setup skillB
This file is byte-identical to the first copy the registry indexed. Same content hash, same audit grade.
setup is agent-read markdown (skill) from feder-cr/invisible_playwright_mcp: What the invisible_playwright_mcp browser server needs on this machine - the patched Firefox it drives, which the server downloads on its own the first time it runs. Use when browser_open answers that the engine is downloading or that its download failed, or right after installing the plugin..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
The server runs with `uvx invisible-playwright-mcp` and needs its browser engine on this machine once, about a quarter of a gigabyte. It downloads it on its own when it starts; while that is in flight, `browser_open` answers with how far the download is instead of opening a browser, and asking again a minute later is all that is needed. To do the download ahead of time, or again after it failed, in a terminal where the user can watch it, run the block for the user's system: Windows, in PowerShell: ```powershell powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex" $env:Path = "$env:USERPROFILE\.local\bin;$env:Path" uvx invisible-playwright fetch ``` Linux: ```bash curl -LsSf https://astral.sh/uv/install.sh | sh source $HOME/.local/bin/env uvx invisible-playwright fetch ``` Nothing else to configure: no account, no key. Over MCP the model is the client's own.

How to install
mdr add feder-cr/invisible_playwright_mcp/setup@git:20260923.a602cffmdr add feder-cr/invisible_playwright_mcp/setup@sha256:6a232539eb2f00afPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
