MCP Gateway

统一认证网关 —— 让 AI 快速接入企业内部系统。

通过一份 YAML 配置文件或运行时动态注册,自动将内部系统的 API 注册为 MCP (Model Context Protocol) Tools,统一处理 SSO / JWT / 用户名密码 / Playwright 交互式认证,AI 客户端(Claude Desktop、Cursor 等)即装即用。

特性

  • 配置驱动:新增系统只需编辑 systems.yaml,无需写代码
  • 无状态模式:不写配置文件也能用,AI 客户端通过 system_register 工具运行时动态注册系统
  • 四种认证:SSO (OAuth2 + PKCE)、JWT (自动刷新)、用户名密码 (Cookie 管理)、Playwright (浏览器交互式登录)
  • 自动重认证:Token 过期自动刷新,401/403 自动重新登录
  • Playwright 浏览器登录:无 OAuth2 clientId、验证码/2FA/滑块等复杂场景,打开浏览器手动登录后自动复用会话
  • SSO 浏览器登录:OAuth2 系统自动打开浏览器,登录后回调自动完成
  • TypeScript:完整类型支持,易于扩展

快速开始

安装

pnpm install
pnpm build

方式一:配置文件预加载(传统模式)

编辑 src/config/systems.yaml,按示例添加你的内部系统:

systems:
  - name: my-system
    description: 我的内部系统
    baseUrl: https://app.example.com
    auth:
      type: sso          # sso | jwt | basic | playwright
      sso:
        authorizeUrl: https://sso.example.com/oauth2/authorize
        tokenUrl: https://sso.example.com/oauth2/token
        clientId: your-client-id
        scope: user_id
        callbackPort: 9527
    tools:
      - name: get_data
        method: GET
        path: /api/data
        description: 获取数据

方式二:无状态动态注册(推荐)

不创建任何配置文件,直接启动 Gateway,由 AI 客户端通过 MCP 工具动态注册系统:

# 无需 systems.yaml,直接启动
node dist/index.js

AI 客户端连接后,调用 system_register 工具传入系统配置 JSON 即可动态注册,使用完毕后调用 system_remove 注销。

接入 AI 客户端

在 Claude Desktop 的 claude_desktop_config.json 或 Cursor 的 MCP 设置中添加:

{
  "mcpServers": {
    "gateway": {
      "command": "node",
      "args": ["/path/to/mcp-gateway/dist/index.js"]
    }
  }
}

开发模式

pnpm dev

指定配置文件

MCP_GATEWAY_CONFIG=/path/to/your/systems.yaml node dist/index.js

认证方式

SSO (OAuth2 Authorization Code + PKCE)

适用于接入企业 SSO 的系统。首次调用时自动打开浏览器完成登录,Token 自动缓存和刷新。

auth:
  type: sso
  sso:
    authorizeUrl: https://sso.example.com/oauth2/authorize
    tokenUrl: https://sso.example.com/oauth2/token
    loginPortal: https://sso.example.com/login    # 可选:统一登录门户
    clientId: your-client-id
    scope: user_id
    callbackPort: 9527

JWT

适用于有独立登录 API 的系统。支持自动 Token 刷新。

auth:
  type: jwt
  jwt:
    loginUrl: https://api.example.com/auth/login
    refreshUrl: https://api.example.com/auth/refresh
    tokenField: access_token
    refreshField: refresh_token
    expiresIn: 3600

用户名密码

适用于传统 Web 系统。自动管理 Cookie/Session。

auth:
  type: basic
  basic:
    loginUrl: https://erp.example.com/api/login
    cookieName: SESSION_ID

Playwright 交互式登录

适用于没有 OAuth2 clientId、或登录流程复杂(验证码/2FA/滑块)的系统。首次登录打开浏览器让用户手动操作,登录后自动保存会话并复用。

auth:
  type: playwright
  playwright:
    loginUrl: https://sso.example.com/login        # 登录页 URL(必填)
    successUrl: dashboard                           # 登录成功标志(必填)
    probeUrl: https://app.example.com/api/profile  # 会话探测 URL(可选)
    expiresIn: 1800000                             # 会话有效期(默认 30 分钟)
    channel: chrome                                 # 使用系统 Chrome(可选,避免下载 Chromium)
    # script: ./scripts/login.ts                    # 可选:录制脚本自动登录,失败降级交互式

浏览器引擎说明(无需手动安装):

  • 默认使用 Playwright 内置 Chromium,首次运行时自动下载(约 150MB)
  • channel: chrome 直接使用系统已安装的 Chrome,无需下载
  • channel: msedge 直接使用系统已安装的 Edge,无需下载
  • executablePath 指定浏览器路径(优先级最高)

内置管理 Tool

认证管理

Tool 说明
auth_status 查看所有系统的认证状态
auth_login 登录指定系统(SSO/Playwright 弹浏览器,JWT/Basic 传用户名密码)
auth_logout 登出指定系统或所有系统

系统管理(无状态模式)

Tool 说明
system_register 动态注册系统及 API 工具,传入系统配置 JSON
system_list 列出所有已注册系统的名称、类型、工具列表和认证状态
system_remove 注销指定系统,移除其所有工具和认证信息
