Explore MotherDuck Data
Use this skill when you need to discover what databases, tables, and columns exist in a MotherDuck account; preview and sample data; understand schemas and data types; find shared databases; or search the data catalog.
Prerequisites
- Establish a MotherDuck connection first via
motherduck-connect.
Default Posture
- Explore top-down: databases, then tables/views, then columns, then statistics, then sample rows.
- Use fully qualified table names once more than one database is attached.
- Check shared databases before concluding that data is unavailable.
- Use MCP exploration tools when available because they return structured results faster than ad hoc SQL.
- Return a concise schema map with table grain, join keys, date columns, and likely measures before moving into modeling or dashboard work.
Workflow
- List databases in scope.
- List tables and views in the target database.
- Inspect columns, types, nullability, and comments before writing queries.
- Run
SUMMARIZEon important tables to understand ranges, cardinality, and null rates. - Preview rows, capture grain and join assumptions, and only then move into analytical SQL or modeling work.
