How to choose
If the deliverable is a branded report for each client, compare Whatagraph with AgencyAnalytics. If you mainly need marketing data inside BI tools or an AI chat, Windsor.ai and Supermetrics start lower. If your agency already works through Claude or ChatGPT and wants a record of what was decided, the OneLap waitlist is the place to start.
Supermetrics’ MCP page says access comes with any subscription and also names plans with Data API access, so confirm your plan with them.
