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

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

  "method": "tools/call",
  "params": {
    "name": "lookup_useragents_top",

## Why lookup_useragents_top is rated Low

This tool retrieves static reference data (User-Agent strings) for use in scraping workflows. It does not execute code, modify data, delete anything, or commit financial transactions. While the server charges per call (a financial transaction by the server operator), the tool itself merely returns data.

From the tool's own definition: "Tool description explicitly states 'Get the top 50 real-world browser User-Agent strings' — a retrieval operation with no side effects. The verb 'Get' and absence of any modification, deletion, or execution capability confirms this is a read-only lookup."

## Use case

AI agents call lookup_useragents_top to retrieve information from GoCreative Agent API 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 GoCreative Agent API:

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