Blended CAC is the total marketing spend divided by the total number of customers acquired across all channels. It gives you a single view of your acquisition efficiency.

How do I use this with Claude or Cursor?

You connect to the MCP through the Vinkius platform. Once connected, your AI client can immediately use the capabilities by simply asking it to calculate metrics or analyze trends.

Can I compare my performance to industry standards?

Yes. The budget efficiency capability compares your recent channel performance against industry benchmarks to suggest an optimal budget split.

What does a positive trend mean in the analysis?

In this MCP, a positive trend means your CAC has increased, which indicates your acquisition efficiency is worsening. A negative trend means your CAC decreased, which is an improvement.

Do I need to provide data in a specific format?

The capabilities expect spending data as a JSON array containing channel names and spend amounts. Your AI client handles the formatting when you provide the raw numbers.

What is the difference between Blended CAC and channel-specific CAC?

Blended CAC provides a single, overall average cost across all channels. To calculate this, you must use calculate_cac_metrics. This capability calculates the total spend divided by total customers, giving you the true company-wide acquisition cost.

How can I check if my marketing efficiency is getting better or worse over time?

You should use the analyze_mom_trend capability. By comparing CAC or Total Spend between two months, you get a percentage change that immediately tells you if your efficiency trend is positive (negative % change) or negative (positive % change).

How do I decide where to allocate my budget next month?

The assess_budget_efficiency capability handles this. You provide historical data, and it compares your channels' performance against industry norms to recommend an optimal percentage split for the coming period.

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

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.

Curated set · 3 capabilities
