Mixpanel Retention Analyzer

Mixpanel Retention Analyzer is a Level-2 MCP agent for product/growth analysts. It pulls retention and cohort reports from a read-only analytics API (Mixpanel or Amplitude) — or analyzes a provided export — and computes retention curves, per-period drop-off, cohort comparisons, and churn entirely deterministically in code. An LLM is used only to narrate insights, recommendations, and a summary over these code-derived numbers; it never produces or alters a metric. Ships with a deterministic template fallback when no LLM key or host sampling is available. Currently gated: without a sandbox analytics key, it runs against a provided export or deterministic mock fixtures with no live network calls. Ideal for teams who want trustworthy, reproducible retention diagnostics instead of LLM-hallucinated metrics.
