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

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

## Why number-param is rated Low

With no description and only a vague name suggesting it takes a numeric parameter, there is insufficient evidence to classify this as anything other than 'Other'. The name alone does not indicate any read, write, execute, destructive, or financial operation. Confidence is very low due to the lack of information.

From the tool's own definition: "Tool name is 'number-param' and description is empty; no information about what the tool does beyond accepting a numeric parameter."

## Use case

AI agents call number-param as a supporting operation in Mcp Test Servers workflows.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "number-param": {
      "limits": [
        {
          "counter": "number-param_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}
```
