Live Regular Method processing

Calculate your potential tax savings instantly by passing financial data into `calculate_regular_method_credit`. This MCP provides immediate feedback that your React or Next.js components can render as the numbers arrive. Stop forcing users to wait for batch jobs. By hooking this logic into your edge functions, you show the calculation results the moment the data is ready.

Alternative Simplified Credit streaming

Use `calculate_asc_method_credit` to determine your eligibility under the ASC methodology. The typed response flows right into your UI state management. Your frontend stays responsive while the math happens behind the scenes. It turns complex tax logic into a fluid user experience.

Automated strategy comparison

Run `recommend_optimal_tax_strategy` to let your agent decide between the two methodologies. You get the final recommendation without manual comparison loops. This keeps your application logic clean. You provide the inputs, and the agent delivers the optimal tax path directly to your dashboard.

Setup guide

Set up R&D Tax Credit Calculator MCP in Vercel AI SDK

Prerequisites

Node.js 18+ and a TypeScript project
ai + @modelcontextprotocol/sdk packages
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.
3

Discover and use tools

Call mcpClient.tools() to auto-discover all R&D Tax Credit Calculator tools. Pass them directly to generateText() or streamText() — no manual schema definitions needed.
4

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 R&D Tax Credit Calculator transactions",
});

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