Safari DevTools MCP server

Safari DevTools MCP

safari-devtools-mcp lets your coding agent (such as Claude, Cursor, Copilot or Gemini) control and inspect a live Safari browser on macOS. It acts as a Model-Context-Protocol (MCP) server, giving your AI coding assistant access to Safari DevTools for debugging, automation, and testing.

Chrome developers get powerful AI debugging through chrome-devtools-mcp by Google. Safari developers should have something equivalent — this project brings that same experience to Safari, with matching tool names and parameter schemas so you can swap between browsers with minimal friction.

Note: This server exposes browser content (page data, console logs, network traffic) to MCP clients. Avoid browsing sensitive websites or entering credentials while a session is active.

Why safari-devtools-mcp?

This project uses WebDriver for capabilities that scripting alone cannot provide:

• Network request/response body capture — intercepts fetch and XHR calls with full headers, payloads, and timing
• DOM snapshots via accessibility tree — stable element UIDs that survive page re-renders, not brittle CSS selectors
• CSS computed style inspection — read any computed property from any element
• Cookie and storage management — read, write, and delete cookies, localStorage, and sessionStorage
• Element-level screenshots — capture individual elements, not just the full viewport
• Session auto-recovery — detects dead SafariDriver sessions and reconnects transparently

Key features

• Browser debugging: Capture console logs, inspect network requests, and evaluate JavaScript — with stack traces and full request/response details.
• Reliable automation: Click, type, fill forms, drag and drop, and press keyboard shortcuts using accessibility-tree snapshots with stable UIDs.
• Native macOS integration: Tab management via AppleScript for listing, switching, and controlling Safari tabs across windows

Requirements

• macOS (Safari and SafariDriver are Apple-exclusive)
• Node.js 18+ (22+ recommended)
• Safari with remote automation enabled

Safari setup

1. Open Safari > Settings > Advanced > check "Show features for web developers"
2. Develop menu > check "Allow Remote Automation"
3. Authorize SafariDriver:

sudo safaridriver --enable
