Connect your AI to Brazilian market data once. From then on, your agent handles the math and tax calculations for you.

Short answer

Which Brazilian fixed income asset has the highest net return?

Your AI compares the gross yields of different Brazilian instruments and subtracts the specific tax rates for each. You get a clear ranking of what actually hits your bank account after the government takes its cut. This breakdown shows the real profit for every asset you're looking at.

FAQ

How this task behaves

  • 01

    Does the AI execute the actual trades for me?

    No. The AI only calculates and compares the returns. You must execute any trades through your own brokerage or bank.

  • 02

    Can the AI change my tax settings?

    No. The AI only reads the tax rules to perform calculations. It cannot modify your personal tax profile or account settings.

  • 03

    How does it know which tax rate to use?

    The AI uses the specific tax rules associated with each Brazilian instrument type to calculate the net return.

  • 04

    Can I compare assets from other countries?

    No. This specific tool is built to handle the specific tax and yield structures of Brazilian fixed income assets.

  • 05

    Will the AI remember my previous comparisons?

    The AI's memory depends on your specific AI client's chat history, not the MCP itself.
