GoKawiilFollowing the rollout of Apple’s 2027 system releases, the WebKit blog has now published an in-depth look at what’s new with Safari 27.0. Here are the details.
Safari MCP server among new features
Chief among the new features included in Safari 27.0 is the Safari MCP server, which lets AI agents control the browser window to help developers work faster.
To enable Safari MCP, developers must go to Safari > Settings > Developer and check “Allow remote automation and external agents.” Apple notes that the Developer pane only appears after users enable “Show features for web developers” under Safari > Settings > Advanced.
Here’s Apple on the new feature:
Are you developing websites using coding agents? The Safari MCP server, now available in Safari 27.0 will make your workflow faster and more powerful. Give Claude Code, Codex, or the agent of your choice control over the browser window so it can see how your code renders. Safari MCP provides access to the DOM, network requests, screenshots, and console output. Your agent can do more on its own while you do less hopping between windows, less dropping screenshots in your terminal, and less typing prompts to describe what’s not working. The Safari MCP server enables your agent to: see how your code renders in Safari
verify user states in forms, checkout flows, selections & more
compare computed styles and layout to results in other browsers
test for accessibility issues like missing labels, improper ARIA attributes, and poor contrast
analyze performance with navigation timing and resource load times And much more. The MCP server runs entirely on your local machine. It makes no network calls of its own. It does not have access to your personal information in Safari. And any captured data goes directly to the agent you’re running, not to Apple.
