Analyze an A/B test experiment and provide a clear ship/iterate/no-ship recommendation. Use when evaluating experiment results.
Run correlation analysis on connected data, identify strong relationships, and suggest regression models. Use when exploring relationships between variables.
Run an end-to-end data analysis pipeline — connect, profile, analyze, and report. Use when performing a complete analysis workflow.
Connect to a data source, profile its schema and quality, and recommend appropriate analyses. Use when starting work with a new dataset.
Analyze a time series and generate forecasts with confidence intervals. Use when predicting future values from historical data.
Explore a graph or network dataset — structure, statistics, paths, and visualization. Use when working with DOT, GML, GraphML, or Mermaid files.

Find natural groupings in data using multiple clustering approaches, evaluate quality, and interpret results.
Explore features. Call describe_database with the database name from $ARGUMENTS. Identify numeric columns suitable for clustering. Note any categorical columns that could provide context for interpreting clusters later.
Extract and review data. Call execute_query to select the numeric feature columns. Check for nulls and extreme outliers in the sample. Note the number of observations and features.
Run K-Means clustering. Call analyze_clusters with the database name, feature columns, and algorithm set to "kmeans". Start with k=3 unless domain knowledge suggests otherwise. Review the silhouette score and cluster sizes.
Try alternative k values. If the silhouette score is below 0.5, re-run analyze_clusters with k=2, k=4, and k=5. Compare silhouette scores to find the optimal number of clusters.
Run DBSCAN for comparison. Call analyze_clusters with algorithm set to "dbscan". This density-based approach does not require specifying k and can find irregularly shaped clusters. Compare the number of clusters found and the noise point percentage.
Evaluate and compare. Assess both approaches:
Reduce dimensions for visualization. Call reduce_dimensions with the database name and feature columns, using PCA with 2 components. This provides a 2D representation of the clusters for interpretation.
Interpret clusters. For the best clustering result, describe each cluster by its feature averages. Give each cluster a descriptive label based on its defining characteristics. Note which features most differentiate the clusters.
Present results. Provide:
Recommend next steps. Suggest using cluster labels as a feature in /localdata-mcp:regression, running /localdata-mcp:analyze-correlations within each cluster, or applying the clustering to new data for segmentation.
