A quick plug for AI-Enhanced Docs

This README was written with AI assistance, and here's why that matters

As a solo dev building open source tools, comprehensive documentation often wouldn't happen without AI help. Using agentic dev tools like Roo & Claude Code that understand the entire codebase, AI doesn't just regurgitate generic content - it extracts real implementation details and creates accurate, specific documentation.
In this case, Sonnet 4 took a pass & a human (me) verified them 8/16/25.

Overview

Connect to Claude Desktop

The server supports two transport modes:

Stdio Mode (Default - Recommended for Claude Desktop)

In general, you should use the one-click DXT installer package for Claude Desktop. If you are unable to for some reason, you can configure it manually via claude_desktop_config.json

Manual Claude Configuration (Alternative)

Open Claude Desktop Settings → Developer → Edit Config
- macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
- Windows: %APPDATA%\Claude\claude_desktop_config.json
Add the server configuration:

{
  "mcpServers": {
    "google_workspace": {
      "command": "uvx",
      "args": ["workspace-mcp"],
      "env": {
        "GOOGLE_OAUTH_CLIENT_ID": "your-client-id",
        "GOOGLE_OAUTH_CLIENT_SECRET": "your-secret",
        "OAUTHLIB_INSECURE_TRANSPORT": "1"
      }
    }
  }
}

2. Advanced / Cross-Platform Installation

If you’re developing, deploying to servers, or using another MCP-capable client, keep reading.

Instant CLI (uvx)

# Requires Python 3.10+ and uvx
# First, set credentials (see Credential Configuration above)
uvx workspace-mcp --tool-tier core  # or --tools gmail drive calendar

Note: Configure OAuth credentials before running. Supports environment variables, .env file, or client_secret.json.

OAuth 2.1 Support (Multi-User Bearer Token Authentication)

The server includes OAuth 2.1 support for bearer token authentication, enabling multi-user session management. OAuth 2.1 automatically reuses your existing GOOGLE_OAUTH_CLIENT_ID and GOOGLE_OAUTH_CLIENT_SECRET credentials - no additional configuration needed!

When to use OAuth 2.1:

Multiple users accessing the same MCP server instance
Need for bearer token authentication instead of passing user emails
Building web applications or APIs on top of the MCP server
Production environments requiring secure session management
Browser-based clients requiring CORS support

Enabling OAuth 2.1: To enable OAuth 2.1, set the MCP_ENABLE_OAUTH21 environment variable to true.

# OAuth 2.1 requires HTTP transport mode
export MCP_ENABLE_OAUTH21=true
uv run main.py --transport streamable-http

If MCP_ENABLE_OAUTH21 is not set to true, the server will use legacy authentication, which is suitable for clients that do not support OAuth 2.1.

This implementation solves two critical challenges when using Google OAuth in browser environments:

Dynamic Client Registration: Google doesn't support OAuth 2.1 dynamic client registration. Our server provides a clever proxy that accepts any client registration request and returns the pre-configured Google OAuth credentials, allowing standards-compliant clients to work seamlessly.
CORS Issues: Google's OAuth endpoints don't include CORS headers, blocking browser-based clients. We implement intelligent proxy endpoints that:

Proxy authorization server discovery requests through /auth/discovery/authorization-server/{server}
Proxy token exchange requests through /oauth2/token
Add proper CORS headers to all responses
Maintain security by only proxying to known Google OAuth endpoints

This architecture enables any OAuth 2.1 compliant client to authenticate users through Google, even from browser environments, without requiring changes to the client implementation.

MCP Inspector: No additional configuration needed with desktop OAuth client.

Claude Code Inspector: No additional configuration needed with desktop OAuth client.

    "servers": {
        "google-workspace": {
            "url": "http://localhost:8000/mcp/",
            "type": "http"
        }
    }
}

Reverse Proxy Setup

If you're running the MCP server behind a reverse proxy (nginx, Apache, Cloudflare, etc.), you'll need to configure GOOGLE_OAUTH_REDIRECT_URI to match your external URL:

Problem: When behind a reverse proxy, the server constructs redirect URIs using internal ports (e.g., http://localhost:8000/oauth2callback) but Google expects the external URL (e.g., https://your-domain.com/oauth2callback).

Solution: Set GOOGLE_OAUTH_REDIRECT_URI to your external URL:

# External URL without port (nginx/Apache handling HTTPS)
export GOOGLE_OAUTH_REDIRECT_URI="https://your-domain.com/oauth2callback"

# Or with custom port if needed
export GOOGLE_OAUTH_REDIRECT_URI="https://your-domain.com:8443/oauth2callback"

Important:

The redirect URI must exactly match what's configured in your Google Cloud Console
The server will use this value for all OAuth flows instead of constructing it from WORKSPACE_MCP_BASE_URI and WORKSPACE_MCP_PORT
Your reverse proxy must forward /oauth2callback requests to the MCP server

# Configure credentials first (see Credential Configuration section)

# Start with specific tools only
uvx workspace-mcp --tools gmail drive calendar tasks

# Start with tool tiers (recommended for most users)
uvx workspace-mcp --tool-tier core      # Essential tools
uvx workspace-mcp --tool-tier extended  # Core + additional features
uvx workspace-mcp --tool-tier complete  # All tools

# Start in HTTP mode for debugging
uvx workspace-mcp --transport streamable-http

Requires Python 3.10+ and uvx. The package is available on PyPI.

Development Installation

For development or customization:

git clone https://github.com/taylorwilsdon/google_workspace_mcp.git
cd google_workspace_mcp
uv run main.py

Development Installation (For Contributors):

{
  "mcpServers": {
    "google_workspace": {
      "command": "uv",
      "args": [
        "run",
        "--directory",
        "/path/to/repo/google_workspace_mcp",
        "main.py"
      ],
      "env": {
        "GOOGLE_OAUTH_CLIENT_ID": "your-client-id",
        "GOOGLE_OAUTH_CLIENT_SECRET": "your-secret",
        "OAUTHLIB_INSECURE_TRANSPORT": "1"
      }
    }
  }
}

HTTP Mode (For debugging or web interfaces)

If you need to use HTTP mode with Claude Desktop:

{
  "mcpServers": {
    "google_workspace": {
      "command": "npx",
      "args": ["mcp-remote", "http://localhost:8000/mcp"]
    }
  }
}

Note: Make sure to start the server with --transport streamable-http when using HTTP mode.

First-Time Authentication

The server uses Google Desktop OAuth for simplified authentication:

No redirect URIs needed: Desktop OAuth clients handle authentication without complex callback URLs
Automatic flow: The server manages the entire OAuth process transparently
Transport-agnostic: Works seamlessly in both stdio and HTTP modes

When calling a tool:

Server returns authorization URL
Open URL in browser and authorize
Google provides an authorization code
Paste the code when prompted (or it's handled automatically)
Server completes authentication and retries your request

Architecture Highlights

Service Caching: 30-minute TTL reduces authentication overhead
Scope Management: Centralized in SCOPE_GROUPS for easy maintenance
Error Handling: Native exceptions instead of manual error construction
Multi-Service Support: @require_multiple_services() for complex tools

Credential Store System

The server includes an abstract credential store API and a default backend for managing Google OAuth credentials with support for multiple storage backends:

Features:

Abstract Interface: CredentialStore base class defines standard operations (get, store, delete, list users)
Local File Storage: LocalDirectoryCredentialStore implementation stores credentials as JSON files
Configurable Storage: Environment variable GOOGLE_MCP_CREDENTIALS_DIR sets storage location
Multi-User Support: Store and manage credentials for multiple Google accounts
Automatic Directory Creation: Storage directory is created automatically if it doesn't exist

Configuration:

# Optional: Set custom credentials directory
export GOOGLE_MCP_CREDENTIALS_DIR="/path/to/credentials"

# Default locations (if GOOGLE_MCP_CREDENTIALS_DIR not set):
# - ~/.google_workspace_mcp/credentials (if home directory accessible)
# - ./.credentials (fallback)

Usage Example:

from auth.credential_store import get_credential_store

# Get the global credential store instance
store = get_credential_store()

# Store credentials for a user
store.store_credential("user@example.com", credentials)

# Retrieve credentials
creds = store.get_credential("user@example.com")

# List all users with stored credentials
users = store.list_users()

The credential store automatically handles credential serialization, expiry parsing, and provides error handling for storage operations.

⊠ Security

Credentials: Never commit .env, client_secret.json or the .credentials/ directory to source control!
OAuth Callback: Uses http://localhost:8000/oauth2callback for development (requires OAUTHLIB_INSECURE_TRANSPORT=1)
Transport-Aware Callbacks: Stdio mode starts a minimal HTTP server only for OAuth, ensuring callbacks work in all modes
Production: Use HTTPS & OAuth 2.1 and configure accordingly
Network Exposure: Consider authentication when using mcpo over networks
Scope Minimization: Tools request only necessary permissions
