email-mcp

Built by Shreyas · Shipped by Globalion

Give any AI agent — or your own Telegram bot — read and send access to your Gmail. One Google sign-in, one MCP URL, one bot token. No IMAP passwords, no app-passwords, no scraping.

• MCP over streamable-HTTP for Claude Desktop, Cursor, Windsurf, anything.

• Telegram bot for chatting to your inbox in natural English.

• Gmail API — free, generous per-user quota, official OAuth.

Hosted for free at email.regiq.in or self-host with the Docker Compose below.

Use it (hosted)

As an MCP tool

1. Visit https://email.regiq.in and sign in with Google.

2. Copy your API key from the dashboard.

3. Add to Claude Desktop's claude_desktop_config.json:

   {
     "mcpServers": {
       "email": {
         "url": "https://email.regiq.in/api/mcp",
         "headers": {
           "Authorization": "Bearer YOUR_KEY_HERE"
         }
       }
     }
   }

4. Restart Claude Desktop. Ask it: "summarise my last 5 emails and mark them read" or "reply to Alex saying I can do Tuesday".

As a Telegram bot

1. Sign in at https://email.regiq.in.

2. In Telegram, DM @BotFather → /newbot.

3. Paste the bot token BotFather gives you into the Telegram bot panel on the dashboard.

4. Open your bot in Telegram, send /start, then chat with it.

Tools

Self-host

You'll need:

• Docker + Compose

• A Google OAuth client — Cloud Console

  • Scopes: openid, email, profile, gmail.readonly, gmail.send

  • Redirect URI: <PUBLIC_BASE_URL>/api/auth/callback/google

• An Anthropic API key — console.anthropic.com

• A public HTTPS domain if you want Telegram webhooks to work (Telegram refuses plain HTTP). Cloudflare Tunnel or ngrok http 3011 locally.

Then:

git clone https://github.com/globalion/email-mcp
cd email-mcp
cp .env.example .env
# fill in NEXTAUTH_SECRET, GOOGLE_CLIENT_*, ANTHROPIC_API_KEY, PUBLIC_BASE_URL
docker compose up -d
# open http://localhost:3011

How it works

                       │ (Haiku) │  summarises for the user.
                       └────┬────┘
                            ▼
                       ┌─────────┐
                       │  Gmail  │  Per-user OAuth refresh token
                       │   API   │  → short-lived access tokens
                       └─────────┘

Every user's Google refresh token stays server-side. The Telegram bot token is user-scoped — one leaked webhook URL can't be pointed at someone else's account because the URL segment is a per-user random secret.
