## Tools
- calculate_churn_rate - Calculate net revenue retention (NRR), gross revenue retention (GRR), revenue churn and implied customer lifetime from one period's MRR movements. Also reports the NRR-minus-GRR spread, which reveals how much churn is being masked by expansion revenue. Endpoint: https://churnlens.site/api/mcp
- analyze_revenue_concentration - Assess customer concentration risk across a book of revenue using the Herfindahl-Hirschman Index (HHI), top-N share and whale detection. Answers the question every acquirer asks first: how much revenue walks out with one logo? Endpoint: https://churnlens.site/api/mcp
- detect_zombie_mrr - Identify dormant-but-paying accounts — revenue that still counts in MRR but whose customers have stopped showing up. Zombie revenue is one renewal notice from cancelling and is invisible to standard revenue dashboards. Endpoint: https://churnlens.site/api/mcp
- score_saas_health - Score a SaaS business 0-100 across five dimensions — retention, growth, concentration, efficiency and durability — and return the composite. Every mapping is published, so the score can be reconstructed by hand. Endpoint: https://churnlens.site/api/mcp
- calculate_ltv - Calculate gross-margin-adjusted customer lifetime value, the LTV:CAC ratio and CAC payback in months. Omitting gross margin yields lifetime revenue rather than lifetime value — usually a third of the number. Endpoint: https://churnlens.site/api/mcp
- get_scoring_bands - Return the scoring thresholds ChurnLens applies to NRR, revenue concentration and the composite health score. These are bands, not measured benchmark data — the sourced benchmark figures are cited at https://churnlens.site/benchmarks. Endpoint: https://churnlens.site/api/mcp
