Fetch State Rules Reliably

Executing `get_state_tax_context` retrieves the specific tax environment details for a target jurisdiction. Mastra AI wraps this request in automatic retries with exponential backoff if the network stutters. Building financial tools requires fault tolerance. Your agent will keep trying until it secures the correct local filing requirements from the MCP.

Branch Logic on Savings

The `evaluate_s_corp_savings_potential` action determines exactly how much a founder saves by electing S-Corp status. You can configure conditional branching to email an accountant only if the FICA savings exceed a specific dollar threshold. Complex decision trees run natively via this MCP integration. The agent evaluates the salary model and triggers the next step automatically.

Deploy the Tax MCP Server

Triggering `calculate_tax_comparison` generates a side-by-side breakdown of federal and state liabilities for multiple entity types. Pushing this logic to production takes exactly one command with Mastra. Cloud deployment usually creates headaches for custom Python scripts. Connecting to Vinkius bypasses the infrastructure setup entirely.

Setup guide

Set up US LLC Tax Comparator MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

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

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All US LLC Tax Comparator tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "us-llc-tax-comparator-mcp-client",
  servers: {
    "us-llc-tax-comparator-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "US LLC Tax Comparator Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to US LLC Tax Comparator tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent US LLC Tax Comparator transactions"
);
console.log(result.text);
