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

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

    "name": "update_scoped_app",
    "arguments": {}

## Why update_scoped_app is rated Medium

This tool modifies existing ServiceNow scoped applications without irreversibly deleting data. While it requires explicit write enablement (suggesting organizational controls), the update operation is reversible through additional updates or rollbacks.

From the tool's own definition: "Tool explicitly performs 'update' on a 'scoped application' and requires 'WRITE_ENABLED=true', confirming it modifies existing data reversibly."

## Use case

AI agents use update_scoped_app to create or update resources in ServiceNow MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ServiceNow MCP Server environment.

## Recommended policy (PolicyLayer)
