Your Idea

Prompt injection is a significant security concern in any LLM application that processes user input.

I noticed that MCP has not deployed any prompt injection defenses in its framework.

I am researching the protection of LLM applications and have an idea: adopting randomization in prompts to mitigate prompt injection attacks. This approach is similar to ASLR in traditional software protection and introduces almost zero runtime overhead.

I am interested in contributing to the implementation of this feature and would like to hear your thoughts on it.
