How does this MCP handle retainage?

The MCP calculates retainage based on the rates you define and applies it to each milestone payment automatically.

Can I use this with Claude or Cursor?

Yes, you can connect this MCP to any MCP-compatible client including Claude, Cursor, and Windsurf.

What happens if I have a deposit?

The MCP includes deposits in its calculations to ensure the remaining contract balance and milestone payments are accurate.

How do I know the payment math is correct?

You can use the validate_milestone_logic capability to check if your proposed payments match the contract terms.

How does the capability handle change orders?

Change orders are treated as adjustments to the original contract total. The capabilities incorporate these values to recalculate the adjusted contract value and all subsequent milestone payments.

What is retainage in these calculations?

Retainage is the percentage of each milestone payment held back by the client. The get_milestone_schedule capability calculates both the amount held and the net payment released to the contractor.

Can I verify if my payment plan is correct?

Yes, you can use the validate_milestone_logic capability to check if a proposed set of milestones and payments is mathematically consistent with your contract terms.

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.

How Vinkius works: one connection, every tool, in any AI

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.
