No. The Credential Vault stores every credential encrypted at rest on AgentPMT servers and injects it server-side at the moment the outbound request leaves for the upstream API. The agent sees the endpoint name and the response, never the raw key, token, or password.
This is enforced by the connected-API builder: every endpoint must select an injection target (header, body, or query parameter) before it can be saved, and the credential value is bound once and never re-emitted to the agent context or the agent memory.
