The Developer Knowledge API and MCP server can search and get documents from public pages in the following domains:

• adk.dev
• ai.google.dev
• antigravity.google
• cloud.google.com
• dart.dev
• developer.android.com
• developer.chrome.com
• developers.home.google.com
• developers.google.com
• docs.apigee.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

Data freshness

The Developer Knowledge API aims to provide access to the latest Google developer documentation. Our goal is to re-index content within 48 hours of publication so that new or updated documentation is available within 2 business days.
