## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,

## Why delete_knowledge_category is rated Critical

This tool performs an irreversible deletion of a knowledge base category. Although documents are not permanently removed, the category itself and its associated organizational structure are destroyed and cannot be undone. This qualifies as Destructive rather than Write because deletion is not a reversible modification.

From the tool's own definition: "Tool name contains 'delete' and description states 'Delete a knowledge base category'; the action is irreversible—once deleted, the category structure is removed and cannot be recovered, even though documents within are preserved."

## Use case

AI agents call delete_knowledge_category to permanently remove resources in FlowDot MCP Server, 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 FlowDot MCP Server:

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