Overview

Description from the maker (original English)

Multi-account Google Workspace MCP server: 944 tools, 29 services, discover-first, BYO OAuth.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Other
  • You need to fill in: GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET, GOOGLE_ACCOUNTS, MASTER_KEY

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET, GOOGLE_ACCOUNTS, MASTER_KEY

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Download the maker’s .mcpb file

The link goes to the maker’s own file; we do not host or repackage it. Open the file and Claude Desktop installs it.

Run this in your terminal

claude mcp add google-multi --env GOOGLE_CLIENT_ID=your-value --env GOOGLE_CLIENT_SECRET=your-value --env GOOGLE_ACCOUNTS=your-value --env MASTER_KEY=your-value -- npx -y mcp-google-multi

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "google-multi": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-google-multi"
      ],
      "env": {
        "GOOGLE_CLIENT_ID": "your-value",
        "GOOGLE_CLIENT_SECRET": "your-value",
        "GOOGLE_ACCOUNTS": "your-value",
        "MASTER_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "google-multi": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "mcp-google-multi"
      ],
      "env": {
        "GOOGLE_CLIENT_ID": "your-value",
        "GOOGLE_CLIENT_SECRET": "your-value",
        "GOOGLE_ACCOUNTS": "your-value",
        "MASTER_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • GOOGLE_CLIENT_ID required env
    OAuth 2.0 Desktop client ID from your own Google Cloud project (docs/google-cloud-setup.md).
  • GOOGLE_CLIENT_SECRET secret required env
    OAuth 2.0 Desktop client secret paired with GOOGLE_CLIENT_ID.
  • GOOGLE_ACCOUNTS required env
    Comma-separated alias:email pairs, e.g. work:you@company.com,personal:you@gmail.com.
  • MASTER_KEY secret env
    Base64 32-byte key encrypting the local token store; auto-generated and stored for you when unset.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Google Workspace (multi-account) safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET, GOOGLE_ACCOUNTS, MASTER_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (6.2.0) reached the registry 2 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js, Docker, MCPB on your computer.

What can I use instead?

mcp-google-multi

The most complete local Google Workspace MCP server: Gmail, Drive, Calendar, Sheets, Docs, Slides, Forms, Contacts, Tasks, Chat, Meet, Analytics (GA4), Search Console, Classroom, Vault, Admin and more — every OAuth-reachable API method as a tool, across multiple Google accounts at once, from Claude Code or any MCP client.

  • 🧰 Exhaustive — 944 tools across 29 services, now including Google Analytics (GA4), + an escape hatch for anything else → 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
  • 🌐 Local or remote — runs locally over stdio, or self-hosted over HTTP with its own built-in OAuth 2.1 server (Claude Code's /mcp login and the claude.ai connector, zero custom UI). Pull-and-up Docker Compose with optional automatic HTTPS → remote setup
  • ✉️ Built for real work — send and read email in Markdown with attachments and one-call replies, an interactive setup wizard with a doctor self-check, and per-account scope profiles → features tour

Quick setup

New to all this? It's written for someone who just installed Claude Code and has never made an API key. Copy-paste each step; it says what you'll see. (Already technical? The Configuration reference is the terse version.)

  1. Install it. Get Node.js (the green "LTS" button, version 22 or newer), then run:
   npm install -g mcp-google-multi

Claude Desktop user? You can skip npm entirely: download the mcp-google-multi.mcpb bundle from the latest release, double-click it (or drag it into Claude Desktop → Settings → Extensions), and fill in the values from step 2 when prompted.

  1. Make your Google key (the one manual part, a few minutes, because Google has no way to script it). Follow the step-by-step Google Cloud setup, or just ask Claude Code: *"walk me through creating a Google OAuth Desktop client for mcp-google-multi."* You finish with two values, a Client ID and a Client Secret. It's free and private to you.
  1. Put them in a file. In the folder you'll run from, make a file named .env and paste this, filling in your values:
   GOOGLE_CLIENT_ID=paste-your-client-id

GOOGLE_CLIENT_SECRET=paste-your-client-secret

any short nickname, then your Gmail address:

GOOGLE_ACCOUNTS=me:you@gmail.com

No encryption key to make: the server generates and stores one for you.

  1. Sign in. A browser opens; pick your account and click Allow:
   mcp-google-multi auth --account me
  1. Add it to Claude Code, then restart Claude Code:
   claude mcp add mcp-google-multi -s user -- npx -y mcp-google-multi

Stuck at any point? Run `mcp-google-multi doctor`. It inspects every part and prints the exact fix for anything wrong (a missing sign-in, a Google API you still need to switch on, and so on). Once it reads all-green, just talk to Claude: *"summarize my unread email."*

*Got more than one Google account?* Add them together, like GOOGLE_ACCOUNTS=me:you@gmail.com,work:you@company.com, and run step 4 once per nickname.

*On a server or from claude.ai?* Advanced path: Remote / HTTP setup. *Coming from v5?* v6 migration guide.

Agent skill

The repo and the npm package both ship an Agent Skill at skills/google-workspace/: a hand-written SKILL.md covering account selection, the discover step, incremental Gmail sweeps, keeping results small, write profiles, and the escape hatch, plus a reference/ folder with a generated argument table per service. Loading it gets an agent calling this server's tools correctly without guessing argument names.

To install it for Claude Code, copy or symlink the skills/google-workspace folder into ~/.claude/skills/ (every project) or a project's own .claude/skills/ (that project only):

# from a cloned copy of this repo

ln -s "$(pwd)/skills/google-workspace" ~/.claude/skills/google-workspace

from the installed npm package

ln -s "$(npm root -g)/mcp-google-multi/skills/google-workspace" ~/.claude/skills/google-workspace
