zerotoken-openclaw

zerotoken-openclaw is a skill for Claude Code, Codex from AMOS144/ZeroToken. It costs 36 tokens per session (4,882 once invoked), scanned A, original, MIT.

A workflow for using ZeroToken MCP through OpenClaw to automate browser tasks, record interaction paths, and replay them with fewer instructions. OpenClaw is a tool for running browser automation, while MCP is the connection used to access ZeroToken.

In plain words
What is it for?
Use it when a browser task must be recorded once and replayed later, especially for recurring automation; it is less suitable when every step needs human judgment.
Why use it?
It makes recurring or scheduled browser tasks easier to reuse and reduces the amount of repeated interaction needed.

Token cost

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.

Security

Grade A, and why

zerotoken-openclaw 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 9d 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.

ZeroToken 浏览器自动化(OpenClaw)

教会 Agent 使用 ZeroToken MCP 做浏览器自动化、轨迹录制与脚本重放。旨在让 OpenClaw 执行定时/重复任务时尽量少消耗 Token

ZeroToken 项目主页:https://github.com/AMOS144/zerotoken

何时使用 / 何时不该用

  • 适合使用
    • 需要通过 OpenClaw + ZeroToken MCP 做浏览器自动化,并且未来会 重复 / 定时执行 的任务。
    • 已经有一次完整的浏览器操作轨迹,希望将其 转成低 Token 消耗的脚本 来复用。
  • 不适合使用
    • 只想临时操作一次、没有复用需求的场景(直接用 ZeroToken MCP 即可)。
    • 页面强依赖人工决策,大量步骤都需要 fuzzy_point 介入、无人值守难以兜底的任务。

前置条件

  • 当前环境中已能通过 MCP 访问名为 zerotoken 的服务器(或等价的 MCP server id)。
  • 执行浏览器操作前需先调用 browser_init;完成后可选调用 browser_close

OpenClaw 使用前准备(HTTP 模式)

当通过 OpenClaw / MCPorter 使用 ZeroToken 时,因其每次调用会新建进程,导致 browser 状态丢失。需改用 Streamable HTTP 传输模式,服务常驻:

  1. 手动启动 HTTP 服务(在后台常驻):
    • zerotoken-mcp-http,或
    • zerotoken-mcp --transport streamable-http
    • 默认端口 8000,可用 --port 或环境变量 ZEROTOKEN_HTTP_PORT 覆盖。
  2. OpenClaw 配置:在 openclaw.jsonmcpServers.zerotoken 中,使用 URL 而非 command:
    {
      "mcpServers": {
        "zerotoken": {
          "url": "http://localhost:8000/mcp"
        }
      }
    }
    
    具体字段名以 OpenClaw 文档为准(可能为 streamable-httpurl)。

MCP 未配置 / 未安装 ZeroToken 时的处理

当调用 ZeroToken 相关 MCP 工具失败,并出现类似以下症状时:

  • 找不到名为 zerotoken 的 MCP server;
  • browser_init / trajectory_start 等工具报「tool not found」「MCP server unavailable」或 import 相关错误;

Agent 应按以下顺序处理:

  1. 明确告知用户:ZeroToken MCP 尚未在当前环境安装或启用,暂时无法使用浏览器自动化脚本能力。
  2. 询问用户当前所用平台(如「Cursor / OpenClaw / 其他支持 MCP 的客户端」),并指导用户安装 ZeroToken 及浏览器依赖:
    • OpenClaw + MCPortermcporter install zerotoken --target openclaw --configure重要:OpenClaw 需用 HTTP 模式,先在后台运行 zerotoken-mcp-http,再在 openclaw.json 中将 mcpServers.zerotoken 配置为 {"url": "http://localhost:8000/mcp"}(见上文「OpenClaw 使用前准备」)。
    • 如果平台有 MCP Marketplace / 插件市场
      提示用户在市场中搜索并启用 zerotoken MCP。
    • 如果是本地 Python 环境(如命令行 / 开发机)
      提示用户依次执行:
      1. 安装包:pip install zerotoken
      2. 安装 Playwright 浏览器依赖(否则浏览器工具会报错):
        • 普通环境:playwright install chromium
        • 如使用 uv:uv run playwright install chromium --with-deps
      3. 启动 MCP Server:OpenClaw 在后台运行 zerotoken-mcp-httpCursor 等 IDE 运行 zerotoken-mcp(或由客户端自动拉起)。
      4. 在客户端中,将该 MCP server 注册为 id 为 zerotoken 的 MCP;OpenClaw 需在 openclaw.json 中配置 URL(见「OpenClaw 使用前准备」)。
  3. 在用户确认 ZeroToken 已安装并启用后,Agent 再次从 browser_init 开始执行 ZeroToken 相关步骤。
