Credential safety

Credential-less sandboxes

Mistle lets agents access connected services without placing provider credentials inside the sandbox. Approved outbound requests are routed through Mistle's credential proxy, where authentication happens outside the agent runtime.

Credentials stay encrypted in Mistle's control plane and are applied only when a request is authorized for the calling sandbox and organization.
