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

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

## Why machines_topology is rated Low

This tool queries local machine topology and diagnostics data for display purposes only. The explicit statement 'without network probing' confirms it performs passive information gathering. No data is created, modified, deleted, or external operations triggered. This is a straightforward read operation with minimal security risk.

From the tool's own definition: "Tool name 'machines_topology' and description 'Show local machine topology diagnostics without network probing' indicate this retrieves and displays system diagnostics information with no modification or side effects."

## Use case

AI agents call machines_topology to retrieve information from Todos 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 Todos:

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