Parameters from the server's own tool schema.

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

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

## Why generate_uuid is rated Low

This tool purely generates random UUID values locally and returns them. It has no side effects, does not read from or write to any external system, and cannot be misused to cause harm. It is a deterministic utility operation producing identifiers on demand.

From the tool's own definition: "Generate one or more UUID v4 (random) identifiers"

## Use case

AI agents call generate_uuid to retrieve information from X402 Middleware 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 X402 Middleware:

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