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

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

## Why get_speed_histogram is rated Low

This tool queries and retrieves historical speed test analytics (histogram data showing distribution of bandwidth, latency, or jitter metrics). It performs no writes, deletions, code execution, or financial transactions. The action is purely observational—fetching pre-computed statistical data about network performance.

From the tool's own definition: "Tool name 'get_speed_histogram' and description 'Get speed test histogram data. Shows distribution of speed test results' indicate a retrieval operation with no modification or side effects."

## Use case

AI agents call get_speed_histogram 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_speed_histogram": {}
  }
}
```
