Implementation Reference

• src/index.ts:573-590 (handler)

  The handler function for the 'check_inventory' tool. It filters the mock inventory data based on the search parameter (product name, SKU, or category) and returns detailed stock information including low stock warnings.

  case 'check_inventory': {
    const search = String(args?.search || '').toLowerCase();
    const results = storeData.inventory.filter(item =>
      item.name.toLowerCase().includes(search) ||
      item.id.toLowerCase().includes(search) ||
      item.category.toLowerCase().includes(search)
    );
    return {
      content: [{
        type: 'text',
        text: results.length > 0
          ? `Found ${results.length} item(s):\n\n${results.map(item => 
              `${item.name} (${item.id})\n- Category: ${item.category}\n- Stock: ${item.quantity} units${item.quantity <= item.reorderLevel ? ' ⚠️ LOW STOCK' : ''}\n- Price: $${item.price}\n- Supplier: ${item.supplier}\n- Last Restocked: ${item.lastRestocked}`
            ).join('\n\n')}`
          : `No items found matching "${args?.search}"`
      }]
    };
  }

• src/index.ts:68-78 (schema)

    description: 'Check current inventory levels for a specific product or category. Returns stock quantity, reorder status, and supplier information.',
    inputSchema: {
      type: 'object',
      properties: {
        search: { type: 'string', description: 'Product name, SKU, or category to search for' },
      },
      required: ['search'],
    },
  },

• src/index.ts:516-518 (registration)
