Google has unveiled the public preview of its Developer Knowledge API and Model Context Protocol (MCP) server. These tools aim to provide AI-powered developer tools with access to the most up-to-date and accurate Google documentation. The API offers a programmatic source for Google's official documentation, allowing for search and retrieval of content in Markdown format.

This initiative addresses the growing need for AI tools to have reliable access to current information. By using the Developer Knowledge API, developers can avoid outdated data and web-scraping issues. The MCP server, an open standard, enables AI assistants to securely access external data sources. Connecting to the MCP server allows AI tools to “read” Google’s developer documentation.

With the API, developers can access documentation from various Google platforms and receive fresh content, with re-indexing within 24 hours. The API supports features such as comprehensive coverage, search, and retrieval. To get started, developers need to create an API key, enable the MCP server, and configure their tools. Google plans to add structured content in the future.

Ultimately, this release improves the quality of AI-assisted development workflows. The ability to retrieve and integrate documentation directly from Google will help developers build more reliable and accurate AI-powered tools. The move underscores Google's commitment to improving the development experience with AI.
