This is really interesting, I'll check it out. At least in its current form this seems like it would take some effort to setup - we're focusing heavily on making MCP Defender easy to setup in less than a minute and then forgetting about it as it runs in the background.

an admirable goal!

given the fallibility of LLMs, are you sure it's a good idea that they forget about it?

that seems like it has the same risks as having no security (perhaps worse, lulling people into a false sense of security)

are you sure the LLM doing security can't be tricked/attacked using any of the usual methods?
