Connect Mailsuite to Claude, ChatGPT and other AI apps (MCP)

Connect Mailsuite to Claude, ChatGPT or any app that supports MCP, and ask about your email the way you would ask a colleague: who opened your proposal, who is waiting for your reply, or what your history with a contact looks like. Your AI app can also send tracked emails and follow-ups from your own address, always after you confirm. Everything you track with Mailtrack is available in your AI app too.

What you need

• A Mailsuite account on the paid plan.
• A Google account with Gmail connected to Mailsuite. Accounts that sign in with Microsoft can’t use the connector.
• If you belong to a Mailsuite team: your team owner must allow AI apps for the team (see Teams below).

The server address is always the same: https://mcp.mailsuite.com

Connect from Claude

You connect once on the web and Mailsuite is then available in Claude on desktop and mobile too, with no extra sign-in.

1. In Claude, open Settings → Connectors.
2. Search for Mailsuite in the directory and click Connect.
3. Claude opens Mailsuite. Sign in if asked, review the permissions and click Allow.
4. Claude now appears under Your connections in Mailsuite, in Settings & account → AI.

Try it: “Who opened my emails this week?”

Connect from ChatGPT

1. In ChatGPT, open Settings → Connectors.
2. Search for Mailsuite in the directory and click Connect.
3. ChatGPT opens Mailsuite. Sign in if asked, review the permissions and click Allow.

If you use ChatGPT in a workspace, your workspace admin may need to allow Mailsuite first.

Try it: “Which contacts are still waiting for my reply?”

Connect from other apps

Any app that supports remote MCP servers can connect with the same address. The first time you use Mailsuite, the app opens Mailsuite in your browser so you can sign in and click Allow.

Claude Code. Run this in your terminal, then type /mcp inside Claude Code to sign in:

claude mcp add --transport http mailsuite https://mcp.mailsuite.com

Cursor. Add this to ~/.cursor/mcp.json, or to .cursor/mcp.json inside your project:

{
  "mcpServers": {
    "mailsuite": {
      "url": "https://mcp.mailsuite.com"
    }
  }
}

VS Code. Add this to .vscode/mcp.json inside your project:

{
  "servers": {
    "mailsuite": {
      "type": "http",
      "url": "https://mcp.mailsuite.com"
    }
  }
}

Gemini and Microsoft Copilot. Add a remote MCP server or custom connector in the app’s settings with the address above, and authorize the access.

Any other app. Look for a field called server, URL or connector. If your app asks for a token instead, create one in Settings & account → AI, under API access.

What your AI app can access

When you click Allow, you grant these permissions. Two more are only requested when you ask for something that needs them.

Nothing is sent without you. Your AI app shows you the recipients and the text and asks for your confirmation before sending. Emails to people you have never written to also wait for your approval in Settings & account → AI, and expire after 72 hours if you don’t approve them.

Mailsuite shares this data only with the AI app you connect; see our Privacy Policy and how we keep your data secure.

Teams

AI apps are off for team members until the team owner turns them on. In Settings & account → Team → AI apps, the owner switches on Allow AI apps for the team. When it’s on, everyone in the team can connect the AI app they choose; when it’s off, nobody in the team can connect an AI app or use an API token.

Disconnect an app

In Settings & account → AI, find the app under Your connections and click Disconnect. It loses access immediately. If you connect the same app again later, the new connection replaces the old one.
