## โŒ Without Safari MCP Your AI agent needs to browse. So it either: - **Spins up Chromium via Playwright** โ€” with no logins, no cookies, no sessions - **Uses Chrome DevTools MCP** โ€” and melts your fan running a second browser - **Relies on headless scrapers** โ€” blocked by Cloudflare, reCAPTCHA, and bot detection ## โœ… With Safari MCP Your AI drives the **Safari you're already logged into** โ€” Gmail, GitHub, Ahrefs, Slack, banking. Native WebKit. ~60% less CPU. Background operation. 97 tools. One `npx` command. macOS only. > ๐Ÿ“ฐ **Featured on freeCodeCamp:** [How to Connect Your AI Coding Agent to a Browser on macOS](https://www.freecodecamp.org/news/how-to-connect-your-ai-coding-agent-to-a-browser-on-macos/) ยท [HackerNoon: Reverse-Engineering React, Shadow DOM, and CSP](https://hackernoon.com/i-had-to-reverse-engineer-react-shadow-dom-and-csp-to-automate-safari-without-chrome) > ๐ŸŽ **Apple shipped an official Safari MCP** (July 2026 โ€” Safari Technology Preview 247+ and the Safari 27 beta). It's built on `safaridriver` for isolated debugging sessions. safari-mcp drives the **real Safari you're already logged into** โ€” on the stable Safari that ships with macOS today, with 97 tools. See the full comparison below. --- ## Highlights - **97 tools** โ€” navigation, clicks, forms, screenshots, network, storage, accessibility, and more - **Zero heat** โ€” native WebKit on Apple Silicon, ~60% less CPU than Chrome - **Your real browser** โ€” keeps all logins, cookies, sessions (Gmail, GitHub, Ahrefs, etc.) - **Background operation** โ€” Safari stays in the background, no window stealing - **No browser dependencies** โ€” no Puppeteer, no Playwright, no WebDriver, no Chrome - **Persistent process** โ€” reuses a single osascript process (~5ms per command vs ~80ms) - **Framework-compatible** โ€” React, Vue, Angular, Svelte form filling via native setters --- ## In users' own words Not solicited testimonials โ€” quotes lifted from the public issue tracker, each linked to the thread it came from. > "I run multiple Pi sessions/subagents against my normal Safari profile in parallel. **Sharing its cookies and logins is intentional.**" > โ€” [@maxim](https://github.com/achiya-automation/safari-mcp/issues/76), on running concurrent agents against a real browser > "The server has a deliberate tab-ownership model โ€ฆ **the code is careful about this, and for the default case that's the right safety posture.**" > โ€” [@turner-moore](https://github.com/achiya-automation/safari-mcp/issues/92), on why the guards refuse to touch your tabs > "Direct local validation from the package: **Safari MCP doctor 6/6.**" > โ€” [@jrepp](https://github.com/achiya-automation/safari-mcp/pull/53), who found and fixed a queue-alignment bug in the focus helper --- ## Quick Start ### Prerequisites - macOS (any version with Safari) - Node.js 20+ - Safari โ†’ Settings โ†’ Advanced โ†’ **Show features for web developers** โœ“ - Safari โ†’ Develop โ†’ **Allow JavaScript from Apple Events** โœ“ ### Install (one command) ```bash npx safari-mcp ``` That's it โ€” no global install needed.

--- ## Usage Workflow The recommended pattern for AI agents using Safari MCP: ``` 1. safari_snapshot โ†’ Get page state (accessibility tree) 2. safari_click/fill/... โ†’ Interact with elements by ref 3. safari_snapshot โ†’ Verify the result ``` **Element targeting** โ€” tools accept multiple targeting strategies: | Strategy | Example | Best for | |----------|---------|----------| | CSS selector | `#login-btn`, `.submit` | Unique elements | | Visible text | `"Sign In"`, `"Submit"` | Buttons, links | | Coordinates | `x: 100, y: 200` | Canvas, custom widgets | | Ref from snapshot | `ref: "e42"` | Any element from accessibility tree | > **Tip:** Start with `safari_snapshot` to get element refs, then use refs for precise targeting. This is faster and more reliable than CSS selectors. --- ## Running several agents at once Multiple agents or subagents driving one Safari at the same time will fight over the active tab โ€” unless you run them against a **shared HTTP daemon** instead of one process per client: ```bash SAFARI_MCP_HTTP=1 SAFARI_MCP_HTTP_PORT=9225 npx safari-mcp ``` Then point every client at it: ```json { "mcpServers": { "safari-mcp": { "type": "http", "url": "http://127.0.0.1:9225/mcp" } } } ``` One daemon, many sessions โ€” and each session gets its **own tab state**. The server keys `activeTabIndex`, the ownership flag and a unique tab marker off the MCP session id, so session A physically cannot read or steer session B's tab. Two properties make this safe rather than merely tidy: - **Tab identity is a marker, not an index.** Each session stamps a unique id into the page it opens, so ownership survives navigation *and* survives the user reordering or closing other tabs. An index alone would silently drift onto the wrong tab. - **It fails closed.** If a session's marked tab can't be re-found, every tool refuses instead of falling back to whatever tab is in front โ€” because that tab is usually yours: ``` Tab tracking lost โ€” refusing to fall back to "current tab of window" (would target the user's active tab). Call safari_new_tab to reopen. ``` This also drops process count sharply: ~17 node processes for 17 concurrent sessions becomes 1. `SAFARI_PROFILE` stays optional โ€” leave it unset and sessions bind to your ordinary Safari windows, cookies and logins intact. Details in [docs/http-transport-design.md](docs/http-transport-design.md). Prefer stdio (one process per agent) over a persistent daemon? That works too โ€” isolation then comes from the process boundary itself. One caveat: if your client multiplexes agents through [mcporter](https://github.com/openclaw/mcporter), mcporter caches a single MCP client for all of them โ€” whichever transport you pick โ€” so the server never sees distinct sessions and per-session isolation can't engage. [mcporter-lanes](https://pi.dev/packages/mcporter-lanes) (a pi extension by [@maxim](https://github.com/maxim), born out of [#76](https://github.com/achiya-automation/safari-mcp/issues/76)) fixes this upstream: each agent session gets its own daemon dir โ€” and therefore its own safari-mcp โ€” with an idle timeout so processes don't pile up. --- ## Environment variables | Variable | Default | What it does | |----------|---------|--------------| | `SAFARI_MCP_HTTP` | off | Run one shared HTTP daemon instead of a process per client (see above). | | `SAFARI_MCP_HTTP_PORT` | `9225` | Port for that daemon. | | `SAFARI_PROFILE` | unset | Bind sessions to a named Safari profile. Unset = your ordinary windows. | | `SAFARI_MCP_RAISE_ON_NAVIGATE` | off | Let navigation bring Safari to the front, and stop the focus guard from putting your previous app back. | `SAFARI_MCP_RAISE_ON_NAVIGATE=1` is for agents whose whole point is *showing* you a page โ€” a voice assistant answering "open YouTube", a demo driver. Everything else should leave it off: by default Safari MCP works in the background and hands focus back to whatever app you were using, so an agent can drive a page while you keep typing somewhere else. --- ## Tools (97)

That's great validation for the category โ€” and it's built for a different job. Apple's server drives an **isolated WebDriver automation session** for debugging; safari-mcp drives the **real Safari you're already logged into**. It has not reached a stable Safari release yet: on macOS 26.5.2 with Safari 26.5.2, `safaridriver --help` lists `--port`, `--bidi`, `--enable` and `--diagnose`, and no `--mcp` (verified 2026-07-23). Check your own machine with `safaridriver --help | grep mcp` before assuming either way. | | ๐Ÿฆ safari-mcp *(this repo)* | Apple `safaridriver --mcp` | |---|:---:|:---:| | **Your real logins / cookies** | โœ… Your actual Safari | โš ๏ธ Isolated automation session โ€” no access to AutoFill or browsing activity | | **Runs on** | โœ… Stable Safari, every Mac | โš ๏ธ Safari Technology Preview 247+ or the Safari 27 beta โ€” not in stable Safari 26.5 | | **Background (no focus steal)** | โœ… Yes | โŒ Dedicated window with a "controlled by automation" banner | | **Tools** | **97** | ~17 | | **Storage** (cookies, localStorage, IndexedDB) | โœ… 10 tools | โŒ | | **Network mocking + throttling** | โœ… Yes | โŒ Read-only network inspection | | **Device emulation** (iPhone, iPad) | โœ… Yes | โš ๏ธ Viewport + media type only | | **Setup** | `npx safari-mcp` | Enable "remote automation and external agents", then point your client at that build's `safaridriver --mcp` | | **Official Apple support** | โŒ Community (MIT) | โœ… Apple, WebDriver-standard | > **When Apple's server is the right pick:** you specifically want a clean-room, WebDriver-standard session for compatibility debugging and you already run a preview or beta build. **For everything else โ€” daily automation on the browser you're already signed into, on the Safari that shipped with your Mac โ€” safari-mcp is built for exactly that.** ### Why Safari MCP and Not the Other Safari MCP Projects?

Without it, ~80% of functionality works via AppleScript alone. The extension adds capabilities that AppleScript cannot provide: ### What the Extension Adds | Capability | With Extension | AppleScript Only | |-----------|:--------------:|:----------------:| | Closed Shadow DOM (Reddit, Web Components) | โœ… Full access | โŒ Invisible | | Strict CSP sites | โœ… Bypasses via MAIN world | โŒ Often blocked | | React/Vue/Angular state manipulation | โœ… Deep (Fiber, ProseMirror) | โš ๏ธ Basic | | Loading state detection (spinners, skeletons) | โœ… Smart detection | โŒ No | | Dialog handling (alert/confirm) | โŒ | โœ… Only AppleScript | | Native OS-level click (CGEvent) | โŒ | โœ… Only AppleScript | | PDF export | โŒ | โœ… Only AppleScript | > **When do you need the extension?** If you're automating modern SPAs with closed shadow DOM (e.g., Reddit), sites with strict Content Security Policy, or framework-heavy editors (Draft.js, ProseMirror, Slate). ### Installing the Extension The extension requires a one-time build with Xcode (free, included with macOS). > **Note for npm users:** The `xcode/` directory is not included in the npm package. > Clone the [GitHub repository](https://github.com/achiya-automation/safari-mcp) to build from source. **Prerequisites:** Xcode (install from App Store โ€” free) ```bash # 1.

Open the app (needed once so Safari registers the extension) open "$APP_PATH" ``` > **Do not ad-hoc re-sign `Safari MCP.app` with `codesign --deep --sign -`.** That replaces the Apple Development identity on the wrapper and embedded extension; current Safari can then silently disable or mark the extension as removed. If a previous build was ad-hoc signed, run the `clean build` command above again. Alternatively, open `xcode/Safari MCP/Safari MCP.xcodeproj` directly in Xcode, select your Apple ID under Signing & Capabilities, and click Run. A free personal Apple Developer account is sufficient for local use. Then in Safari: 1. Safari โ†’ Settings โ†’ Advanced โ†’ enable **Show features for web developers** 2. Safari โ†’ Develop โ†’ **Allow Unsigned Extensions** (required each Safari restart) 3. Safari โ†’ Settings โ†’ Extensions โ†’ enable **Safari MCP Bridge** The extension connects automatically to the first local bridge whose declared Safari profile matches its own. The default bridge ports are `9224`, `9228`, `9232`, and `9236`; a single-profile setup normally uses `9224`. > **Note:** "Allow Unsigned Extensions" resets every time Safari restarts. You'll need to re-enable it in the Develop menu after each restart. The extension itself stays installed. **Toolbar icon status:** - **ON** โ€” connected to MCP server - **OFF** โ€” manually disabled via popup - *(no badge)* โ€” server not running, will auto-reconnect --- ## macOS Permissions Safari MCP needs these one-time permissions: | Permission | Where | Why | |-----------|-------|-----| | JavaScript from Apple Events | Safari โ†’ Develop menu | Required for `do JavaScript` | | Automation โ†’ Safari | System Settings โ†’ Privacy & Security โ†’ Automation | Required for all AppleScript-backed tools | | Screen Recording | System Settings โ†’ Privacy & Security โ†’ Screen Recording | Required for `safari_screenshot` | | Accessibility (safari-helper) | System Settings โ†’ Privacy & Security โ†’ Accessibility | Required for `safari_native_click`, `safari_native_keyboard`, `safari_native_hover` and `safari_save_pdf` | ### Granting Accessibility to safari-helper (required for `safari_native_*`) The `safari_native_click`, `safari_native_keyboard` and `safari_native_hover` tools inject OS-level `CGEvent` events into Safari without stealing focus. macOS requires the underlying helper binary to be approved in **Accessibility** before those events can reach a non-frontmost window. 1. Open **System Settings โ†’ Privacy & Security โ†’ Accessibility**. 2. Click `+` (unlock with your password if needed). 3. Navigate to the helper binary and add it: - npm global install: `$(npm root -g)/safari-mcp/safari-helper` - npx / project install: `./node_modules/safari-mcp/safari-helper` - From source clone: `/path/to/safari-mcp/safari-helper` 4. Make sure the toggle next to it is **ON**. The postinstall script re-signs the helper with a stable identifier (`com.achiya-automation.safari-mcp`) so this permission survives future upgrades โ€” without that step, every `npm update` would silently revoke approval because the binary's adhoc-signed identifier changes per build. If `safari_native_click` reports success but the page doesn't react (no `isTrusted: true` click events fire), the helper is most likely missing this approval. The `safari_*` (non-`native_`) tools don't need it. ### Granting Automation โ†’ Safari (important for IDE users) macOS TCC grants Automation permission to the **parent process** that spawns the MCP server, not to `safari-mcp` itself. So you need to grant **Automation โ†’ Safari** to the app that runs Claude Code / Cursor / Windsurf โ€” typically **Visual Studio Code** or **Terminal**. If the permission dialog never appears automatically, run this command once from a Terminal that already has Automation permission: ```bash osascript -e 'tell application "Safari" to get URL of current tab of window 1' ``` That call registers the Terminal app in the Automation database and then triggers the prompt for Safari. After you approve it, subsequent MCP calls from any child process chain will work. --- ## Troubleshooting | Issue | Fix | |-------|-----| | "AppleScript error" | Enable "Allow JavaScript from Apple Events" in Safari โ†’ Develop | | "Not authorized to send Apple events to Safari" | Grant Automation โ†’ Safari to your IDE (see above) | | "Not authorized" after `npm update` | Updating changes the binary's cdhash โ€” macOS silently revokes Automation permission. Re-run the `osascript` one-liner above to re-grant it | | `safari_native_click` reports success but page doesn't react | Add `safari-helper` to **System Settings โ†’ Privacy & Security โ†’ Accessibility** (see [Granting Accessibility](#granting-accessibility-to-safari-helper-required-for-safari_native_) above). Confirm by attaching a `click` listener with `{capture:true}` in the page console โ€” without the grant, no `isTrusted: true` event fires | | Screenshots empty | Grant Screen Recording permission to Terminal/VS Code | | Tab not found | Call `safari_list_tabs` to refresh tab indices | | Hebrew keyboard issues | All typing uses JS events โ€” immune to keyboard layout | | HTTPS blocked | `safari_navigate` auto-tries HTTPS first, falls back to HTTP | | Safari steals focus | Ensure you're on latest version โ€” `newTab` restores your active tab | --- ## Works With Safari MCP works with any MCP-compatible client: | Client | Status | |--------|--------| | [Claude Code](https://claude.ai/claude-code) | โœ… Tested daily | | [Claude Desktop](https://claude.ai/download) | โœ… Tested | | [Cursor](https://cursor.sh) | โœ… Tested | | [Windsurf](https://codeium.com/windsurf) | โœ… Compatible | | [VS Code + Continue](https://continue.dev) | โœ… Compatible | --- ## Contributing PRs welcome!
