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

```json
{
  "jsonrpc": "2.0",

  "params": {
    "name": "list_scans",
    "arguments": {}

```

## Why list_scans is rated Low

The 'list_' prefix is a standard convention for retrieval operations that query and return data without modification. Context from sibling tools confirms this server provides scanning and reporting capabilities where 'list' operations would enumerate existing scans. No destructive, write, execute, or financial operations are indicated.

From the tool's own definition: "Tool name 'list_scans' combined with sibling tools like 'list_reports' and 'list_vulnerabilities' suggests query/enumeration functionality. No description provided, but naming convention strongly implies data retrieval with no side effects."

## Use case

AI agents call list_scans to retrieve information from Hospital Vuln Scanner 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 Hospital Vuln Scanner:

```json
