Automate Calculations in Claude Code

Claude Code executes `calculate_tax_liability` from the command line to generate exact federal and state tax breakdowns for any profit figure. You pipe these results directly into your backend reporting scripts. The headless execution means you can run bulk calculations across thousands of revenue scenarios. Your agent handles the math silently in the background.

Process Entity Comparisons

This MCP evaluates entity types in your terminal by running `compare_business_structures` to output side-by-side tax burdens for C-Corps, S-Corps, and LLCs. You integrate these comparisons into your automated financial pipelines. The agent processes the structural analysis and outputs raw data for your downstream systems.

Pull State Data via MCP Server

Your agent queries `get_state_tax_rate` to pull hardcoded corporate income percentages for specific jurisdictions. It feeds these exact rates into your cron jobs or deployment checks. You automate the state-level variables without maintaining manual lookup tables.
