Pigeon, a signed Pass for what a sub-agent may do
AI Digest
Pigeon Pass权限控制子代理MCP集成AI代理
文章介绍Pigeon工具通过Pass机制限制子代理权限，防止权限滥用。该方案通过签名凭证替代全权API密钥，实现细粒度权限控制。
Pigeon uses signed Passes to restrict sub-agent permissions, replacing full API keys with granular credentials for secure AI agent delegation.
Key points
- Pigeon Pass通过签名凭证限制子代理操作范围 Pigeon Pass restricts sub-agent actions with signed credentials
- 权限验证包含动作、资源、约束条件三要素 Verification checks action, resource, and constraints
- 子代理无法扩大权限或绕过父级约束 Sub-agents cannot escalate privileges or bypass parent constraints
- MCP中间件集成实现工具调用前验证 MCP middleware enforces tool calls with pre-verification
- 提供代码示例展示委托与验证流程 Code examples demonstrate delegation and validation
Takeaway: Pigeon通过细粒度权限控制提升AI代理安全性 / Pigeon enhances AI agent security through granular permission controls
