Before you connect
Questions about finance-toolkit.
The practical details behind the request, access and result.
Can the Finance Toolkit MCP handle different loan types?
Yes, it supports both SAC and PRICE loan tables, allowing you to compare different repayment structures easily.
Is my financial data safe with the Finance Toolkit MCP?
Yes, the Connector runs locally on your machine, so your sensitive financial data never leaves your infrastructure.
Can the Finance Toolkit MCP do compound interest?
Yes, it can calculate compound interest over any period with customizable frequencies for accurate growth projections.
How accurate are the results from the Finance Toolkit MCP?
The results are 100% deterministic because the math is handled by a V8 Javascript engine rather than an LLM guess.
Can the Finance Toolkit MCP calculate marketing ROI?
Yes, it can calculate the Return on Investment percentage for any project, including marketing spend and asset sales.
Why doesn't the amortization capability return the full 360-month table?
Returning 360 lines of JSON would severely bloat the LLM's context window, increasing API costs and causing distraction. We return a "Smart Summary" (total paid, total interest, first and last installments) which is perfect for AI decision-making.
Are the compound interest calculations precise enough for banking?
Yes. The underlying engine relies on JavaScript's high-precision floating-point arithmetic (IEEE 754 standard). Outputs are rounded to 2 decimal places specifically for financial display standards.
Can it compare SAC vs PRICE automatically?
An AI agent using this Connector can execute the capability twice in parallel—once for SAC and once for PRICE—and instantly write a comparative analysis report for you based on the exact totals.
