# How do you make AI agents safe to query a Railway Postgres database?

*Domain Solution · Railway Postgres*

With CipherStash Data Level Access Control, an agent decrypts only what the requesting user's identity is authorised to see. Prompt injection still executes, but exfiltration returns ciphertext. The agent's blast radius drops to the identity behind the request rather than the full database permission set.

## Who's asking

Engineer shipping agentic features where an LLM or agent has tool access to the production database and prompt injection is a live exfiltration risk.
