Est-ce que io.github.kindrat86/churnlens est sûr ?

Au dernier audit MCP Hub, le serveur MCP « io.github.kindrat86/churnlens » est classé « Non encore testé ». Référencé dans l'annuaire. Seul le pentest comportemental fait foi, et il n'a pas encore été exécuté sur ce serveur. Le verdict est réévalué en continu ; consultez la fiche pour l'état à jour.

Méthode : MCP Hub analyse la description de chaque outil (couche 1) et, pour le verdict fort, exécute le serveur dans une micro-VM isolée avec leurres et réseau bloqué (couche 2). On publie des noms et des compteurs, jamais le contenu brut renvoyé par un outil.

Les 6 outils

• analyze_revenue_concentration≈ 186 tokens

  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?

  Paramètres, retour & exemple (3)

  Paramètres

  • top_n · number · optionnel
    How many top customers to aggregate for the top-N share. Default 5.
  • customer_mrrs · array · requis
    Per-customer MRR values. Order does not matter.
  • whale_threshold_pct · number · optionnel
    Revenue share above which a customer counts as a whale. Default 25.

  Exemple d'appel

  {"name": "analyze_revenue_concentration", "arguments": {"customer_mrrs": []}}

• calculate_churn_rate≈ 207 tokens

  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.

  Paramètres, retour & exemple (4)

  Paramètres

  • churned_mrr · number · optionnel
    MRR lost to full cancellations.
  • starting_mrr · number · requis
    MRR at the start of the period, in any single currency unit.
  • expansion_mrr · number · optionnel
    MRR gained from upgrades and expansion within the existing base. Excludes new customers.
  • contraction_mrr · number · optionnel
    MRR lost to downgrades (customer retained).

  Exemple d'appel

  {"name": "calculate_churn_rate", "arguments": {"starting_mrr": 1}}

• calculate_ltv≈ 196 tokens

  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.

  Paramètres, retour & exemple (4)

  Paramètres

  • cac · number · optionnel
    Customer acquisition cost. Optional — supply it to get the ratio and payback.
  • arpa · number · requis
    Average revenue per account, per month.
  • gross_margin_pct · number · optionnel
    Gross margin percentage. Defaults to 100, which gives lifetime revenue.
  • monthly_churn_rate_pct · number · requis
    Monthly churn, as a percentage.

  Exemple d'appel

  {"name": "calculate_ltv", "arguments": {"arpa": 1, "monthly_churn_rate_pct": 1}}

• detect_zombie_mrr≈ 187 tokens

  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.

  Paramètres, retour & exemple (2)

  Paramètres

  • accounts · array · requis
    One entry per paying account.
  • threshold_days · number · optionnel
    Days of inactivity before an account counts as dormant. Default 90.

  Exemple d'appel

  {"name": "detect_zombie_mrr", "arguments": {"accounts": []}}

  Exemple de retour

  {"content": [{"type": "text", "text": "…"}]}

• get_scoring_bands≈ 126 tokens

  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.

  Paramètres, retour & exemple (1)

  Paramètres

  • metric · string · optionnel · nrr | concentration | health
    Which band set to return: 'nrr', 'concentration', 'health', or omit for all.

  Exemple d'appel

  {"name": "get_scoring_bands", "arguments": {"metric": "nrr"}}

  Exemple de retour

  {"content": [{"type": "text", "text": "…"}]}

• score_saas_health≈ 248 tokens

  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.

  Paramètres, retour & exemple (5)

  Paramètres

  • nrr_pct · number · requis
    Net revenue retention, as a percentage.
  • ltv_to_cac_ratio · number · requis
    Lifetime value divided by customer acquisition cost.
  • annual_plan_share_pct · number · requis
    Share of revenue on annual contracts, as a percentage.
  • monthly_churn_rate_pct · number · requis
    Monthly revenue churn, as a percentage (5 means 5%).
  • top_customer_share_pct · number · requis
    Largest single customer's share of revenue, as a percentage.

  Exemple d'appel

  {"name": "score_saas_health", "arguments": {"nrr_pct": 1, "ltv_to_cac_ratio": 1, "annual_plan_share_pct": 1, "monthly_churn_rate_pct": 1, "top_customer_share_pct": 1}}
