LoopIn MCP Server
LoopIn
用于 AI 智能体的人机交互中断 API。
LoopIn 让 AI 智能体能够在关键决策点暂停,请求人工审核,并根据人类的决定恢复执行。不再让智能体独自做出高风险决策。
为什么选择 LoopIn?
自主智能体功能强大——直到它们遇到不应在没有人类参与的情况下做出的决策。LoopIn 为每个智能体提供了一个安全出口:
智能体到达决策点 → 调用
POST /interruptsLoopIn 通知人类 → 通过 Webhook 或直接审核 URL
人类批准或拒绝 → 通过审核页面或
POST /interrupts/:id/decide智能体轮询决策 →
GET /interrupts/:id智能体恢复 → 使用该决策(以及人类提供的任何修改后的参数)

"reviewUrl": "http://localhost:3002/review/3f4e2a1b-..."
}GET /interrupts/:interruptId
轮询当前状态和决策。
响应(待处理):
{
"interruptId": "3f4e2a1b-...",
"status": "pending",
"action": "Transfer $4,200 to vendor account ending in 9821",
"context": { ... },
"urgency": "high",

"expiresAt": "2024-04-12T14:30:00Z",
"reviewUrl": "http://localhost:3002/review/3f4e2a1b-..."
}响应(已解决):
{
"interruptId": "3f4e2a1b-...",
"status": "approved",
"decision": "approved",
"decidedAt": "2024-04-12T13:07:22Z",
"reason": "Invoice verified, proceed."
}POST /interrupts/:interruptId/decide
提交人类决策。
请求:
{
"decision": "approved",
"reason": "Invoice verified, proceed.",
"modifiedParams": { "amount": 4200 }
}响应:
{
"interruptId": "3f4e2a1b-...",
"status": "resolved",
"decision": "approved",
"decidedAt": "2024-04-12T13:07:22Z"
}GET /interrupts/pending/:userId
列出所有等待用户审核的待处理中断。
响应:
[
{
"interruptId": "3f4e2a1b-...",
"action": "Transfer $4,200 to vendor...",
"urgency": "high",
"createdAt": "...",
"expiresAt": "...",
"reviewUrl": "..."
}
]DELETE /interrupts/:interruptId
取消待处理的中断(智能体不再需要该决策)。
GET /analytics/:userId
使用统计信息。
响应:
{
"userId": "user-123",
"totalInterrupts": 47,
"approvalRate": 0.83,
"avgResponseTimeMs": 142000,
"byStatus": { "approved": 39, "rejected": 8 },
"byUrgency": { "high": 12, "medium": 28, "low": 7 },
"topActionTypes": [
{ "action": "Send payment", "count": 18 },
{ "action": "Delete records", "count": 9 }
]
}审核页面
每个中断都有一个人类可读的审核 URL:
GET /review/:interruptId这将渲染一个 HTML 页面,显示:
智能体想要做什么
所有上下文数据(格式化的 JSON)
紧急程度徽章
批准 / 拒绝 按钮
可选的理由文本框
将此 URL 分享给需要审核请求的任何人。默认无需登录。
MCP 工具
LoopIn MCP 服务器公开了 6 个工具,供任何兼容 MCP 的 AI 客户端(Claude Desktop、Cursor 等)使用:
工具 | 描述 |
| 智能体创建新的中断请求 |
| 智能体轮询决策 |
| 人类查看需要审核的内容 |
| 人类批准或拒绝 |
| 智能体取消待处理请求 |
| 使用统计信息 |
MCP 服务器设置 (stdio)

"mcpServers": {
"loopin": {
"command": "npx",

}智能体使用模式
1. Agent reaches a decision point
→ POST /interrupts { agentId, userId, action, context, urgency }
← { interruptId, reviewUrl }
2. Agent saves interruptId and pauses
→ (optionally: notify human via other channels with reviewUrl)
3. Agent polls until resolved
→ GET /interrupts/:interruptId
← { status: "pending" } ← keep polling
← { status: "approved", decision, modifiedParams } ← resume
4. Agent resumes execution
→ use modifiedParams if provided, otherwise proceed as planned人类使用模式
选项 A — 审核 URL(最简单)
从智能体接收
reviewUrl(通过电子邮件、Slack 等)在任何浏览器中打开该 URL
查看上下文,点击“批准”或“拒绝”,添加可选理由
完成 — 智能体将在下一次轮询时获得决策
选项 B — 列出待处理(仪表板)
GET /interrupts/pending/:userId— 查看所有打开的请求打开单独的
reviewUrl或直接调用POST /interrupts/:id/decide
环境变量
变量 | 默认值 | 描述 |
|
| API 服务器端口 |
|
| 审核链接的公共基础 URL |
| (无) | 可选:要求所有请求包含 |
Colossal API 产品组合
LoopIn 是 Colossal API 基础设施 API 套件的一部分,专为 AI 智能体设计:
SubRadar — 订阅检测与取消
