The headache of manual debt recovery.
You're sitting with a pile of late invoices. To figure out what to charge, you have to open a browser to check the current Bank of England base rate. Then you have to do the math to add the 8% markup. After that, you have to hunt down the specific compensation brackets for different debt sizes. You're copy-pasting numbers into a spreadsheet and hoping you didn't miss a decimal point.
This MCP changes that. You just tell your agent the debt amount and the date it was due. It does the math, checks the rates, and gives you the final number. You get a clear answer in seconds instead of a spreadsheet full of potential errors.
Get accurate UK debt claims with UK Statutory Interest Calculator
No more manual lookups for base rates. No more hunting for compensation brackets. No more manual interest formulas.
You get precise, legally-grounded figures for every late payment. It turns a tedious research task into a single command.
What your AI can actually do with this
The UK Statutory Interest Calculator MCP handles the math for late commercial payments in the UK. When a client owes you money and they're late, you need to know exactly what they owe you beyond the original invoice. Dealing with the UK's Late Payment of Commercial Debts Act 1998 usually means digging through spreadsheets to figure out the current Bank of England base rate, adding the 8% markup, and then checking the specific compensation brackets for different debt sizes.
It's a headache that's easy to mess up, especially when you're dealing with dozens of different accounts. This MCP takes that math off your plate. You just tell your agent how much is owed and when it was due, and it handles the heavy lifting. It's built for people who need to get paid without the manual calculation errors that come from copy-pasting numbers between tabs.
Because it's part of the Vinkius catalog, you can pull this into your existing workflow without setting up complex new infrastructure or writing custom scripts. It turns a multi-step math problem into a one-sentence request. Instead of spending ten minutes per invoice verifying rates and doing arithmetic, you get a precise answer in a few seconds.
You get your money back faster and with more confidence that the numbers you're asking for are actually correct under UK law.

See it in action
Calculating interest on a late invoice
An AR clerk asks for the interest on a £2,000 debt from last month. The agent uses accrued_interest to give the exact amount.
Finding the compensation fee for a large debt
A debt agent asks for the compensation fee on a £15,000 invoice. The agent uses compensation_fee to find the fixed amount.
Generating a final demand summary
A business owner needs a full summary of a £5,000 debt to send a final notice. The agent uses total_claim_summary to provide a complete breakdown.
Auditing a batch of late payments
A legal clerk is auditing a batch of late payments. They ask for the total claim value for a list of debts. The agent calculates these values one by one.

When It Fits, When It Doesn't
Use this if you need to calculate statutory interest and compensation fees for commercial debts in the UK. It's a foundation for domestic summaries. Don't use it if you just need to calculate simple interest, multi-currency conversions, or tax-related deductions. If you're outside the UK, this MCP won't work because it's tied to specific UK legislation. For general finance math without legal requirements, a basic calculator tool is better. Use accrued_interest for specific interest amounts, compensation_fee for the fixed amounts, and total_claim_summary for a full breakdown.
