Two ways to use this browser agent
1. From your assistant, over MCP
Windows, in PowerShell:
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
$env:Path = "$env:USERPROFILE\.local\bin;$env:Path"
Linux:
curl -LsSf https://astral.sh/uv/install.sh | sh
source $HOME/.local/bin/env
Then install it in your assistant.
Claude Code:
claude plugin marketplace add feder-cr/invisible_playwright_mcp
claude plugin install invisible-playwright-mcp@feder-cr

Gemini CLI:

2. Standalone: the web UI
We bring the interface, you bring an OpenRouter key. Chat on the left, the live browser on the right.
Windows, in PowerShell:
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
$env:Path = "$env:USERPROFILE\.local\bin;$env:Path"
uvx invisible-playwright-mcp ui --openrouter-key sk-or-...
Linux:
curl -LsSf https://astral.sh/uv/install.sh | sh
source $HOME/.local/bin/env
uvx invisible-playwright-mcp ui --openrouter-key sk-or-...
Then open http://127.0.0.1:8765 and type the same thing.
