Google Stitch MCP API: Generate UI Designs via AI Agents
Google Labs Stitch now supports MCP servers, allowing AI tools like Claude Code and Cursor to generate UI designs through API calls. Note: Some details in this article are from unofficial sources and may change.

Google Stitch MCP API Released: AI Agents Can Now Directly Manipulate UI Designs
Note: This article is based on publicly available information and unofficial guides. Some details (free tier limits, tool names, model specifications) have not been officially verified by Google and may change. AI agents interact with Stitch via API calls, not direct GUI manipulation.
Google Labs' experimental AI UI design tool Stitch now officially supports MCP (Model Context Protocol) servers. You can now directly manipulate Stitch projects from AI coding tools like Cursor, Claude Code, and Gemini CLI.
