WHAT IT DOES

What delete_group_file does on NapCat MCP Server

AI agents call delete_group_file to permanently remove resources in NapCat MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why delete_group_file is rated Critical

This tool performs irreversible deletion of group files. Deletion operations cannot be reversed and result in permanent loss of data. While the blast radius is confined to group files (not system-critical), the destructive nature and potential impact on group collaboration and data integrity classify this as Destructive with high severity.

From the tool's definition Tool name 'delete_group_file' and description 'Delete group file' explicitly indicate irreversible deletion of data. The verb 'delete' is a destructive operation that cannot be undone.

RECOMMENDED RULE

The rule that runs delete_group_file safely

PolicyLayer is an MCP gateway: it sits between your AI agents and NapCat MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For delete_group_file, this is the rule to start with:

delete_group_file Hidden

delete_group_file is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
