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

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

## Why discover_table is rated Low

Although the tool registers dynamic CRUD tools (which could enable write/destructive actions), the tool itself performs schema discovery and registration—introspection activities that are fundamentally read operations. The registration of downstream tools does not alter the classification of this specific tool.

From the tool's own definition: "Tool name is 'discover_table' and description states it 'Discover[s] a ServiceNow table schema and register[s] dynamic CRUD tools for it.' The primary action is discovery and registration of schema information, which is a read operation that retrieves…"

## Use case

AI agents call discover_table to retrieve information from NowAIKit — ServiceNow AI Toolkit 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 NowAIKit — ServiceNow AI Toolkit:

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