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

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

## Why http_client is rated High

An HTTP client tool that can make requests to arbitrary URLs is an Execute-category tool — it triggers external operations whose effects depend on arguments. It could be used to send requests to any endpoint, potentially causing side effects on external systems (POST, PUT, DELETE requests, etc.). The severity is high because misuse could result in unintended external operations.

From the tool's own definition: "Tool name 'http_client' with empty description. The name strongly implies making arbitrary HTTP requests to external URLs/endpoints."

## Use case

AI agents invoke http_client to trigger actions in GadgetHumans API Hub. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches GadgetHumans API Hub:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "http_client": {
      "limits": [
        {
          "counter": "http_client_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```
