- Server: Enhanced Knowledge Graph Memory Server (`danielsimonjr/memory-mcp`) — https://policylayer.com/tools/danielsimonjr-memory-mcp.md
- Homepage: https://github.com/danielsimonjr/memory-mcp
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no

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

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

## Why get_graph_stats is rated Low

This tool performs a query operation to retrieve statistical metadata about the knowledge graph. It has no side effects, does not create, modify, or delete data, and does not execute external operations. It falls squarely within the Read category as a data retrieval operation. The low severity reflects the minimal risk of misuse—an AI agent retrieving statistics poses no threat to data integrity or system operations.

From the tool's own definition: "Tool named 'get_graph_stats' with description 'Get statistics about the knowledge graph' - retrieves aggregate information about graph structure and contents without modifying any data."

## Use case

AI agents call get_graph_stats to retrieve information from Enhanced Knowledge Graph Memory Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Enhanced Knowledge Graph Memory Server:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_graph_stats": {}
  }
}
```

## 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`
