Calculate base tax liabilities

Windsurf reads your financial data structures and fires off calculations autonomously. If your client falls under the Lucro Presumido regime, Cascade pulls the gross revenue figures and runs `calculate_cumulative_tax` to get the base liability. You get hard numbers back instantly. No switching to spreadsheets. The agent injects the exact tax burden directly into your financial reporting scripts.

Model non-cumulative credits

High-input entities need to track deductible credits. Your agent evaluates the raw input costs against the revenue stream. It executes `calculate_non_cumulative_tax` to determine the net liability under the Lucro Real framework. This is where companies bleed cash if they get it wrong. Windsurf chains these steps. You ask for the tax breakdown, and Cascade figures out the credit math before showing you the bottom line.

Compare regimes with Windsurf

Picking the wrong tax regime destroys profit margins. You need a side-by-side view. Just tell your AI client to run `evaluate_regime_comparison` against your quarterly historical data. The agent maps out the breakeven points using this MCP Server. You see exactly when the administrative cost of credit management wipes out the tax savings. Run the numbers first.

Yes. Cascade autonomously selects the correct tax calculation based on your prompt. Just specify if you need Lucro Real or Lucro Presumido numbers.

It does. You provide the revenue and input costs. The agent compares both regimes and spits out the most profitable option.

Cascade chains multi-step actions. You set a goal to audit your Brazilian tax liabilities, and the agent plans the sequence, executes the calculations, and formats the output without asking for permission at every step.

Your gross revenue and input credit figures stay local to your environment. This MCP only processes the numbers you feed it to calculate statutory rates. No data leaves your machine unless you explicitly log it.
