When you create an agent in MindsDB that connects to one of the supported integrations, the Data Catalog automatically:
Inspects the data source.
Extracts metadata for all accessible tables and columns.
Stores this information in a dedicated catalog schema (DATA_CATALOG).
Makes this metadata available to agents and users via both SQL queries and internal reasoning.
Current LimitationsThis feature is still evolving and has some known limitations:
One-Time Snapshot: Metadata is generated only once—at the time the agent is created. If the data schema changes (e.g., new columns, renamed tables), the Data Catalog will not automatically update. A refresh mechanism is planned in a future release.
No Manual Feedback: If any metadata appears to be incorrect (e.g., wrong row counts or data types), there is currently no way for users to flag or correct it. A feedback system will be introduced soon.
