Run Real-Time Tax Base Operations with Vercel AI SDK

The `get_taxable_base` tool calculates your presumptive tax foundation instantly using gross revenue and industry activity types. This tool feeds raw financial figures directly into your active UI stream so users see their tax brackets update without waiting for page refreshes. You configure this setup by calling the standard initialization methods inside your Edge Functions. It keeps your client-side application lightweight while running intensive fiscal math behind the scenes.

Calculate Exact CIT Breakdown for Live Next.js Views

The `calculate_cit_breakdown` tool computes the standard fifteen percent corporate income tax along with any ten percent surtaxes. Your AI client pulls these figures on the fly to render clean, interactive charts for your users. Because this MCP handles the complex Brazilian tax rules natively, your application code stays clean. You avoid writing messy math libraries inside your React components.

Display Live SCLL Liabilities and Summary Reports

The `calculate_scll_liability` tool handles the nine percent social contribution math, while the `generate_tax_summary_report` tool aggregates all liabilities into a single structured payload. This allows your interface to present complete financial summaries as they stream from the model. Users get instant clarity on their total tax burden without staring at loading spinners. This MCP integration makes financial planning tools feel fast and responsive.

Active Vinkius subscription with a valid endpoint token

1

Install dependencies

Run npm install ai @modelcontextprotocol/sdk plus your preferred model provider (e.g. @ai-sdk/openai).
2

Create the Streamable HTTP transport

Use StreamableHTTPClientTransport with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.

Works with any model provider

Swap openai("gpt-4o") for any AI SDK provider — Anthropic, Google, Mistral. The MCP tools work identically across all supported models.

index.ts

import { experimental_createMCPClient as createMCPClient } from "ai";
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp";
import { generateText } from "ai";
import { openai } from "@ai-sdk/openai";

const transport = new StreamableHTTPClientTransport(
  new URL("https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp")
);

const mcpClient = await createMCPClient({ transport });
const tools = await mcpClient.tools();

const { text } = await generateText({
  model: openai("gpt-4o"),
  tools,
  prompt: "List recent Presumed Profit Tax Calculator transactions",
});

console.log(text);
await mcpClient.close();
