The Developer Knowledge API and MCP server can search and get documents from public pages in the following domains:
- adk.dev
- ai.google.dev
- developer.android.com
- developer.chrome.com
- developers.home.google.com
- developers.google.com
- docs.apigee.com
- docs.cloud.google.com
Exceptions
Pages with the following prefixes are not included in the corpus:
- docs.cloud.google.com/cpp/docs/reference
- docs.cloud.google.com/dotnet/docs/reference
- docs.cloud.google.com/go/docs/reference
- docs.cloud.google.com/java/docs/reference
- docs.cloud.google.com/nodejs/docs/reference
- docs.cloud.google.com/php/docs/reference
- docs.cloud.google.com/python/docs/reference
- docs.cloud.google.com/ruby/docs/reference
- docs.cloud.google.com/rust/docs/reference
- firebase.google.com
- fuchsia.dev
- go.dev
- web.dev

These domains are the only valid values to use for data_source in the
SearchDocumentChunks.filter
field, for example: data_source = "docs.cloud.google.com".
Data freshness
The Developer Knowledge API aims to provide access to the latest Google developer documentation. Our goal for data freshness is to re-index content within 24-48 hours of its publication. This means that newly published or updated documentation should be available through the API within 1-2 business days.
