Delete a credential from the vault.
AI agents call gateway_delete_credential to permanently remove resources in Claude Team MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly removes authentication credentials from secure storage. Deletion of credentials cannot be undone and could cause immediate harm: service outages, broken integrations, inability to authenticate to critical systems, or require emergency credential rotation across dependent services. The blast radius is critical since credentials are foundational to system security and access control.
From the tool's definition Tool name 'gateway_delete_credential' explicitly states 'delete' combined with 'credential' and 'vault'. Description confirms 'Delete a credential from the vault', using the irreversible action verb 'delete'.
