Token-based authentication is now supported for Amazon Bedrock Foundry alongside the existing ANTHROPIC_FOUNDRY_API_KEY. When ANTHROPIC_FOUNDRY_AUTH_TOKEN is set, it is used directly as a bearer token instead of deriving credentials from the API key.
Usage
export ANTHROPIC_FOUNDRY_AUTH_TOKEN="my-bearer-token"
claudeDetails
- Token-based auth is checked first; API key auth is used as fallback
- Useful when a bearer token is injected by infrastructure (e.g. IAM credential vending)
- Both variables are now shown in
