    PostHog MCP for your AI agent

    Cogny's PostHog integration exposes 15 tools (15 read) to an AI agent over MCP. The same tools are available on every plan, from your own AI client or inside the Cogny app.

    • 15readonly reads data.
    • 0writecreates or changes something.
    • 0destructivedeletes, removes or replaces something.

    Over MCP your own AI client asks before it runs a write. To take a tool away from your agent, block it in Settings → Integrations. Plans, approvals and limits

    set it up.

    Add Cogny to your AI client once, then connect PostHog in Cogny. Every PostHog tool below appears in the client.
