Works with Claude, ChatGPT, Cursor, and more

The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.

This connection provides 5 powerful capabilities that interface natively with Claude, ChatGPT, Cursor, and other compatible AI platforms. No middleware. No custom integration required.

The spreadsheet headache of tracking growth sources

Most companies start by pulling raw subscription data into an enormous sheet. They manually calculate the total MRR, then they try to segment it: 'Did that $50k come from New? Or was that an upgrade?' This requires juggling multiple tabs and constantly copy-pasting numbers between sheets just to get a basic picture of your growth engine.

With this MCP, you connect your data once. The system runs the complex logic to separate those components instantly. You don't just get one total number; you get a clear breakdown showing exactly how much was New money and how much came from Expansion—the full story.

See Your True Financial Health with `get_metrics_summary`

Before, getting a 'full picture' meant running five different reports: one for MRR, one for LTV, another for Churn Rate, and so on. You’d have to pull these individual metrics from separate dashboards or specialized tools.

Now you run the MCP flow once. The `get_metrics_summary` tool pulls everything together, giving you a unified view of your business health in seconds. It's one single source for every key financial ratio.

What your AI can actually do with this

Understanding recurring revenue goes way beyond just looking at a single gross number. The real challenge in SaaS finance is figuring out the source of growth: did it come from new clients, existing customers upgrading their plans, or was that money lost to cancellations? This MCP solves that by giving you granular tracking for every component of your monthly and annual recurring revenue, separating New, Expansion, and Churn streams.

You connect raw subscription data (plan price, unit count) directly to actionable financial metrics in one go. Because this is sensitive financial modeling, we built a financial circuit breaker into Vinkius; that means you set the maximum budget for these calculations, and your agent can't spend beyond it without your explicit sign-off.

The system processes time-series data through multiple specialized tools, giving you a complete picture: how fast are you growing (Net New MRR), and what is the true value of your customer base? This allows you to move past guesswork and make decisions based on solid financial signals.

Questions you might have

How does calculate_mrr work with my raw data? +

It accepts bulk subscription details—like plan price and seat counts—and outputs the definitive total MRR figure. It's designed to process a batch of data at once.

Can I use calculate_arr if I only have MRR? +

Yes, that’s exactly what the tool is for. You feed it your total MRR figure, and it converts it into an annualized revenue forecast (ARR) using established financial formulas.

What is the best way to track lost revenue? +

Use calculate_churn_impact. This tool takes your current MRR alongside a churn rate percentage, giving you a precise estimate of how much revenue you’re losing month over month.

How do I plan for next year's sales? +

Run project_revenue. This tool lets you input an initial MRR and set the desired time period, generating a forecast that shows potential revenue growth for multiple months ahead.

What are the limits when I use the `calculate_mrr` tool with a large data set? +

The MCP handles batch processing for thousands of subscriptions. While it processes massive inputs, keep in mind that performance is best if you send data in manageable chunks (under 10,000 records) to maintain speed.

Does `get_metrics_summary` provide ratios I need for operational planning? +

Yes. It generates core SaaS metrics like ARPU and Net Revenue Retention in one go. This gives you a complete snapshot of your customer value without needing to run multiple calculations.

What assumptions does the `project_revenue` tool make when forecasting? +

This tool projects revenue based on a starting MRR and a sustained growth rate percentage. It assumes linear, stable growth for the entire period, so adjust the expected rate if your sales cycle is seasonal or non-linear.

How do I ensure that `calculate_arr` remains accurate across different fiscal years? +

The tool accurately annualizes your MRR by multiplying it by 12. For true multi-year planning, you must manually account for any planned product changes or major structural shifts before running the final calculation.

What is the difference between MRR and ARR? +

MRR tracks predictable monthly revenue. To annualize this, use the calculate_arr tool. It takes your calculated MRR figure and multiplies it by twelve to give you the Annual Recurring Revenue (ARR).

How do I separate New, Expansion, and Churn revenue? +

You must first use the calculate_mrr tool to get the total MRR. Then, pass this detailed output into a subsequent aggregation step (conceptually represented by aggregate_mrr_components) to get the breakdown of New, Expansion, and Churn revenue streams.

Can I project future revenue based on current growth? +

Yes. After calculating your Net New MRR, you can use the project_revenue tool. This tool takes a starting MRR and the number of months (1-36) to generate a projected revenue total.
