 "title": "Run a web browsing agent in a local chat window",
 "page_title": "How to run a web browsing agent in a local chat window with Invisible Playwright MCP",
 "summary": "Start the standalone web UI with your OpenRouter key and type a browsing task on the left, watch the browser on the right.",
 "who": "A non-developer or someone without an MCP-capable assistant who wants to ask an agent to browse a site and see what it does.",
 "problem": "Most AI chat tools cannot open a live browser, so tasks that need real page interaction are left undone.",
 "outcome": "A local chat page at 127.0.0.1:8765 where the agent answers your request and the live browser is visible beside the chat.",
 "steps": [
  "Install uv with the README command for your system, for example `curl -LsSf https://astral.sh/uv/install.sh | sh` on Linux.",
  "Put your key in a file named .env in the folder you run from, as OPENROUTER_API_KEY=sk-or-..., so it stays out of your shell history.",
  "Run `uvx invisible-playwright-mcp ui` from that folder.",
  "Open http://127.0.0.1:8765 in your browser.",
  "Type a task such as checking a page for a specific piece of information, then read the answer and the live page side by side."
 ],
 "agent_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.",
 "agents": [
  "any"
 ],
 "difficulty": "Beginner",
 "time": "15 minutes",
 "basis": "readme",
 "caveat": "The web UI sends the conversation and what the agent reads on the page to OpenRouter under your key, so do not browse pages whose contents you would not share with that provider.",

 "tags": [
  "Work and operations"
 ],
 "lang": "python",
 "requirements": [
  "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",
  "Permission to automate the sites you point it at, and a read of their terms"
