Connect ChurnLens and your agent gets 6 tools, among them analyze_revenue_concentration, calculate_churn_rate, calculate_ltv. It answers at https://churnlens.site/api/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 22 October 2026, succeeded.
Buyer-side SaaS due-diligence maths: NRR, GRR, revenue concentration, zombie MRR, LTV:CAC.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
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? Inputs: customer_mrrs, top_n, whale_threshold_pct |
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 expans Inputs: starting_mrr, expansion_mrr, contraction_mrr, churned_mrr |
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. Inputs: arpa, monthly_churn_rate_pct, gross_margin_pct, cac |
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. Inputs: accounts, threshold_days |
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. Inputs: metric |
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. Inputs: monthly_churn_rate_pct, nrr_pct, top_customer_share_pct, ltv_to_cac_ratio, annual_plan_share_pct |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://churnlens.site/api/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
