Saron Yitbarek, writing on the WebKit blog, with a nice post-WWDC surprise:
In Safari Technology Preview 247, we’re introducing the Safari MCP server — a Model Context Protocol server for web developers that makes your web development and debugging workflow faster and more powerful. We know agents are increasingly integral to the coding process and the Safari MCP server gives your agent the ability to know how your code actually renders in the browser by connecting it to a Safari browser window.
Any MCP-compatible client can connect to the Safari MCP server. By connecting your agent to a Safari browser window, your agent can emulate what your users experience, giving it the information it needs to debug more autonomously, like access to the DOM, network requests, screenshots, and console output.
MCP is Anthropic’s open protocol, so it was designed for Claude, but all sorts of other tools use it too — Gemini CLI, Cursor, GitHub Copilot, and more. MCP really is open, not “open”.
