Uninstall a second-generation package from the target org. Specify the package ID (starts with 04t) or alias for the package to uninstall.
AI agents call package_uninstall to permanently remove resources in Salesforce CLI MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Uninstalling a package permanently removes custom functionality, configurations, and potentially data dependencies from a live Salesforce org. While not as immediately catastrophic as deleting user data, package uninstallation is an irreversible action that can break org functionality and requires remediation.
