MateClaw is a pluggable agent runtime that coordinates AI agents, tools, conversations, memory, and workflows. It is designed for personal and multi-user AI assistants, including agents used through chat platforms. Catalogue add-ons provide skills for extending its agent workflows.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00037 | $0.00695 |
| Opus 5.5 | $0.00015 | $0.00278 |
| Sonnet 5.5 | $0.00007 | $0.00139 |
| Haiku 4.5 | $0.00004 | $0.00069 |
Grade A, and why
browser_visible scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
浏览器启动模式
本技能控制 browser_use 的启动方式，核心参数：
| 参数 | 类型 | 说明 |
|---|---|---|
headed |
Boolean | true = 显示窗口；false（默认）= 无头模式 |
cdpPort |
Integer | 指定 CDP 调试端口（不填则自动选择） |
常见用法
无头模式（默认，后台自动化）
browser_use(action="start")
可见窗口（演示 / 需要人工操作）
browser_use(action="start", headed=true)
指定 CDP 端口（与外部工具共享）
browser_use(action="start", headed=true, cdpPort=9222)
标准操作序列
# 1. 启动
browser_use(action="start", headed=true)
# 2. 打开页面
browser_use(action="open", url="https://example.com")
# 3. 截取快照（查看页面内容）
browser_use(action="snapshot")
# 4. 点击元素
browser_use(action="click", selector="#submit-btn")
# 5. 输入文本
browser_use(action="type", selector="input[name=email]", text="[email protected]")
# 6. 完成后关闭
browser_use(action="stop")
何时用可见模式
| 场景 | 推荐参数 |
|---|---|
| 向用户演示操作过程 | headed=true |
| 需要用户手动登录（扫码、验证码） | headed=true，遇到登录页暂停并提示用户 |
| 调试自动化脚本 | headed=true |
| 纯自动化、不需要展示 | headed=false（默认） |
跨平台可执行文件路径（需自定义浏览器时）
MateClaw 的 browser_use 会自动检测系统浏览器，无需手动指定路径。如需调试特定 Chrome 安装位置：
Windows 默认路径：
C:\Program Files\Google\Chrome\Application\chrome.exe
C:\Program Files (x86)\Google\Chrome\Application\chrome.exe
macOS 默认路径：
/Applications/Google Chrome.app/Contents/MacOS/Google Chrome
Linux 默认路径：
/usr/bin/google-chrome
/usr/bin/chromium-browser
注意事项
- 可见模式需要图形环境（GUI）；无桌面的服务器无法使用
- 若浏览器已在运行，须先
stop再重新start才能切换headed状态 cdpPort被占用时会报错，换端口或先停止占用该端口的进程- 用户手动操作可见浏览器不会刷新 Agent 的 idle 超时计时
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 1mo ago First seen · 94 lines · 37 tokens per session scan A 95e548414360
browser_visible is a skill published in the GitHub repository mateaix/mateclaw (1,170 stars, last pushed yesterday), licensed Apache-2.0. It adds 37 tokens to every session and 695 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
