cdp websocketmcp · stdiopython 3.12agent helpers
Connect an LLM directly to your real browser through one editable CDP websocket. The agent writes missing helpers as it works, so the harness improves with every task.
You will never use the browser again.Try browser-harness in/v4or paste the setup prompt into your coding agent.

Task:
“Open my X profile, find my latest 20 video posts, and download them.”
Setup prompt
Paste into Claude Code or Codex:
# setup prompt — Claude Code · Codex
$
Install or upgrade browser-harness to the latest stable version with uv using Python 3.12, register the skill from `browser-harness skill`, and connect it to my browser. Ask whether I want local browser recordings enabled; default to no and preserve my existing preference on upgrades. Follow https://github.com/browser-use/browser-harness/blob/main/install.md if setup or connection fails.
The agent will open chrome://inspect/#remote-debugging. On first setup, tick the checkbox so the agent can connect to your browser:
How it works
install.md — connects the agent to your browser.
SKILL.md — teaches it the browser workflow.
src/browser_harness/ — stays protected while the agent writes reusable helpers in its local workspace.
Scale with Browser Use Cloud
Use your local browser for logged-in, personal work. When you want many browsers in parallel — with live previews, proxies, stealth, CAPTCHA solving, and more — scale with /new-api-key.
/new-api-key
MCP server
browser-harness-mcp exposes the browser control helpers as MCP tools over stdio, so any MCP client (Claude Code, Devin, Cursor, etc.) can drive the browser without writing a second CDP layer. See docs/MCP.md for setup and client configuration.
