Re:Show HN: CtxVault – agent memory isolation enforced outside app code on Thursday March 05, 2026 @08:09AM (#47261176)

Previous Show HN: https://news.ycombinator.com/item?id=47136585. That version had the vault abstraction but access control lived entirely in application code — which is exactly the problem I was trying to solve.

This version adds server-side enforcement: access rules are declared via CLI and checked on every request, independent of what the agent implementation does. The boundary doesn't disappear if you write a bug.

Also added MCP server support, so Claude Desktop can use it with no integration code.

I build multi-agent systems and after a while the memory problem started to feel like the thing nobody had really solved properly.The obvious approach is a shared vector store with metadata filtering to separate what each agent can see. It works until someone writes a bug, adds a new code path, or bypasses the filter entirely — the boundary is only as strong as every line of application code...

Have you considered adding any kind of agent coordination layer, e.g. letting one “orchestrator” agent spawn and direct sub-agents on specific subtasks, rather than having the developer manually assign each task? Or is the explicit human-in-the-loop assignment a deliberate design choice to keep control and avoid runaway costs?

I’m also wondering whether there is actually a need for memory to become a controllable infrastructure layer that agents can integrate with, instead of everyone building custom memory management logic each time.

Do you think this is something that will become necessary in production agent systems, or is memory still mostly treated as an implementation detail today?

I built CtxVault while working on multi-agent systems and persistent memory patterns.Most agent architectures treat memory as a retrieval problem. Multiple agents share a vector store and rely on metadata filtering, routing logic, or prompt-level rules to control what each agent can see.In practice, this becomes hard to reason about as systems grow.Moreover, I found that memory in agent systems...
