Chi-Square Test Engine MCP Server for Claude CodeGive Claude Code instant access to 1 tools to Calculate Chi Square

The Chi-Square test determines whether two categorical variables are independent. Asking an LLM to compute expected frequencies across a matrix and then sum the chi² residuals is a recipe for hallucinated results.

Claude Code registers Chi-Square Test Engine as an MCP server in a single terminal command. Once connected, Claude Code discovers all 1 tools at runtime and can call them headlessly. ideal for CI/CD pipelines, cron jobs, and automated workflows where Chi-Square Test Engine data drives decisions without human intervention.

This MCP computes the full test deterministically using jstat. The AI sends the observed frequency matrix, and the engine calculates exact expected frequencies, the chi² statistic, degrees of freedom, and the p-value — all locally on your CPU.

The Superpowers

• Zero Hallucination: Exact chi² statistics computed deterministically.
• Automatic Expected Frequencies: The engine builds the entire expected matrix internally.
• Any Matrix Size: Supports 2x2, 3x3, or larger contingency tables.
• Data Privacy: Your survey and business data stays local.

The Chi-Square Test Engine MCP Server exposes 1 tools through the Vinkius. Connect it to Claude Code in under two minutes — credentials fully managed, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
