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

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

## Why fluent_explain is rated High

'Run' is a direct indicator of Execute category—the tool triggers code execution. Without a detailed description, confidence is moderate (0.65) rather than high, but the Execute classification is warranted because 'Run' inherently means executing something. Severity is high because arbitrary execution in ServiceNow could affect workflows, data, and business processes depending on what is executed.

From the tool's own definition: "Tool name 'fluent_explain' with description 'Run' indicates execution of code or logic. The 'Run' verb combined with context of a ServiceNow MCP server suggests this triggers server-side operations whose effects depend on runtime arguments."

## Use case

AI agents invoke fluent_explain to trigger actions in ServiceNow MCP Server. 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 ServiceNow MCP Server:

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