Overview
bb-browser runs site adapters (one JS file per command) inside your real browser tab, using your existing cookies and login state. It ships 103 commands across 36 platforms, such as Twitter, Reddit, GitHub, arXiv and Zhihu, and also offers general automation (snapshot, click, fill, eval, network capture). Agents call it through a CLI or an MCP stdio server, and a local daemon talks to the browser over CDP.
Who it is for: Developers giving coding agents access to sites they are already logged into
Strengths
- Reuses your real logged-in browser, so no API keys or separate login flows
- Community adapters are single JS files in the bb-sites repo, in three auth tiers
- All commands support --json, --jq filtering and --tab for concurrent tabs
- Works as both CLI and MCP server for Claude Code, Cursor and similar agents
Weaknesses
- Adapters call undocumented site endpoints and page internals, so site changes can break them
- Acts with your personal accounts, so agent mistakes or prompt injection affect real logins
- Needs a running local daemon and your Chrome session, which is awkward for headless servers
- Daemon --host 0.0.0.0 option exposes browser control beyond localhost if misconfigured
What it needs
- no GPU
- Docker
- Needs Node.js 18+, Chrome (CDP) with bb-browser extension or daemon, OpenClaw (optional)
- port 19824
