Map Taxable Bases Automatically in Mastra AI Workflows

The `get_taxable_base` tool determines the presumptive margins for your commerce or service business within your automated agents. Mastra AI uses these calculations to route financial files to the correct processing steps. If a calculation fails due to network hiccups, the workflow engine triggers automatic retries with exponential backoff. This ensures your tax pipelines never stall on temporary errors.

Calculate SCLL Liabilities with Built-in Agent Retries

The `calculate_scll_liability` tool computes the nine percent social contribution liability directly within your agentic workflows. Your agent can evaluate this output to decide if human approval is needed before filing. You configure these decision branches using simple TypeScript code. The MCP handles the math while Mastra manages the execution state.

Generate Complete CIT Breakdowns and Summary Reports

The `calculate_cit_breakdown` tool handles the fifteen percent standard tax and surtaxes, while the `generate_tax_summary_report` tool packages everything into a final ledger. Your agents can run these tools sequentially to prepare monthly tax filings. This MCP setup allows you to deploy fully autonomous tax prep assistants to any cloud provider. The system handles complex Brazilian corporate tax rules without manual intervention.

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3
