Library

Browser Use

Open-source browser agent library that runs locally with any LLM; a paid cloud adds hosted browsers.

Why it is useful

Use it when a task needs a full agent loop over web pages rather than single commands.

CLI for agents
agent-browser
Native Rust CLI that gives an agent a persistent browser: snapshot returns the page as compact text with element refs, and the agent acts on refs one command at a time.
MCP server
Chrome DevTools MCP
Lets a coding agent control and inspect a live Chrome through DevTools, as an MCP server or a CLI, for automation, debugging and performance traces.
Agent SDK
Claude Agent SDK for Python
Python SDK that exposes Claude Code's agent loop, tools, hooks and MCP support so you can build your own agents in Python 3.10+.
Skill
ego lite (ego-browser skill)
The ego-browser agent skill and its open-source Node.js CDP harness for the ego lite browser: the agent runs ego-browser skill for a version-matched guide, then sends JavaScript that calls snapshot, fill, click, wait, navigate and capture inside its own isolated Space.
Skill pack
gstack
Garry Tan's skill pack that turns Claude Code and other agents into a virtual engineering team: office hours, CEO and eng plan reviews, design review, code review, QA with a real browser, security audit and ship.
MCP server
LinkedIn MCP Server
Python MCP server that drives LinkedIn through the user's own browser session with Patchright: tools read profiles, companies, employees, jobs, the feed, posts and the inbox, and a smaller set sends messages, connection requests and job dismissals.
