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

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

  "method": "tools/call",

    "name": "create_inventory_category",
    "arguments": {}

## Why create_inventory_category is rated Medium

This tool creates new data (an inventory category) in a reversible manner. Creating a category can be undone by deletion. The blast radius is medium because creating duplicate or unwanted inventory categories could clutter the system and require manual cleanup, but it does not permanently destroy data or execute arbitrary code. It falls clearly under Write rather than Execute or Destructive.

From the tool's own definition: "The tool 'create_inventory_category' explicitly 'Create[s]' a category. The description confirms it creates a new inventory category with a default parent and validates uniqueness constraints."

Risk signals: Admin/system-level operation
