Delete a storage credential with parameter: name (required)
AI agents call delete_storage_credential to permanently remove resources in Databricks Permissions MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a storage credential is an irreversible action that destroys access configuration. This prevents legitimate users from accessing storage resources and cannot be undone without manual recreation. The high severity reflects that loss of storage credentials can disrupt data pipelines, cause application failures, and potentially expose misconfigurations during recovery attempts.
From the tool's definition Tool name is 'delete_storage_credential' and description states 'Delete a storage credential'. The verb 'delete' combined with 'storage_credential' indicates irreversible removal of authentication material used to access cloud storage.
