# NousResearch/hermes-agent · Anthropic credential leak fix: env token sent to third-party endpoints

## Open now

- Nothing open on GitHub.

These items address a bug where the ANTHROPIC_AUTH_TOKEN environment variable could be forwarded to non-Anthropic compatible endpoints alongside an api_key, resulting in unintended dual-credential exposure. The fixes ensure only one credential is sent and that the env-derived token is cleared on api-key-style clients.
