Finding the exact Pearson correlation between 10 numeric columns requires computing 45 unique pairwise coefficients with perfect floating-point precision. No LLM can do this reliably.

This MCP delegates the computation to simple-statistics running locally. The AI passes a dictionary of named columns, and the engine builds the complete NxN correlation matrix, automatically extracting the top 5 strongest correlations.

The Superpowers

  • Zero Hallucination: CPU-computed coefficients with perfect precision.
  • Full NxN Matrix: Generates the complete correlation table across all column pairs.
  • Top-5 Extraction: Automatically surfaces the strongest relationships.
  • Data Privacy: Your sensitive data stays entirely local.

Find the exact Pearson correlation between all columns in this housing dataset.

The strongest relationship is between SquareMeters and Price (r = 0.89). The top 5 correlations have been extracted for your review.

Which features are most correlated with customer churn?

The strongest correlations with churn are: MonthlyCharges (r = 0.72), ContractLength (r = -0.68), and SupportTickets (r = 0.54).

Generate a Spearman matrix for this clinical trial data.

Strong monotonic relationship between Dosage and Response (ρ = 0.81). Age and Response show weak correlation (ρ = 0.12).

Pearson measures linear relationships and assumes normally distributed data. Spearman is rank-based, making it robust against outliers and ideal for non-linear monotonic relationships.
