kimi-webbridge-mcp
MCP server that connects Kimi WebBridge to agents, enabling real-browser automation with ~28 wb_* tools while reusing your logged-in browser profile.
README
kimi-webbridge-mcp
把 Kimi WebBridge(daemon + 浏览器扩展)接到 Agent,采用与 Claude in Chrome 相同的架构分层(不是去接入 Claude 产品):
| 层 | 本仓库 | 作用 |
|---|---|---|
| Skill(薄) | skills/kimi-webbridge/SKILL.md |
何时用、工作流、禁止 curl |
| MCP | src/index.js |
真正执行:wb_* 工具 |
Grok Build(或其它 MCP 客户端)
├── Skill 路由 + 用法约定
└── MCP kimi-webbridge → :10086 daemon → 扩展 → 真实浏览器
- 真实浏览器 profile / 登录态(不导出 Cookie)
- 默认 compact ≈ 22 个工具(Claude-in-Chrome 体量,少而稳)
WEBBRIDGE_TOOL_PROFILE=full才开启 cdp / pdf / hover / fill_form 等扩展- 错误带
problem+hint;截图 jpeg 默认 quality 55 + 重试;click跟随 session 新标签;scroll支持 SPA/视频页
独立开源适配层,与 Moonshot / Kimi / xAI 无隶属关系。需自行安装官方 WebBridge。
前置条件
& "$env:USERPROFILE\.kimi-webbridge\bin\kimi-webbridge.exe" start
安装(MCP + Skill)
git clone https://github.com/Nimm0ny/kimi-webbridge-mcp.git
cd kimi-webbridge-mcp
npm install
npm run doctor
Grok Build
MCP — ~/.grok/config.toml(路径改成你的 clone):
[mcp_servers.kimi-webbridge]
command = "node"
args = ["D:\\path\\to\\kimi-webbridge-mcp\\src\\index.js"]
enabled = true
startup_timeout_sec = 15
tool_timeout_sec = 180
[mcp_servers.kimi-webbridge.env]
WEBBRIDGE_TOOL_PROFILE = "compact"
# Optional: only if sites open tabs outside the agent group
# WEBBRIDGE_CLICK_BORROW_ACTIVE = "1"
Skill(薄 playbook):
Copy-Item -Recurse -Force skills\kimi-webbridge "$env:USERPROFILE\.grok\skills\kimi-webbridge"
验证:
grok mcp doctor kimi-webbridge
# 或
npm run doctor
# wb_status 应显示 tool_profile=compact 与 tool_count≈22
工具摘要
Compact(默认)
wb_status · wb_navigate · wb_go_back · wb_go_forward · wb_reload · wb_list_tabs · wb_find_tab · wb_close_tab · wb_close_session · wb_snapshot · wb_get_text · wb_find · wb_wait · wb_click · wb_fill · wb_press_key · wb_scroll · wb_evaluate · wb_screenshot · wb_network · wb_console · wb_upload
Full only
wb_set_session · wb_dblclick · wb_hover · wb_fill_form · wb_cdp · wb_save_as_pdf
精确数量以 npm run smoke / wb_status.tool_count 为准(由 src/tool-profile.js 单一源计算)。

与 chrome-devtools-mcp
| 本项目 | chrome-devtools | |

| 浏览器 | 日常 profile | 常为独立实例 |
| 登录态 | 复用 | 另配 |
| 角色 | 真实站点操作 | 性能 / 干净环境 |
开发
npm start # MCP stdio (compact)
npm run doctor # daemon + extension + profile + tool count
npm run smoke # list-only compact tools
# full list-only:
# PowerShell: $env:WEBBRIDGE_TOOL_PROFILE='full'; npm run smoke
npm run smoke:e2e # browser smoke with full profile (dev clone)
安全
- 只连本机
:10086(非 localhost 的WEBBRIDGE_URL会被拒绝) - Agent 可操作已登录站点;勿在不受信任务中启用
- compact 含
wb_evaluate(页面 JS,可触及页面可见状态;勿用于窃取密钥) - full 含
wb_cdp:权限更大,仅在需要时开启 - 登录 / 验证码 / 扫码:在真实浏览器由用户完成,不要把密码写进对话
