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

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

## Why delete_memory is rated Critical

This tool permanently removes stored memory entries. Deletion is an irreversible operation that cannot be undone, fitting the Destructive category. While the blast radius is constrained to memory artifacts rather than financial or system-critical resources, accidental or malicious deletion of important memories could significantly impact an AI agent's ability to maintain context or recall critical information.

From the tool's own definition: "Tool name is 'delete_memory' with description 'Delete a memory by key'. The verb 'delete' is explicitly destructive and irreversible. It removes data from the enhanced memory system without the ability to undo the operation."

## Use case

AI agents call delete_memory to permanently remove resources in Claude MCP Server Ecosystem, 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 Claude MCP Server Ecosystem:

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

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
