Google is previewing the Developer Knowledge API and an associated Model Context Protocol (MCP) server, which together offer a machine-readable gateway to the company’s official developer documentation.

Announced February 4, the Developer Knowledge API is designed to be the programmatic source of truth for Google’s public documentation. Developers can access documentation from firebase.google.com, developer.android.com, docs.cloud.google.com, and other locations. Developers can search and retrieve the documentation pages as Markdown.

The companion MCP server gives AI-powered development tools the ability to “read” Google developer documentation, enabling more reliable features such as implementation guidance, troubleshooting, and comparative analysis. The Developer Knowledge MCP server can be connected to a user’s IDE or AI assistant. Google said the MCP server is compatible with a wide range of popular assistants and tools, helping to ensure that AI-based models have access to the most accurate, up-to-date information.

Full documentation can be found at developers.google.com. The preview focuses on providing high-quality, unstructured Markdown. As Google moves forward toward general availability, plans call for adding support for structured content such as specific code sample objects and API reference entities. In addition, the corpus will be expanded to include more of Google’s developer documentation and reduce re-indexing latency.
