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

```json

  "jsonrpc": "2.0",

## Why get_switch_spanning_tree is rated Low

This tool retrieves spanning tree protocol information from a switch for monitoring and diagnostic purposes. It queries existing network state without modifying, deleting, or executing external operations. The 'get' prefix and lack of modification keywords (create, update, delete, apply) strongly indicate a read-only information retrieval function.

From the tool's own definition: "Tool name 'get_switch_spanning_tree' uses the 'get' verb, which typically indicates a retrieval operation. The spanning tree is a network topology protocol state that is read-only in nature."

## Use case

AI agents call get_switch_spanning_tree to retrieve information from API-Central 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 API-Central:

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