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

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

  "method": "tools/call",
  "params": {
    "name": "custom_delete_static_list",
    "arguments": {}

## Why custom_delete_static_list is rated Critical

Deleting a static list permanently removes lead data and cannot be undone. This is a destructive operation with high blast radius if misused by an AI agent—it could eliminate critical contact databases, segments, or audiences. The custom API wrapper and lack of detailed operation description slightly lower confidence from critical to high, but the destructive nature of deletion is clear.

From the tool's own definition: "Tool name contains 'delete' and 'static_list'; description indicates it calls Marketo REST API directly for custom operations. The 'delete' operation on a static list (a collection of leads/contacts in Marketo) is irreversible data removal."

## Use case

AI agents call custom_delete_static_list to permanently remove resources in Marketo 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 Marketo MCP Server:

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