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

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

## Why analyze_transaction_wraparound is rated Low

This tool retrieves and analyzes transaction ID wraparound metrics from PostgreSQL to assess risk status. It performs no writes, deletes, code execution, or financial operations. Misuse by an AI agent would only expose monitoring data without causing damage, warranting low severity classification.

From the tool's own definition: "Tool name 'analyze_' and description 'Monitor transaction ID wraparound risks' indicates data retrieval and diagnostic inspection with no modification, deletion, or execution of external operations."

## Use case

AI agents call analyze_transaction_wraparound to retrieve information from Postgres 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 Postgres:

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