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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "delete_segment",
    "arguments": {}
  }

## Why delete_segment is rated Critical

The tool irreversibly deletes data (a segment) with no ability to recover or undo the action. This matches the Destructive category definition. While subscribers themselves are not deleted, the segment configuration is permanently removed.

From the tool's own definition: "Tool name is 'delete_segment' and description explicitly states 'Permanently delete a segment. This cannot be undone.'"

## Use case

AI agents call delete_segment 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)

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

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