The `calculate_amortization` tool processes loan data locally to generate exact payment schedules. You provide the principal, term, and interest rate, and the engine returns the precise split between interest and principal. This keeps your litigation financials accurate by avoiding manual spreadsheet errors. It handles the math for both constant amortization and French models within your Claude Desktop session.

Stop jumping between your browser and local financial software. By integrating this MCP Server, your agent performs complex real estate interest projections without leaving the chat interface. Everything happens in real-time, allowing you to iterate on settlement figures instantly. The engine outputs structured data that you can immediately feed into your legal documents.

Secure local financial processing

Your data never leaves your machine when using local stdio transport.
