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

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

```

## Why delete_relationship is rated Critical

The 'delete_' verb combined with the operational context of an entity-relationship system (evidenced by sibling tools like create_relationship, create_entity, create_observation, etc.) indicates this tool permanently removes relationship records. This is irreversible data modification, placing it in the Destructive category rather than Write.

From the tool's own definition: "Tool name is 'delete_relationship' with no description provided. The 'delete_' prefix and sibling tools like 'delete_entity' and 'delete_observation' indicate this tool removes data irreversibly."

## Use case

AI agents call delete_relationship to permanently remove resources in Optimized Memory MCP Server V2, 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 Optimized Memory MCP Server V2:

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