## Why crm_delete_segment is rated Critical

This tool permanently removes a segment from the CRM system, which is a Destructive action (irreversible data deletion). The high severity reflects that deletion breaks dependent outreach campaigns, creating cascading effects that require manual intervention to repair. The confidence is high because the name 'delete' and description unambiguously indicate permanent removal.

From the tool's own definition: "'Delete a segment' indicates irreversible deletion; the description explicitly states 'Outreach campaigns referencing it will fail until reassigned,' showing destructive side effects that cannot be automatically undone."

## Use case

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

## Recommended policy (PolicyLayer)

Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Munin:

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "crm_delete_segment"
