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.
Discover natural groupings in data using clustering algorithms with evaluation and visualization. Use when segmenting data or finding patterns.
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.
Explore a graph or network dataset — structure, statistics, paths, and visualization. Use when working with DOT, GML, GraphML, or Mermaid files.

Decompose a time series, test for stationarity, and generate forecasts with confidence intervals.
Parse arguments. Extract the database name and target column name from $ARGUMENTS. The first argument is the database name, the second is the column to forecast.
Query the time series. Call execute_query to select the datetime column and the target column, ordered by time ascending. If the table is not obvious, query the schema first. Ensure no gaps in the time index. Limit to the most recent 10,000 observations if the series is very long.
Analyze the series. Call analyze_time_series with the database name and column. Review the decomposition results:
Interpret the analysis. Summarize the time series characteristics:
Generate forecasts. Call forecast_time_series with the database name, column, and desired forecast horizon. The tool will select an appropriate model (ARIMA, ETS, or SARIMA) based on the series characteristics. Request confidence intervals at the 80% and 95% levels.
Present the forecast. Display results in a structured format:
Assess forecast reliability. Comment on:
Recommend next steps. Suggest monitoring actual values against forecasts, re-fitting when new data arrives, or running /localdata-mcp:analyze-correlations to find external predictors that could improve the model.
