  "jsonrpc": "2.0",

## Why delete_tag is rated Critical

This tool permanently removes tags from the system and detaches them from all associated subscribers. Permanent deletion with explicit 'cannot be undone' language qualifies as Destructive. While the blast radius is somewhat contained (tags are metadata, not core subscriber data), the irreversibility and scale (all subscribers) warrant 'high' severity.

From the tool's own definition: "'Permanently delete a tag and remove it from all subscribers. This cannot be undone.' — The tool irreversibly deletes data across multiple records (all subscribers using that tag) with no undo capability."

## Use case

AI agents call delete_tag to permanently remove resources in Sequenzy Mcp, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_tag"
  ]
}
```
