MCP connector · Claude & AI assistants

Talk to your email data in plain language

The mailcheck MCP connector links your email open tracking to Claude. You ask the question, the AI queries your data and answers. No dashboard to dig through, no formula to write.

The connector works with the mailcheck extension. It queries the opens collected by the Chrome extension in Gmail and Zoho Mail. Install the extension first to track your emails, then query your data with Claude.
