Don't Hand AI Agents Raw Credentials; Use Backend Proxy Isolation
WesEklund · x · 2026-07-15
This discussion focuses on credential management for AI agents:
- Do not give raw API keys directly to agents.
- Do not put secrets into system prompts.
- Do not let agents see real credentials that might be leaked in their responses.
The author recommends using proxy / backend isolation:
- The agent initiates an action request;
- Your backend performs validation first;
- The backend holds the real credential and executes the action;
- The agent only receives an opaque token.
This way, even if the agent is compromised, the attacker only gets a restricted token rather than a directly exploitable real key. The author compares this to never putting database passwords in frontend JS, arguing this principle should equally apply to AI agents.
