Compare business structures inside Cursor

The `calculate_tax_comparison` tool lets your development agent pull real tax calculations directly into your workspace. Stop writing mock financial models when you can generate working code that reflects actual federal and state tax liabilities. The agent evaluates different corporate structures instantly. It injects real math into your business planning files instead of placeholder calculations.

Model S-Corp savings with this MCP Server

Use `evaluate_s_corp_savings_potential` to calculate the exact tax savings tipping point for your business. Deciding when to switch to an S-Corp is a math problem where timing is everything. Your agent compares self-employment tax drag against payroll setup costs. It helps you avoid transitioning too early or overpaying self-employment taxes.

Fetch local tax contexts as you write code

The `get_state_tax_context` tool fetches active state tax environments directly into your editor using this MCP Server. State tax compliance is a moving target, and you cannot rely on hardcoded rates when building financial tools. Your agent pulls current local tax rules directly into your active coding file. You get real-time state tax data without leaving your terminal.
