ma-browser — your browser as the API, shared safely by many AI agents

Your browser is the API. No keys. No bots. No scrapers.

You're already logged into Twitter, Reddit, YouTube, Zhihu, Bilibili, LinkedIn, GitHub — ma-browser lets AI agents use that directly.

ma-browser site twitter/search "AI agent"       # search tweets
ma-browser site zhihu/hot                        # trending on Zhihu
ma-browser site arxiv/search "transformer"       # search papers
ma-browser site eastmoney/stock "茅台"            # real-time stock quote
ma-browser site boss/search "AI engineer"        # search jobs
ma-browser site wikipedia/summary "Python"       # Wikipedia summary
ma-browser site youtube/transcript VIDEO_ID      # full transcript
ma-browser site stackoverflow/search "async"     # search SO questions

103 commands across 36 platforms. All using your real browser's login state. Full list →

The idea

The internet was built for browsers. AI agents have been trying to access it through APIs — but 99% of websites don't offer one.

ma-browser flips this: instead of forcing websites to provide machine interfaces, let machines use the human interface directly. The adapter runs eval inside your browser tab, calls fetch() with your cookies, or invokes the page's own webpack modules. The website thinks it's you. Because it is you.

	Playwright / Selenium	Scraping libs	ma-browser
Browser	Headless, isolated	No browser	Your real Chrome
Login state	None, must re-login	Cookie extraction	Already there
Anti-bot	Detected easily	Cat-and-mouse	Invisible — it IS the user
Complex auth	Can't replicate	Reverse engineer	Page handles it itself

Quick Start

Install

npm install -g ma-browser

Use

ma-browser site update        # pull community adapters
ma-browser site recommend     # see which adapters match your browsing habits
ma-browser site zhihu/hot     # go

OpenClaw (no extension needed)

If you use OpenClaw, ma-browser runs directly through OpenClaw's built-in browser — no Chrome extension or daemon required:

ma-browser site reddit/hot --openclaw
ma-browser site xueqiu/hot-stock 5 --openclaw --jq '.items[] | {name, changePercent}'

10 minutes to add any website

ma-browser guide    # full tutorial

Tell your AI agent: "turn XX website into a CLI". It reads the guide, reverse-engineers the API with network --with-body, writes the adapter, tests it, and submits a PR. All autonomously.

Three tiers of adapter complexity:

Tier	Auth method	Example	Time
1	Cookie (fetch directly)	Reddit, GitHub, V2EX	~1 min
2	Bearer + CSRF token	Twitter, Zhihu	~3 min
3	Webpack injection / Pinia store	Twitter search, Xiaohongshu	~10 min

We tested this: 20 AI agents ran in parallel, each independently reverse-engineered a website and produced a working adapter. The marginal cost of adding a new website to the agent-accessible internet is approaching zero.

What this means for AI agents

Without ma-browser, an AI agent's world is: files + terminal + a few APIs with keys.

With ma-browser: files + terminal + the entire internet.

An agent can now, in under a minute:

# Cross-platform research on any topic
ma-browser site arxiv/search "retrieval augmented generation"
ma-browser site twitter/search "RAG"
ma-browser site github search rag-framework
ma-browser site stackoverflow/search "RAG implementation"
ma-browser site zhihu/search "RAG"
ma-browser site 36kr/newsflash

Six platforms, six dimensions, structured JSON. Faster and broader than any human researcher.

Also a full browser automation tool

ma-browser open https://example.com
ma-browser snapshot -i                # accessibility tree
ma-browser click @3                   # click element
ma-browser fill @5 "hello"            # fill input
ma-browser eval "document.title"      # run JS
ma-browser fetch URL --json           # authenticated fetch
ma-browser network requests --with-body --json  # capture traffic
ma-browser screenshot                 # take screenshot

All commands support --json output, --jq <expr> for inline filtering, and --tab <id> for concurrent multi-tab operations.

ma-browser site xueqiu/hot-stock 5 --jq '.items[] | {name, changePercent}'
# {"name":"云天化","changePercent":"2.08%"}
# {"name":"东芯股份","changePercent":"-7.60%"}

ma-browser site info xueqiu/stock   # view adapter args, example, domain

Daemon configuration

The daemon binds to 127.0.0.1:19824 by default. You can customize the host with --host:

ma-browser daemon --host 127.0.0.1    # IPv4 only (fix macOS IPv6 issues)
ma-browser daemon --host 0.0.0.0      # listen on all interfaces (for Tailscale / ZeroTier remote access)
