cdc_discover_datasets
Search the CDC dataset catalog by keyword, category, or tag. Returns dataset IDs, names, descriptions, column lists, and update timestamps. Use this first to find the right dataset before querying.
cdc_get_dataset_schema
Fetch the full column schema for a CDC dataset — names, data types, descriptions, row count, and last-updated timestamp. Essential before writing SoQL queries against unfamiliar datasets.
cdc_query_dataset
Execute a SoQL query against any CDC dataset. Supports filtering, aggregation, sorting, full-text search, and field selection. Use cdc_discover_datasets to find dataset IDs and cdc_get_dataset_schema to inspect columns before querying.
Tip — enumerate column values: use select: "{column}, count(*) as count", group: "{column}", order: "count DESC" to see distinct values.
