MCPSafari

Give Claude, Cursor, or any MCP-compatible AI full native control of Safari on macOS. Navigate tabs, click/type/fill forms (even React), read HTML/accessibility trees, execute JS, capture screenshots, inspect console & network — all with 24 secure tools. Zero Chrome overhead, Apple Silicon optimized, token-authenticated, and built with official Swift + Manifest V3 Safari Extension.

• Smarter element targeting (UID + CSS + text + coords + interactive ranking)
• Works flawlessly with complex sites
• Local & private (runs on your Mac)
• Perfect drop-in for Mac-first agent workflows

macOS 14+ • Safari 17+ • Xcode 16+

Built with the official swift-sdk and a Manifest V3 Safari Web Extension.

• 40–60% less CPU/heat on Apple Silicon
• Keeps your existing Safari logins/cookies
• Native accessibility tree (better than Playwright for complex UIs)

The MCP server communicates with clients over stdio and bridges tool calls to the Safari extension over a local WebSocket. The extension executes actions via browser APIs and content scripts injected into pages.
