What its tools let an agent do: 9 read

Install Agent Browser in Claude Code, Cursor or VS Code

Runs npx -y aether-browser on your machine. Read the scan report first; the gateway never runs local packages.

What the publisher says

From the Agent Browser repository's README, as published. We do not edit it. Read it on GitHub

Agent Browser See what your agent sees.

Self-hosted Chrome for AI agents. Your agent drives one real browser session — and you can watch it happen, and step in.

Quickstart · API · MCP · Security model · Node client · Python client · Contributing · Changelog

An 18-second recorded demonstration. The agent signs in, reaches a 2FA prompt it has no way to answer, and stops. A human types the code into the displayed session, then the agent continues. Capture provenance, checksums, and independently verifiable limits are documented.  ·  How this was recorded

Why this exists

Most browser tooling for agents hands the model a browser you cannot see. When it misreads a page or stalls on a login, all you get is a transcript and a guess.

Agent Browser runs one headed Chrome session. Your agent drives it through a small JSON API, and a live view of that same session sits open in front of you. When the agent gets stuck, you take over in the window it is already using — then hand it back.

Start the runtime:

docker compose up --build

Then reach it however you like:

npm install aether-browser    # TypeScript
pip install aether-browser    # Python
claude mcp add agent-browser -- npx -y aether-browser mcp    # any MCP client

Quickstart

One command, on Docker Engine for Linux with Compose v2. It builds from the source checkout and starts Xvfb, x11vnc, noVNC, and the API — the stack that owns a single headed Chrome session. Both user-facing listeners bind to numeric loopback.

docker compose up --build

Once health responds, open the live view at 127.0.0.1:6080/vnc.html and check the API from another terminal:

curl -fsS http://127.0.0.1:8092/browser/health | jq .

Ctrl+C stops it.

The first build takes several minutes. It installs the hash-locked Python environment, then

uses Patchright to install the current Google Chrome Stable package. The exact browser version is

captured with each accepted image, so rebuilding the same source later may pick up a newer Stable.

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.
