Calculate tax logic in Cursor

Write your financial modules faster by letting the agent run `calculate_cumulative_tax` for you. It pulls the numbers you need while you are busy editing files. This keeps your implementation accurate by using real calculation logic rather than guessing the math.

Automate non-cumulative assessments

Plug `calculate_non_cumulative_tax` into your workflow to verify your tax logic in real time. You get the net liability returned directly to your editor. This prevents errors in your code by validating your tax structures against live calculation tools.

Compare regimes during development

The `evaluate_regime_comparison` tool lets you test different tax scenarios right in the chat. You can see the impact of your changes before you commit any code. It helps you build robust financial features by showing you exactly how the tax math behaves under both regimes.

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".

Common questions about PIS/COFINS Tax Calculator MCP in Cursor

Define the MCP in your .cursor/mcp.json file. Once configured, enable Agent mode in your chat to start using the tools within your project.

Absolutely, the agent can call these tools to fetch tax data for your code. It works by executing the calculation and presenting the result for your review.

Yes, you can prompt the agent to write code that incorporates the results from these tax tools. It helps you build automated reports or tax-aware software modules.

The tools perform calculations based on standard tax rules. You can trust the output for your development and testing needs.

Your raw tax data is processed in memory during the agent's turn. The connection is ephemeral, meaning your financial inputs are not retained beyond the immediate calculation session.
