How to Use the Chi-Square Test Engine MCP in Mastra AI

Q: Can I use Chi-Square Test Engine within Mastra AI workflows?

Yes. You can call the calculatechisquare tool as a step inside your Mastra workflows, allowing you to branch your logic based on the returned p-value.

Q: Does this server handle Yates' correction for 2x2 tables?

Yes, the calculatechisquare tool applies standard statistical corrections where appropriate to ensure your categorical analysis remains accurate even with small cell counts.

Q: Does Mastra AI leak my raw frequency tables to third parties?

No. The categorical counts sent to the calculatechisquare tool go straight to a secure, isolated Vinkius sandbox. Your raw data is processed in memory and wiped immediately after the calculation.

Run deterministic statistical workflows in Mastra AI without LLM math errors.

Automated statistical branching in Mastra AI

Mastra AI excels at complex workflows. When your agent needs to decide whether two categorical variables are independent, it can invoke the `calculate_chi_square` tool via this MCP Server. If the resulting p-value is below your alpha threshold, your workflow can automatically branch to trigger an alert. If not, it logs the null hypothesis and continues.

Fault-tolerant statistical pipelines

Network hiccups shouldn't break your data pipelines. This MCP Server integrates with Mastra's built-in retry engine to handle temporary connection drops smoothly. When your workflow calls `calculate_chi_square`, Mastra handles exponential backoffs behind the scenes. You get reliable, deterministic statistics without writing manual retry loops.

Human-in-the-loop validation for critical tests

Sometimes you don't want an agent acting on statistical tests blindly. You can configure Mastra to require human approval before executing major actions based on the test results. The `calculate_chi_square` tool runs the math, presents the raw chi² value and p-value, and waits for a team member to approve the next step in the workflow.

Setup guide

Set up Chi-Square Test Engine 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 Chi-Square Test Engine 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: "chi-square-test-engine-mcp-client",
  servers: {
    "chi-square-test-engine-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "Chi-Square Test Engine Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to Chi-Square Test Engine tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent Chi-Square Test Engine transactions"
);
console.log(result.text);

Common questions about Chi-Square Test Engine MCP in Mastra AI

You initialize the MCP client in your TypeScript code and register the server URL. Then, you pull the `calculate_chi_square` tool and register it directly in your agent's tools array.

Yes. You can call the `calculate_chi_square` tool as a step inside your Mastra workflows, allowing you to branch your logic based on the returned p-value.

Yes. Mastra automatically manages the connection lifecycle to the MCP Server. If a request to `calculate_chi_square` fails due to network issues, Mastra's built-in retry mechanism takes over.

Yes, the `calculate_chi_square` tool applies standard statistical corrections where appropriate to ensure your categorical analysis remains accurate even with small cell counts.

No. The categorical counts sent to the `calculate_chi_square` tool go straight to a secure, isolated Vinkius sandbox. Your raw data is processed in memory and wiped immediately after the calculation.
