Rigor MCP Overview

The rigor-mcp MCP server provides computed, cited statistical inference for AI agents, including hypothesis tests, effect sizes, power analysis, corrections, and sequential testing. It exposes decision and batch helpers alongside tools for t-tests, proportions, categorical data, correlations, regression, and non-parametric methods. Results include statistical details, confidence intervals where supported, citations, and assumption warnings. Reach for it when an agent must calculate results from supplied data rather than recall a similar textbook example.

Primary Use Cases for Rigor MCP:
  • Run assumption-checked hypothesis tests on supplied sample data
  • Calculate power or required sample size for planned experiments
  • Correct a batch of pairwise comparisons for multiple testing
  • Select a statistical test from data and study characteristics
