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

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

## Why list_data_sources is rated Low

This tool retrieves and lists metadata about data source definitions (file, JDBC, REST loaders) in ServiceNow's Import Set system. It queries existing configurations without creating, modifying, deleting, or triggering any operations. The action is purely informational and read-only, posing minimal risk even if invoked by an AI agent with incorrect context.

From the tool's own definition: "Tool name 'list_data_sources' and description 'List Import Set data source definitions' indicate a query/retrieval operation with no modification or execution of external systems."

## Use case

AI agents call list_data_sources to retrieve information from ServiceNow-MCP 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 ServiceNow-MCP:

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