HallucC MCP Server

English | 在线体验 | 官方 MCP Registry | 魔搭 MCP 广场 | Coze 商店

给 AI 装上「事实核验 + 安全网关」:逐声明幻觉检测、Agent 轨迹六维评估、CUA 动作 L0-L3 风险分级、40+ 特征注入/越狱拦截——一个 MCP server,四个工具,接入 Claude Code / Cursor / Claude Desktop。

零注册,先看真实效果

  • 🔍 真实检测结果示例(含逐句标注 + 置信度 + 来源链接):https://aihcc.cloud/r/GttouoJfMpkC
  • 🛡️ CUA 动作分级在线体验(纯规则,不耗额度):https://aihcc.cloud/cua
  • 📝 网页版检测(免费额度 2 次/天):https://aihcc.cloud

工具集(4 个)

鉴权模型:客户端在各自机器配 Authorization: Bearer <你的 HallucC API key> 头 → server 提取并原样透传到后端 → 后端校验 + 扣同一账号额度。key 只在 HTTP 头里流转,不进工具参数、不进模型 transcript。

公网接入(推荐,无需本地运行)

MCP server 已部署在 https://aihcc.cloud/mcp(remote,streamable-http)。客户端直接配公网地址 + 个人 API key 即可:

# Claude Code
claude mcp add --transport http hallucc https://aihcc.cloud/mcp \
  --header "Authorization: Bearer <你的 HallucC API key>"

Cursor / Claude Desktop 同理,URL 填 https://aihcc.cloud/mcp,Headers 加 Authorization: Bearer 。API key 在 https://aihcc.cloud 注册后于 /keys 页创建,免费套餐每日有额度。

或:npx 本地运行(stdio,无需 clone)

{
  "mcpServers": {
    "hallucc": {
      "command": "npx",
      "args": ["-y", "hallucc-mcp"],
      "env": { "HALLUCC_API_KEY": "<你的 HallucC API key>" }
    }
  }
}

同一套工具,走 stdio 传输,key 从环境变量读取,默认连公网后端 https://aihcc.cloud。

本地运行(源码开发)

# 1. 装依赖(已装可跳过)
npm install

# 2.(可选)配置后端地址与端口;默认指向本机 8001
cp .env.example .env
#   HALLUCC_BASE_URL=http://127.0.0.1:8001
#   PORT=8787

# 3. 确保后端在跑:curl http://127.0.0.1:8001/health
# 4. 起 MCP server(dev 热重载)
npm run dev
# 或生产:npm start

服务监听 http://127.0.0.1:8787/mcp,健康检查 GET /health。

客户端接入

Claude Code(CLI)

# remote HTTP transport,带个人 key 头
claude mcp add --transport http hallucc http://127.0.0.1:8787/mcp \
  --header "Authorization: Bearer <你的 HallucC API key>"

# 验证
claude mcp list
# 在对话里调用:让 Claude 核验一段文本的幻觉 / 检测一段 prompt 的注入风险
