Requirements

• Python 3.12+
• UV package manager
• Node.js 18+ and npm (required for MCP Apps UI in src/mcp_google_workspace/apps/ui)
• Google Cloud OAuth desktop credentials (credentials.json)
• Google APIs enabled in your Google Cloud project: Gmail, Calendar, Drive, Sheets, Docs, Tasks, People, Forms, and Slides
• Optional APIs when enabling feature-flagged integrations: Google Keep, Google Chat, and Google Meet
• Gemini Developer API key when enabling Gemini media tools

Installation

uv sync --all-extras --dev

If you are working on MCP Apps UI, install frontend dependencies and build the bundle:

cd src/mcp_google_workspace/apps/ui
npm ci
npm run build

OAuth setup

Place credentials.json in one of:

• project root: ./credentials.json
• package credentials folder: ./src/credentials/credentials.json

On first run, the server launches a browser for OAuth consent and writes token.json.

Optional service feature flags

Sheets, Docs, Tasks, People, Forms, and Slides are mounted by default and their scopes are always requested. If you are upgrading from an older checkout, delete token.json once so OAuth can re-consent the expanded scope set.

Google Keep OAuth scope can return invalid_scope in standard user OAuth flows. Keep integration is therefore disabled by default.

Enable Keep when your Google Workspace setup supports it:

$env:ENABLE_KEEP="true"

Google Chat OAuth scopes also commonly require Google Workspace accounts. Chat integration is therefore disabled by default.

Enable Chat when your Google Workspace setup supports it:

$env:ENABLE_CHAT="true"

Google Meet integration is also disabled by default. Enable it only after enabling the Meet API for the same OAuth client:

$env:ENABLE_MEET="true"

Gemini media integration is also disabled by default. Enable it with a Gemini Developer API key:

$env:ENABLE_GEMINI="true"
$env:GEMINI_API_KEY="your-api-key"

Capability-specific Gemini model defaults:

$env:GEMINI_IMAGE_GENERATE_MODEL="gemini-3.1-flash-image-preview"
$env:GEMINI_IMAGE_EDIT_MODEL="gemini-3.1-flash-image-preview"
$env:GEMINI_VIDEO_UNDERSTANDING_MODEL="gemini-3-flash-preview"
$env:GEMINI_AUDIO_UNDERSTANDING_MODEL="gemini-3-flash-preview"
$env:GEMINI_REASONING_MODEL="gemini-3.1-pro-preview"

Whenever you enable one of these optional integrations or otherwise change the scope set, delete token.json and re-authenticate to refresh granted scopes.

Apps dashboard rollout flag

The MCP app-layer dashboard namespace is opt-in for controlled rollout.

Enable apps namespace:

$env:ENABLE_APPS_DASHBOARD="true"

Run (STDIO)

uv run python -m mcp_google_workspace
