Gmail MCP Server

An MCP (Model Context Protocol) server that provides Gmail integration for AI assistants. Search emails, read messages, and download attachments directly from your Gmail account.

Features

• Search emails using Gmail's powerful search syntax (from:, subject:, has:attachment, etc.)
• Read full email content including body and attachment metadata
• Download attachments to your local filesystem

Quick Start

1. Set up Google Cloud credentials

1. Go to Google Cloud Console
2. Create a new project (or select existing)
3. Enable the Gmail API
4. Go to APIs & Services > Credentials
5. Click Create Credentials > OAuth client ID
6. Select Desktop app as application type
7. Download the JSON file and save it:

mkdir -p ~/.gmail-mcp
mv ~/Downloads/client_secret_*.json ~/.gmail-mcp/gcp-oauth.keys.json

2. First-time authorization

Run once to complete OAuth (opens browser):

uvx mcp-gmail-reader

---

Backup & Recovery

After a fresh OS install or losing your machine, here's what to restore:

File	Where	Backup?	Recovery
~/.gmail-mcp/gcp-oauth.keys.json	Local only	YES — password manager	Cannot regenerate without recreating GCP project
~/.gmail-mcp/token.json	Local only	No	Regenerated by running uvx mcp-gmail-reader once (browser flow)
~/Documents/gmail-mcp/ (this repo)	Git	No need — git clone	git clone https://github.com/Maheidem/gmail-mcp.git
MCP registration	~/.claude/settings.json	No	Re-add the JSON snippet from "Claude Code (CLI)" section above

Recovery checklist (5 minutes after a fresh machine)

# 1. Clone the source
git clone https://github.com/Maheidem/gmail-mcp.git ~/Documents/gmail-mcp

# 2. Restore credentials from your password manager
mkdir -p ~/.gmail-mcp
# (paste gcp-oauth.keys.json into ~/.gmail-mcp/)

# 3. Install + first-run authorization (opens browser)
uvx mcp-gmail-reader

# 4. Re-register in Claude Code (see "Claude Code (CLI)" section below)

The OAuth credentials JSON is the only thing that cannot be recovered without doing the full Google Cloud Console setup again. Back it up.
