What crm_marketplace_uninstall does on 0nmcp
AI agents call crm_marketplace_uninstall to permanently remove resources in 0nmcp, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why crm_marketplace_uninstall is rated Critical
Uninstall operations permanently remove software and cannot be trivially undone without reinstallation and reconfiguration. While not a direct data deletion tool, uninstalling an app from a CRM system removes business functionality and may cascade to loss of integrations, workflows, or data access. This merits Destructive rather than Write (which are reversible).
From the tool's definition 'Uninstall a marketplace app from a location' – uninstall is an irreversible removal action that deletes/disables app functionality and associated data or configurations.
