Workmagic MCP: incrementality testing and attribution in your AI app

Workmagic runs incrementality tests and uses them as ground truth to calibrate attribution and marketing mix modeling (MMM). Its MCP server connects your AI app to your Workmagic account, and the exact tools appear once you sign in. ContextGate connects it to Claude, ChatGPT and Cursor, and Activity shows each question your team asks about marketing performance.
