# Providers

> The connector catalog — registered sources, sinks, and their config schemas.

Defined in `api/ingestion/v1/providers.proto`. This is how the UI (or any
other client) discovers what connectors are available without a hardcoded
list — it reflects whatever is currently registered via blank import (see
[Connectors overview](/pages/connectors/overview/introduction)).
