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

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

## Why delete_instance_knowledge is rated Critical

The tool performs an irreversible deletion operation on knowledge documents. This is a Destructive action (cannot be undone), which ranks higher in severity than Write or Execute. High severity because inadvertent deletion of knowledge documents could impact business operations and data integrity, though blast radius is somewhat limited to a private instance rather than shared/production data.

From the tool's own definition: "Tool name contains 'delete' and description states 'Delete a knowledge document from your private subscribed instance' — this irreversibly removes data."

## Use case

AI agents call delete_instance_knowledge to permanently remove resources in ProAgentStore, 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 ProAgentStore:

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