How do I use this with Claude?

You connect the MCP through the Vinkius platform. Once connected, your agent in Claude can call the tax capabilities directly.

Can I calculate weekly pay?

Yes. The MCP includes a specific capability for calculating weekly PAYE deductions.

Does it handle National Insurance?

Yes. The calculations include both Income Tax and National Insurance deductions.

What is a tax code allowance?

It is the amount of income you can receive before you start paying tax. This MCP can translate your code into that specific amount.

Do I need to provide my tax code?

For the most accurate results, you should provide your specific HMRC tax code so the agent can calculate your exact deductions.

How do I calculate my monthly take-home pay?

You can use the calculate_monthly_paye capability. Simply provide your annual gross salary and your UK tax code (e.g., 1257L) to get a breakdown of monthly net pay, income tax, and NI deductions.

A UK tax code is an alphanumeric identifier used by HMRC to specify your personal allowance. You can use the get_tax_code_allowance capability to find out how much income you can earn before paying tax based on your code.

Does this capability include National Insurance deductions?

Yes, both the weekly and monthly calculation capabilities automatically calculate your National Insurance contributions based on current UK thresholds.

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
