Hunting down state interest rates is a mess.
Right now, if you need to know the interest on a debt, you have to open a dozen tabs. You're hunting for state statutes, trying to figure out if they use simple or compound interest, and then pulling out a calculator to count the days between two dates. It's tedious, and it's easy to make a mistake that costs you money.
With this MCP, you just tell your agent what you need. It pulls the rules for the specific state, handles the date math, and gives you the final number. You skip the research slog and get straight to the data you actually need.
US Pre-judgment Interest Calculator lets you skip the research.
You no longer have to manually search for statutes or calculate day counts in a spreadsheet.
You just get the final interest amount based on real state law. It's that simple.
What you can do with this MCP connector
This MCP takes the headache out of figuring out how much interest a debt has racked up across different states. If you're dealing with a legal claim or a debt portfolio, you usually have to jump between multiple tabs to find out if a state uses simple or compound interest, what the current rate is, and how many days have passed since the default date.
It's a lot of manual work where a single mistake in date counting or picking the wrong statute can mess up your entire calculation. This MCP gives your agent the ability to pull those specific rules and run the math for you in one go. You can ask it to check the rules for a specific state, like New York or Texas, and then have it calculate the total interest based on the debt amount and the dates you provide.
It handles the date arithmetic automatically, so you don't have to worry about leap years or specific day counts. Because Vinkius hosts this tool, you can plug it into your existing setup and get these answers instantly during your research. It's designed for people who need accuracy without the manual slog of digging through legal databases.
You get the specific numbers you need, grounded in state-specific statutes, without having to do the math yourself. It's about getting reliable data for your legal filings or financial models without the risk of human error in the middle of the process. You can stop worrying about the underlying math and focus on the actual work of your case.

The Tradeoffs
Guessing the interest rate
Assuming a state uses a standard rate like 5% without checking current laws.
→
Use get_state_statute_details to pull the actual legal rate for the specific state instead of guessing.
Manual date counting
Trying to count the days between two dates in a spreadsheet and getting leap years wrong.
→
Use calculate_accumulated_interest to handle the date arithmetic automatically.
Using simple interest for all states
Assuming every state uses simple interest without checking the statute.
→
Use get_state_statute_details to confirm if the state requires simple or compound interest.
When It Fits, When It Doesn't
Use this if you need accurate, research-based interest calculations for US states. It's perfect for legal research, preliminary financial modeling, and debt analysis where state-specific statutes matter. Don't use it if you need real-time municipal-level data, like specific city ordinances, as it focuses on state-level law. If you just need a general bank interest calculator for a savings account, a standard finance tool is a better fit. This MCP is specifically for statutory pre-judgment interest and should be used when you need the legal rules applied to the math.
