Safari 27.0 Introduces MCP Server for AI Agent Control and Immersive Environment Support

Safari MCP Server for AI Agents

Safari 27.0 introduces the Safari MCP server, a new feature that enables AI agents to control the browser window. This functionality is designed to accelerate web development by allowing agents like Claude Code or Codex to interact directly with the browser, observing code rendering and verifying user states.

Developers can enable the Safari MCP server through Safari's Developer settings. The server operates locally, making no external network calls and not accessing personal information. It provides agents with access to the DOM, network requests, screenshots, and console output.

Expanded Capabilities for Developers

The MCP server allows AI agents to perform various tasks, including verifying user states in forms, comparing computed styles across browsers, testing accessibility issues, and analyzing performance metrics like navigation timing. This aims to reduce manual intervention and streamline debugging processes.

Apple has provided specific commands for connecting AI agents to Safari and is soliciting feedback and feature requests from developers regarding this new capability.

Immersive Environments and HTML <model> Element

Safari 27.0 also adds support for immersive environments, enabling developers to create these experiences within visionOS. This expands the scope of web content to new platforms.

Additionally, the HTML <model> element has been extended to iOS, iPadOS, and macOS. This allows websites to embed 3D models directly into web pages across Apple's mobile and desktop operating systems.

Bug Fixes and Stability Improvements

The update includes fixes for nearly 850 issues, significantly more than the 525 announced previously. These resolved issues span various areas, including accessibility, CSS, encoding, fonts, forms, MathML, networking, and WebRTC, contributing to overall browser stability and performance.
