uv tool install . (the same-named package on PyPI via uvx is unrelated and abandoned). Deployment options include stateless container mode with zero disk writes, service accounts with domain-wide delegation, Valkey/Redis-backed OAuth proxy storage for distributed setups, and Docker.

Who it's for

Organizations and power users who want one centrally hosted, deeply capable Google Workspace connector across every major service, rather than per-user setups or the narrower Workspace integrations built into some AI clients. It is MIT-licensed with no CLA or copyleft dependencies.

Website

Full natural language control over Google Calendar, Drive, Gmail, Docs, Sheets, Slides, Forms, Tasks, Contacts, and Chat through all MCP clients, AI assistants and developer tools.
Includes a full featured CLI & Code Mode for use with tools like Claude Code and Codex!

The most feature-complete Google Workspace MCP server, it can do things that Google's own tooling and the built in integrations with Claude and ChatGPT can't come close to. With multi-user support, rich fine-grained editing tools and the most extensive coverage of any Google Workspace tool in existence, Workspace MCP is in a different class.

By leveraging native OAuth 2.1, stateless deployment capability and external auth server & gateway passthrough auth support, it's also the only Workspace MCP you can host for your whole organization centrally & securely!

What It Does

Workspace MCP connects AI assistants to all twelve major Google Workspace services - 120+ tools behind a single MCP server, with OAuth 2.1 multi-user auth, three progressive tool tiers, read-only mode, a full CLI, and stateless container deployment. It runs locally over stdio for legacy clients and remotely over streamable HTTP with full implementation of the latest MCP spec.

The README covers just enough to get you running, with extensive documentation on the website:

Security & Compliance

For Security Teams

By default, this server sends no data anywhere except Google's APIs, on behalf of the authenticated user, using your own OAuth client credentials. There is no usage reporting, analytics, license server, or SaaS dependency outside optional OTel support for your own usage.

  • Fully open source - every line is auditable in this repo
  • Your OAuth client, your GCP project - credentials never leave your environment & you control scopes
  • You control the network - deploy behind your reverse proxy, in your VPC, on your own terms
  • Stateless mode - zero disk writes for locked-down container environments
  • Sensitive path blocking - local file reads default to the managed attachment directory, and validate_file_path() still blocks .env* files plus common home-directory credential stores such as ~/.ssh/ and ~/.aws/ even if ALLOWED_FILE_DIRS is broadened

Full dependency tree in pyproject.toml, pinned in uv.lock.

For Legal & Procurement

This project is MIT licensed - not "open core," not "source available," not "free with a CLA." There is no dual licensing, no commercial tier gating features, and no contributor license agreement.

  • Use commercially without restriction - build products, sell services, deploy internally
  • Fork, embed, redistribute - MIT requires only attribution
  • No CLA - contributions remain under MIT
  • No built-in telemetry to disclose - optional tracing is off unless you configure it
  • No network effects - the server never contacts any endpoint you didn't configure
  • Standard dependency licenses - MIT, Apache 2.0, and BSD throughout the dependency chain; no copyleft, no AGPL

Quick Start

Set credentials → pick a launch command → connect your client. Full walkthrough with screenshots: workspacemcp.com/quick-start

You'll need an OAuth client from Google Cloud Console with the APIs enabled for the services you plan to use - the quick start guide walks through it in about five minutes.

Confidential Client

# 1. Credentials
export GOOGLE_OAUTH_CLIENT_ID="..."
export GOOGLE_OAUTH_CLIENT_SECRET="..."

# 2. Launch - pick a tier
uvx workspace-mcp --tool-tier core       # essential tools
uvx workspace-mcp --tool-tier extended   # core + management ops
uvx workspace-mcp --tool-tier complete   # everything

# Or cherry-pick services
uvx workspace-mcp --tools gmail drive calendar

OAuth 2.1 (PKCE)

# 1. Credentials - MCP clients connect with PKCE and no
#    secret, but Google still requires one server-side
export MCP_ENABLE_OAUTH21=true
export GOOGLE_OAUTH_CLIENT_ID="..."
export GOOGLE_OAUTH_CLIENT_SECRET="..."
export WORKSPACE_MCP_PORT=8000
export GOOGLE_OAUTH_REDIRECT_URI="http://localhost:${WORKSPACE_MCP_PORT}/oauth2callback"
export OAUTHLIB_INSECURE_TRANSPORT=1

# 2. Launch - OAuth 2.1 requires HTTP transport
uvx workspace-mcp --transport streamable-http --tool-tier core

Tool tiers keep context windows lean: core is the essential set, extended adds management operations, complete loads everything. Combine with --tools <service> ..., --read-only, or per-service --permissions, and subtract individual tools with --disabled-tools <name> ... - details in the server modes docs.

Connect Your Client

Claude Desktop, web & mobile - run the server in HTTP mode and add it as a Connector (Settings → Connectors → Add custom connector). This is the recommended path; the Connector guide has step-by-step screenshots. Legacy stdio configuration remains available for clients without Connector support - see the FAQ.

Claude Code

# Start the server in HTTP mode, then:
claude mcp add --transport http workspace-mcp http://localhost:8000/mcp

# Optional: install the bundled skill for better Workspace tool routing
ln -s "$(pwd)/skills/managing-google-workspace" ~/.claude/skills/managing-google-workspace

ChatGPT - connect via Developer Mode with the ChatGPT guide.

VS Code, LM Studio, Open WebUI, and everything else - any MCP client works over streamable HTTP (recommended) or stdio. Client-specific walkthroughs live in the guides and FAQ.

CLI

workspace-cli lists and calls tools against a running server with encrypted, disk-backed OAuth token caching - authenticate once, script forever:

uv run workspace-cli list
uv run workspace-cli call search_gmail_messages query="is:unread" max_results=5

Install globally with uv tool install . from this repo. ⚠️ Don't use uvx workspace-cli - an abandoned PyPI package squats that name.

Deployment & Advanced Configuration

Everything you need to run this in production lives in two places. The documentation covers auth modes and server configuration:

The Advanced Deployment guide covers self-hosting specifics: reverse proxy setup with WORKSPACE_EXTERNAL_URL (including the nginx Origin: null consent workaround, the WORKSPACE_MCP_ALLOW_NULL_ORIGIN_CONSENT escape hatch, and the Referrer-Policy pitfall), origin validation and VS Code webview allowlisting, credential store backends (local directory or GCS with CMEK enforcement), and the complete environment variable reference.

Security Best Practices

By default this server sends no data anywhere except Google's APIs, using your own OAuth client credentials - no usage reporting, analytics, license server, or SaaS dependency. MIT licensed with no CLA, no dual licensing, and no copyleft in the dependency chain. The full security posture - scope minimization, sensitive-path blocking, stateless mode - is documented at workspacemcp.com.

A few things worth internalizing before you connect an LLM to your email:

  • Prompt injection is real. Emails, docs, and events can contain hidden instructions. Only connect trusted data to an LLM, and be deliberate about which write tools you enable.
  • Never commit .env, client_secret.json, or .credentials/ to source control.
  • Local file reads are sandboxed to the managed attachment directory. Broaden with ALLOWED_FILE_DIRS only if you trust the client and its data sources; .env*, ~/.ssh/, ~/.aws/, and similar paths are always blocked.
  • Production deployments should use HTTPS and OAuth 2.1.

Development

uv sync --group dev    # install deps
uv run ruff check .    # lint
uv run pytest          # test

Single-file service modules live in g<service>/, tools are registered with @server.tool decorators, and tiers are defined in core/tool_tiers.yaml. PRs welcome.
