  • All your PostHog data

    Events, pageviews and their properties, ready to ask about.

  • Always today's numbers

    Persons with UTM and referrer properties, synced from PostHog automatically, so answers use today's numbers.

  • Connect all your tools

    Questions like "What does an activated user cost?" use PostHog and Mixpanel, GA4 at once.

Then tell me to refresh MCP servers and choose Authenticate next to Lemonado. Once I've signed in, list the PostHog accounts Lemonado can reach.
