## Why cdp_cache_delete_by_key is rated Critical

This tool permanently removes data (cache entries) by key, which cannot be undone. This matches the Destructive category definition: 'irreversibly deletes or overwrites data, or actions that cannot be undone.' The high severity reflects that an agent with poor input validation could delete critical cache entries that other operations depend on, potentially breaking workflows or data pipelines across the CDP system.

From the tool's own definition: "Tool name explicitly contains 'delete' and description states 'Delete a cache entry by explicit key.' The operation is irreversible—once deleted, the cache entry cannot be recovered without external restoration."

## Use case

AI agents call cdp_cache_delete_by_key to permanently remove resources in CDP 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 CDP MCP Server:

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