It's easy to get lost in the noise of expansion, contraction, and churn. This MCP lets you stop doing the manual math. You can just tell your agent to run the numbers on a specific customer cohort and it'll spit out the Net Revenue Retention and Gross Revenue Retention immediately. It also knows what the "good" numbers look like for different sizes of customers, so you don't have to guess if your growth is actually impressive or just average. It's about getting a clear picture of your subscription stability without the headache of building custom formulas every time. You can see exactly how much revenue you're losing to churn versus how much you're gaining from expansion. It helps you see where the revenue is leaking and where it's actually growing. Since it's part of the Vinkius catalog, you can plug it into your existing AI workflow and get these answers in seconds. It's the truth layer for your finance stack. Instead of hunting through tabs to find the starting MRR for a specific group, you just feed the raw figures to your agent and get a health rating. It turns messy data into a clear "World Class" or "Healthy" status so you can make moves based on facts. ## Tools ### calculate_retention_metrics Computes NRR and GRR for a specific cohort based on MRR changes. ### evaluate_cohort_health Assigns a health status like World Class or Healthy based on your NRR. ### get_segment_benchmarks Returns the target NRR and GRR for SMB or Enterprise segments. ## Prompt Examples **Prompt:** ``` Calculate retention for a cohort with 100k starting MRR, 10k expansion, 5k contraction, and 2k churn in the Enterprise segment. ``` **Response:** ``` The calculated Net Revenue Retention (NRR) is 103.0% and the Gross Revenue Retention (GRR) is 93.0%. ``` **Prompt:** ``` What are the performance targets for the SMB segment? ``` **Response:** ``` For the SMB segment, the target NRR is 100.0% and the target GRR is 95.0%, categorized as a High-Growth tier. ``` **Prompt:** ``` Is an NRR of 125% in the Enterprise segment considered good? ``` **Response:** ``` Yes, an NRR of 125.0% for the Enterprise segment is classified as World Class status. ``` ## Capabilities ### Calculate NRR and GRR Get retention percentages for a specific customer cohort based on your revenue changes. ### Check cohort health See if your current retention meets industry standards like World Class or Healthy. ### Pull segment benchmarks Find out what Enterprise or SMB targets actually look like for your industry. ### Analyze revenue leaks Identify how much revenue you're losing to churn versus what you're gaining from expansion. ### Compare growth tiers Determine if your performance sits in a high-growth category or a standard tier. ## Use Cases ### Monthly reporting A finance lead asks the agent to calculate retention for the Q3 Enterprise cohort using calculate_retention_metrics. ### Growth check A manager wants to know if a 120% NRR is good for SMBs, so they use evaluate_cohort_health. ### Target setting An analyst uses get_segment_benchmarks to set new KPIs for the sales team based on high-growth tiers. ### Churn analysis A product manager wants to see how much contraction is hurting the Healthy status of their current users. ## Benefits - Stop manual math: Use calculate_retention_metrics to get NRR and GRR instantly without opening a spreadsheet. - Benchmark your growth: Use get_segment_benchmarks to see how your numbers stack up against high-growth targets. - Identify health gaps: Use evaluate_cohort_health to see if your retention is actually World Class or just okay. - Faster reporting: Get cohort analysis results in seconds so you can spend more time on strategy and less on data entry. - Accurate segmentation: Get specific targets for SMB versus Enterprise segments to make better pricing decisions. ## How It Works The bottom line is you get instant, accurate retention data instead of manual spreadsheet errors. 1.
