Proxy-based string replacement lets agents use API keys without ever seeing real credentials
viksit · x · 2026-09-07
Sharing a practical pattern for letting AI agents call APIs without exposing real credentials:
- All code runs inside a Docker container whose network traffic is forced through a proxy
- Every service key is a placeholder like OPENAIAPIKEY="PLACEHOLDER"
- The proxy inspects each request and string-replaces the placeholder with the real credential
The real keys never enter the agent's visible context, reducing leak risk in agentic workflows.
