Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Who it's for

Built for the work MRR and ARR Calculator owners hand off.

This MCP is built for finance professionals and SaaS operators who need to turn raw billing data into strategic insights.

  • 01

    SaaS Founders

    You hand off raw subscription counts to your agent to monitor growth and churn.

  • 02

    Finance Analysts

    You use the agent to run complex revenue projections and metric summaries.

  • 03

FAQ

Questions MRR and ARR Calculator owners ask.

  • 01

    What can this MCP calculate?

    It calculates MRR, ARR, churn impact, and projected revenue. It also provides summarized SaaS metrics like ARPU.

  • 02

    How do I use it with Claude or Cursor?

    You connect to the Vinkius-hosted MCP once. After that, you can simply ask your AI client in Claude or Cursor to perform revenue calculations using the capabilities provided.

  • 03

    Do I need to provide my own billing data?

    Yes, you provide the raw subscription data, such as plan prices and seat counts, which your agent then processes using the MCP capabilities.

  • 04

    Can it help with forecasting?

    Yes, the project_revenue capability allows your agent to create revenue projections for any given time period.

  • 05

    Is this for any type of subscription business?

    It is designed for SaaS and any business model using recurring revenue models that track plan prices and unit counts.

  • 06

    What is the difference between MRR and ARR?

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

  • 07

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

    You must first use the calculate_mrr capability 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.

  • 08

    Can I project future revenue based on current growth?

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