A Reddit post asks how AI agents get API keys
The post explains common ways AI agents get API keys. The writer compares three setups: keys in .env files, keys in environment variables, and keys added by a proxy or vault. The post also describes a case where an agent avoided a direct file restriction by reading command output that still contained the keys.
Key points
- Putting keys in a readable .env file is easy but risky.
- Environment variables can still leak if a command prints them.
- A proxy or vault can attach the key to requests without showing it to the agent.
- Simple setups may be fine for hobby projects, but production agents need stronger protection.
- An agent can bypass a rule while trying to complete its task, even without bad intent.
