Overview

This is a comprehensive MCP server setup that provides Claude Code with access to multiple Google Workspace accounts (Gmail, Drive, Calendar, Sheets, Docs) and Slack. The project includes both AI-guided setup via CLAUDE.md and manual setup instructions. It addresses complex challenges like handling multiple Google accounts with separate OAuth clients and token management through a wrapper script.

Try asking AI

After installing, here are 5 things you can ask your AI assistant:

you:Accessing emails and documents across multiple Google accounts
you:Managing calendar events and tasks from Slack and Google Workspace
you:Searching and retrieving content from Google Drive and Slack conversations
you:Why can't I use settings.local.json for MCP configuration?
you:How do I handle multiple Google accounts?

When to choose this

Choose this if you need to access multiple Google Workspace accounts and Slack through Claude Code, especially when official integrations aren't available yet.

When NOT to choose this

Don't choose this if you're already using Claude Desktop/Cowork which has built-in Google Workspace integrations, or if you need write access beyond what Google's official CLI provides.

Manual Setup

Refer to [docs/manual-setup.md](docs/manual-setup.md) for detailed step-by-step instructions.

Configuration

Create .mcp.json at project root with:

{
  "mcpServers": {
    "gws-personal": {
      "command": "bash",
      "args": ["./gws-token-wrapper.sh", "personal.json"]
    },

      "args": ["slack-mcp-server"]

FAQ

Why can't I use settings.local.json for MCP configuration?
Claude Code silently ignores MCP config in settings.local.json. You must use .mcp.json at project root or ~/.claude.json for global configuration.
How do I handle multiple Google accounts?
Create separate OAuth Desktop App clients for each Google account in the same GCP project. Use a token wrapper script to mint fresh access tokens for each account.
