mcp-google-multi

# mcp-google-multi The most complete **local Google Workspace MCP server**: Gmail, Drive, Calendar, Sheets, Docs, Slides, Forms, Contacts, Tasks, Chat, Meet, Classroom, Vault, Admin and more — **every OAuth-reachable Workspace API method** as a tool, across **multiple Google accounts** at once, from Claude Code or any MCP client. [](https://www.npmjs.com/package/mcp-google-multi) - 🧰 **Exhaustive** — 872 tools across 28 services + an escape hatch for anything else → [COVERAGE.md](./COVERAGE.md) - 🔑 **Multi-account** — drive any number of Google accounts by alias, or fan one call out across all of them - 🔒 **Private by design** — your own OAuth app, tokens encrypted at rest (AES-256-GCM), writes deny-by-default, no telemetry, no metering — it talks only to Google ## Quick setup You don't need to know anything about MCP or OAuth — five steps, all copy-paste: 1. **Install [Node.js](https://nodejs.org) 20 or newer**, then install the server: ```bash npm install -g mcp-google-multi ``` 2. **Create your (free) Google app** so the server can sign in as you — one-time, ~2 minutes: follow [Google Cloud setup](./docs/google-cloud-setup.md). You come back with a **Client ID** and **Client Secret**. 3. **Create a file named `.env`** in the folder you'll run from, and fill in your values: ```bash GOOGLE_CLIENT_ID=paste-your-client-id GOOGLE_CLIENT_SECRET=paste-your-client-secret # name each Google account with a short alias: GOOGLE_ACCOUNTS=work:you@company.com,personal:you@gmail.com # encryption key for stored tokens — generate one with: openssl rand -base64 32 MASTER_KEY=paste-the-generated-key ``` 4. **Sign in each account** (a browser window opens; approve the permissions): ```bash mcp-google-multi auth --account work mcp-google-multi auth --account personal ``` 5. **Connect it to Claude Code** (any MCP client works the same way): ```bash claude mcp add google-multi -s user -- npx -y mcp-google-multi ``` Restart your client and the tools appear. Check everything with `mcp-google-multi config check`. **Go deeper:** [Configuration reference](./docs/configuration.md) · [What's covered](./COVERAGE.md) · [Features tour](./docs/features.md) · [Secrets in a vault](./docs/secrets.md) · [Upgrading from v4](./docs/upgrading-v4.md) · [Security policy](./SECURITY.md) · [Roadmap](https://github.com/bakissation/mcp-google-multi/milestones) ## Maintainer & credits Built and maintained by **Abdelbaki Berkati** — [berkati.xyz](https://berkati.xyz) · [@bakissation](https://github.com/bakissation).
