Born as an AI web agent that applied to jobs in bulk. Becoming a general one: an agent you point at the web and tell what to do.

Overview

AIHawk gives your AI client a real browser and lets you drive it in plain language. Open pages, read them, click, type, come back with the answer.

It installs as a package, invisible-playwright-mcp, and connects over MCP, the protocol AI clients use to attach external tools. Your client gets thirteen tools; you never call them yourself.

Requirements

Python 3.11 or newer, Windows or Linux, and uv, which provides the uvx command.

curl -LsSf https://astral.sh/uv/install.sh | sh              # macOS, Linux
powershell -c "irm https://astral.sh/uv/install.ps1 | iex"   # Windows

If you use Claude Code, Claude Desktop, Cursor or anything similar, you already have the client half.

Installation

claude mcp add stealth --env STEALTHFOX_PROXY=http://user:pass@host:port -- uvx invisible-playwright-mcp

Drop the --env flag if you are not using a proxy. In any other client, the same thing as a config entry:

{
  "mcpServers": {
    "stealth": {
      "command": "uvx",
      "args": ["invisible-playwright-mcp"],
      "env": {
        "STEALTHFOX_PROXY": "http://user:pass@host:port",
        "STEALTHFOX_SEED": "12345",
        "STEALTHFOX_PROFILE_DIR": "/absolute/path/to/profile"
      }
    }
  }
}

Usage

Restart the client and list your MCP servers. stealth should be there with thirteen tools attached. Ask for one small thing first, like opening a page and taking a screenshot.

The first launch downloads a few hundred megabytes and looks like a hang. It is cached after that. If the server never appears at all, uvx is not on the PATH your client sees, which is not always the PATH your shell sees.

The server drives the browser and nothing else: it has no disk access. Reading and writing files is your client's own tooling.

Two things worth asking it:

Go to <paste the URL>. Filter to backend roles in Europe posted in the last two weeks. For each result, open the posting and pull out the title, the location, whether it says remote or hybrid, and anything about visa sponsorship. Give me the list as a table, and append a row to shortlist.csv for each one.

Go to <paste the URL>. One way, Milan to Lisbon, economy, one checked bag, one adult. Check every date from the 12th to the 16th of next month, one at a time, and read the cheapest fare for each day. The date field is a calendar widget, so click the days rather than typing them. If a date has no availability say so, do not guess a number. Write the five to flights.md sorted by price, and leave the cheapest open in a tab.

Those two share nothing but the machinery.

Configuration

Environment variables on the MCP server entry.

| Variable | What it does | |---|---| | STEALTHFOX_PROXY | http://user:pass@host:port, or socks5://. Credentials go in the URL. | | STEALTHFOX_SEED | An integer. Same seed, same browser identity, every run. Set one for anything you run more than once. | | STEALTHFOX_PROFILE_DIR | Absolute path. Persistent profile, so logins and cookies survive restarts. Most clients pass env values through verbatim, so a leading ~ becomes a folder literally named ~. | | STEALTHFOX_HEADLESS | Headless by default. Set 0 to watch the window, worth doing the first few times. |

Available tools

You never call these yourself. Your model does, from what you ask it.

| Group | Tools | |---|---| | Pages | session_new_page, session_list_pages, session_select_page, session_close_page | | Reading | browser_navigate, browser_read_text, browser_snapshot, browser_take_screenshot | | Acting | browser_click, browser_click_at, browser_type, browser_press_key, browser_evaluate |

Related projects

| Project | What it is | |---|---| | invisible-playwright-mcp | The MCP server installed above. | | invisible_playwright | The Python wrapper and the browser it pins and drives. Use it directly if you would rather script than prompt: the API is Playwright's. | | invisible_core | Seed to fingerprint to preferences, proxy and geolocation derivation. |

Issues and pull requests are welcome on whichever of those the problem lives in. If you are not sure, open it here.

When something fails on a page, say which step, what the page did, what the tool returned and which exit country you were on. "It got blocked" is not something anyone can act on.

This automates a browser under your control. Read the terms of the sites you point it at, respect their rate limits, and do not submit anything a human has not read.
