Two ways to use this browser agent
1. From your assistant, over MCP
Windows, in PowerShell:
Linux:
Then install it in your assistant.
**Claude Code:**
**Codex:**
**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:
Linux:
Then open **http://127.0.0.1:8765** and type the same thing.

What to ask a web browsing agent
Anything that needs real web automation: a browser rather than an API, and a
person's judgement about what is on the page.
> Go to . 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.
It drives the page the way a person would: the pointer moves, keys are pressed.
Options: proxy, profile, seed
- **--openrouter-key** Your key, or the OPENROUTER_API_KEY variable.
- **--model** An OpenRouter model id, or INVISIBLE_MCP_MODEL. Defaults to z-ai/glm-5.3-flash.
- **--proxy** Optional. http://user:pass@proxy.example.com:8080 or
socks5://proxy.example.com:1080. Host and port are both required. The
timezone, locale and egress follow it.
- **--binary** An engine binary you already have. It must be the build the seal
pins, or startup refuses: this skips the download, not the version check.
- **--seed** An integer. Same seed, same browser identity, every run.
- **--profile-dir** A directory to keep the profile in, so logins and cookies
survive restarts.
- **--headed** Show the browser window. The interface shows you the page anyway.
- **--host, --port** 127.0.0.1 and 8765. Changing the host
exposes an interface that has no authentication.
A .env beside the command
Rather than retyping the key and the binary path, put them in a .env in the
directory you run from:
It is read at startup, and on the way in it **never overrides** something
already set, so the order is --flag > the environment > .env > the default.
Only the directory you are in is read - there is no search upwards, so running
from a subfolder cannot silently pick up a different key. The startup line names
the variables it applied and never prints their values.
Passing --openrouter-key puts the key in your shell history, and on Linux in
the process list. OPENROUTER_API_KEY in the environment or in a .env avoids
both.
The wiki: AI browser-agent guides
The reading room around the agent lives in the
wiki: the
AI browser-agent landscape: browser-use, Operator-style and
computer-use agents compared,
what to check when an agent gets blocked,
and what happened to OpenAI Operator,
among others. Worked examples, transcripts and their outputs live in

The rest of the family: engine, core
The MCP server from option 1 ships inside this package: invisible_playwright_mcp with no
