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

```json
{
  "jsonrpc": "2.0",

  "params": {
    "name": "get_as_relationships",
    "arguments": {}

## Why get_as_relationships is rated Low

This tool retrieves and displays network topology information about Autonomous System relationships. It is a read-only operation with no side effects, no data modification, no code execution, and no destructive capabilities. The blast radius of misuse is minimal—an attacker could only gather publicly available BGP relationship information, which is typically non-sensitive network topology data.

From the tool's own definition: "Tool name and description indicate a query operation: 'Get AS-level relationships' retrieves relationship data for an Autonomous System without modification. Returns informational data about peer, upstream, and downstream relationships."

## Use case

AI agents call get_as_relationships to retrieve information from Cloudflare 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 Cloudflare:

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