Google Workspace MCP Server

Name: google_workspace_mcp
Author: taylorwilsdon

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!

Support for all free Google accounts & Google Workspace plans (Starter, Standard, Plus, Enterprise, Non Profit) with expanded app options like Chat & Spaces.

Interested in a private, managed cloud instance? That can be arranged.

See it in action:

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:

Where to go	What you'll find
Quick Start	Google Cloud setup, credentials, and client connection with screenshots
Full Documentation	Every tool, parameter, and auth mode
Advanced Deployment	Reverse proxy & nginx config, origin validation, credential store backends (GCS/CMEK), and the complete environment variable reference
Client Setup Guides	Claude Desktop/web Connectors, ChatGPT Developer Mode, and more
FAQ & Troubleshooting	OAuth errors, redirect URIs, Google Chat setup, client quirks

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

💬 Google Chat needs a one-time Chat app configuration and a Workspace account - see the Chat setup FAQ.

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:

OAuth 2.1 multi-user auth - bearer tokens, required for remote or shared HTTP endpoints
Stateless container mode - zero disk writes for locked-down deployments
OAuth proxy storage backends - memory, disk, or Valkey/Redis for distributed setups
External OAuth provider mode - bring your own auth server, validate bearer tokens only
Service accounts with domain-wide delegation - per-request user impersonation with an optional domain allowlist
OpenTelemetry tracing - optional, off unless you configure an OTLP endpoint
Docker - docker build -t workspace-mcp . && docker run -p 8000:8000 workspace-mcp

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.
