在AWS Lambda上保护MCP工具免受提示注入攻击

提示注入对与语言模型交互的工具构成了重大的安全风险,尤其是在模型上下文协议(MCP)中。本文详细介绍了如何使用TypeScript和Serverless Framework在AWS Lambda上构建安全的MCP服务器。核心原则是将所有第三方内容视为不受信任的数据,实施严格的代码级保护措施,而不是仅仅依赖系统提示。关键策略包括标记不受信任的内容、严格检查参数、按权限隔离工具,以及要求对敏感写入操作进行人工确认,以防止数据泄露。 AI

影响 通过详细介绍针对提示注入的代码级防御措施,增强了AI工具的安全性,这对于与外部数据交互的代理至关重要。

    Prompt Injection in MCP: Securing Lambda Tools

    <p>Prompt injection in MCP is, in my view, the security topic people underestimate most when they build their own tools. An MCP server is quick to build, a few tools are registered, and the agent calls them dutifully. Then one of those tools reads a text that somebody else wrote.…
