Summary
Connects Claude directly to your churn data through Stripe, Postgres, or MySQL using read-only credentials that stay in your local MCP config. Exposes four tools: analyze_churn for pasted feedback, analyze_stripe_churn to pull canceled subscriptions with MRR and cancelation context, analyze_sql_churn that generates safe SELECT queries from your schema description, and get_example_analysis for output shape preview. Returns structured insights with severity scores, confidence ratings, and specific recommendations ranked by impact. Built for agents to reason about retention without leaving your editor. The SQL tool hard-caps at 500 rows, applies 15-second timeouts, and validates table names against an allowlist before execution. If you run a SaaS and want churn analysis in your coding workflow without CSV exports or dashboard context switching, this slots in fast.
