## Why knowledge_delete is rated Critical

The 'delete' operation in a content management context typically removes data that cannot be recovered. This is categorized as Destructive rather than Write because deletion is irreversible. Severity is high because accidental or malicious deletion of knowledge/brand assets could cause significant operational harm, though without full documentation, a critical rating is not assigned.

From the tool's own definition: "Tool name 'knowledge_delete' explicitly indicates deletion. While the description is empty, the verb 'delete' signals irreversible data removal."

## Use case

AI agents call knowledge_delete to permanently remove resources in Postking Mcp, 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 Postking Mcp:

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