Official PostHog MCP — query session replays, funnels, heatmaps, and feature flags from Claude for design-led decisions.
npx -y @posthog/wrapper-mcpPostHog's first-party MCP exposes product analytics, session replays, and experiment data to Claude. Designers can ask "where do users drop off in onboarding?" or "pull replays from users who hit my new component" and get answers backed by real telemetry — a designer's bridge to the data team.
Use when asked to "define our core action", "North Star metric", "accruing benefits", "improve retention mechanics", "hierarchy of engagement", or "Sarah Tavel framework".
Defines a primary success metric plus 2-3 secondary metrics for a feature or initiative, with exact definitions, measurement method and targets.
Designs an A/B test or experiment with variants, success metrics, sample size, and duration for an existing hypothesis.
