What It Does

The Inquisitor compiles a comprehensive data quality test suite from schema definitions and historical data patterns. It generates dbt-compatible tests (not_null, unique, accepted_values) plus custom statistical tests (distribution checks, outlier detection). It learns what "normal" looks like for each field to set intelligent thresholds.

Capabilities

dbt-compatible test generation
Statistical threshold learning
Distribution checks
Outlier detection
Referential integrity tests
Freshness checks
Custom rule generation

Example

inquisitor-example.ts

const result = await mcp.call('inquisitor_generate_tests', {
  source_id: 'salesforce-contacts',
  schema: phantomResult.inferred_schema,
  historical_data: true,
});
console.log(result.test_count);  // 47
console.log(result.test_suite);  // dbt YAML test definitions
