Get a Full Tax Picture in One Go

Stop running tax calculations one by one. Just give Cascade your gross revenue and activity type. It will figure out the right steps to run the numbers. Cascade automatically calls `get_taxable_base`, then `calculate_cit_breakdown` and `calculate_scll_liability` in the correct sequence. You don't prompt each step; you just get the final numbers.

Generate Tax Reports with a Single Prompt

Need to turn raw revenue data into a shareable report? Tell Windsurf what you need. It's smart enough to know that a report requires running all the preliminary calculations first. Your agent chains all the necessary tools and finishes by calling `generate_tax_summary_report`, giving you a complete, consolidated file without you ever touching the individual calculation tools.

Run What-If Scenarios with your Windsurf MCP Server

This MCP Server lets you quickly model different financial scenarios. You can ask Windsurf to compare tax outcomes for different revenue numbers or business activities. Cascade handles the repetitive work, running the full chain of calculations for each scenario you define. It's a fast way to see how changes impact your bottom line.

Common questions about Presumed Profit Tax Calculator MCP in Windsurf

You just ask Windsurf for a tax summary. Its Cascade agent automatically plans and executes the steps: it gets the taxable base, calculates CIT and SCLL, and then generates the final report. You don't have to call the tools individually.

Yes. Just give Windsurf a few different revenue numbers. It will run the full calculation sequence for each one, letting you compare the final tax liabilities side-by-side.

The main benefit is automation. With the Presumed Profit Tax Calculator, Windsurf's Cascade agent can perform the entire tax calculation workflow from a single prompt, saving you from manual, step-by-step calculations.

It does. The calculation for the taxable base depends on the activity type you provide. The MCP uses standard presumptive margins: 32% for services and 8% for commerce.

Your financial inputs, like gross revenue and activity type, are sent directly to the Vinkius-managed MCP. The connection is encrypted, and the data is only used for the calculation you requested. It's not stored or used for anything else.
