Apple just made browser debugging significantly more interesting for AI coding agents. Safari Technology Preview 247, released July 1, 2026, ships a native Model Context Protocol (MCP) server built directly into Safari’s WebDriver binary. This means AI coding agents — Claude Code, Cursor, Gemini CLI, Codex, and others — can now inspect, interact with, and debug live websites running in Safari without any third-party tooling.

This guide walks through exactly how to set it up with Claude Code, including the prerequisites, configuration commands, and what you can actually do once it’s connected.

Accuracy note: All commands in this guide are sourced from the official Apple WebKit blog post at webkit.org/blog/18136/. Do not rely on guessed variations — use the exact paths and flags shown here.

What This Unlocks

Once connected, your Claude Code agent gains access to Safari-specific MCP tools including:

  • Navigation: navigate_to_url, list_tabs, switch_tab, close_tab
  • Page inspection: get_page_content, page_info, screenshot
  • JavaScript execution: evaluate_javascript, browser_console_messages
  • Network monitoring: list_network_requests, get_network_request
  • User interaction simulation: page_interactions (click, type, scroll, and more)
  • Accessibility and performance tools
  • Media emulation controls

This is a genuinely powerful debugging surface. An agent can see what a user sees in the browser, run JavaScript to inspect state, capture screenshots for visual verification, and monitor network traffic — all natively, with no additional proxy or browser extension required.

Prerequisites

Before you set anything up, you’ll need:

  1. Safari Technology Preview 247 or newer — download from the Apple Developer site (free with an Apple ID)
  2. Claude Code installed and configured on your Mac
  3. macOS (Safari Technology Preview is macOS-only)

Note: This uses Safari Technology Preview, not the release version of Safari. The MCP server is a developer feature and ships in the preview track first.

Step 1: Enable Developer Features in Safari Technology Preview

Open Safari Technology Preview, then:

  1. Go to Safari Technology Preview → Settings → Advanced
  2. Check “Show features for web developers”

After enabling that:

  1. Go to Safari Technology Preview → Settings → Developer
  2. Enable “Enable remote automation and external agents”

Without this setting enabled, the MCP server won’t start when called by an external agent.

Step 2: Add the MCP Server to Claude Code

Run this command in your terminal:

claude mcp add safari-mcp-stp -- "/Applications/Safari Technology Preview.app/Contents/MacOS/safaridriver" --mcp

This registers the Safari MCP server with Claude Code using the safaridriver binary (Safari’s built-in WebDriver executable) with the --mcp flag, which activates the MCP server mode.

The server runs locally and communicates over standard MCP transport. No network ports are opened; no external services are involved.

Step 3: Verify the Connection

Once added, you can verify the server appears in Claude Code’s MCP configuration:

claude mcp list

You should see safari-mcp-stp listed as an available server. If it appears, the setup is complete.

Alternative: JSON Configuration for Other MCP Clients

If you’re using Cursor, Gemini CLI, or another MCP-compatible agent, you can add the server via JSON configuration (typically in mcp.json or your agent’s config file):

{
  "mcpServers": {
    "safari-mcp-stp": {
      "command": "/Applications/Safari Technology Preview.app/Contents/MacOS/safaridriver",
      "args": ["--mcp"]
    }
  }
}

For Codex specifically, the CLI command is:

codex mcp add safari-mcp-stp -- "/Applications/Safari Technology Preview.app/Contents/MacOS/safaridriver" --mcp

What a Real Debugging Session Looks Like

Once connected, your agent can work alongside a live browser session. A typical flow might look like:

  1. You open a webpage in Safari Technology Preview
  2. You describe a UI bug or rendering issue to Claude Code
  3. Claude Code uses screenshot to see the current state, get_page_content to read the DOM, and browser_console_messages to check for JavaScript errors
  4. It proposes a fix, uses evaluate_javascript to test it in-place, then captures another screenshot to verify

The key difference from other browser automation approaches is that Safari Technology Preview is your actual browser. The agent isn’t running a headless Chrome instance — it’s seeing what you’d see if you opened the page yourself.

A Note on Scope

This guide covers setting up the connection with Claude Code. The full range of available MCP tools and their parameters is documented in the official WebKit blog post. If you run into discrepancies between what’s described here and what’s in the current version of Safari Technology Preview, the official WebKit documentation is the authoritative source — not this article.

The Safari MCP server is the first browser-native MCP integration from a major browser vendor. Expect the tool surface to expand in future Technology Preview releases.
