4 use cases

  • Compare flight fares across a date range from your assistant

    Have your assistant check each date in a range on a booking site and report the cheapest fare per day.

    View prompt
    Using the invisible_playwright_mcp server from feder-cr/invisible_playwright_mcp, open <booking-site-url> and check the cheapest economy fare for one adult, one checked bag, from <origin> to <destination>, for each date from <start-date> to <end-date>, clicking the days in the calendar widget one at a time. Expected output: one line per date with the cheapest fare or the words no availability. Verify that no booking was submitted.

  • Run a web browsing agent in a local chat window

    Start the standalone web UI with your OpenRouter key and type a browsing task on the left, watch the browser on the right.

    View prompt
    Using the invisible-playwright-mcp web UI from feder-cr/invisible_playwright_mcp, send this task to the agent: <task describing the page and the information wanted at <target-url>>. Expected output: the agent's answer in the chat, with the browser showing the page it read. Verify that the answer names the source page and does not guess any value the page did not show.

  • Keep logins and cookies between agent browsing runs

    Store the browser profile in a folder so the agent stays signed in to sites after a restart.

    View prompt
    Using the invisible-playwright-mcp server from feder-cr/invisible_playwright_mcp with a profile directory set to <profile-folder>, open <site-url> and report whether the account page loads without a login prompt. Expected output: a yes or no with the page title. Verify that the profile folder now contains the session data after the first run.

  • Write Python browser scripts on the engine library

    Use the invisible_playwright engine from Python code, with Playwright's API, instead of prompts.

    View prompt
    Using the invisible_playwright library from feder-cr/invisible_playwright, write a Python script that opens <target-url>, reads <element-or-field>, and prints the value. Expected output: the printed value and the URL it came from. Verify that the script stops with an error, not a guessed value, when the element is missing.

How to use Invisible Playwright MCP

  1. Check you have what it needs: uv installed, using the install command for your operating system from the README; An OpenRouter API key for the standalone web UI and for model calls; An MCP-capable assistant such as Claude Code, Codex or Gemini CLI, for the MCP route.
  2. Open feder-cr/invisible_playwright_mcp on GitHub and read the README and license.
  3. Install uv for your system with the README command: curl -LsSf https://astral.sh/uv/install.sh | sh on Linux, or the PowerShell command on Windows.
  4. Run claude plugin marketplace add feder-cr/invisible_playwright_mcp and then claude plugin install invisible-playwright-mcp@feder-cr in Claude Code.
  5. Or, in Codex, run codex plugin marketplace add feder-cr/invisible_playwright_mcp and then codex plugin add invisible-playwright-mcp@feder-cr.
  6. Give the assistant your route, passengers, cabin and date range, and ask it to click each day in the calendar widget rather than typing dates.

These steps come from our top use case, Compare flight fares across a date range from your assistant, which also has a copy-paste agent prompt.
