Server signers are the standard for server-side and agent operations. Unlike API key signers — which used your primary API key as the signing mechanism itself — server signers are dedicated signing credentials, giving you stronger isolation and a smaller blast radius if credentials are ever rotated or compromised.API key signers are deprecated and will be removed in a future release. To take advantage of the improved security model, migrate any server-side or agent workflows to server signers. Configuration
