Find the cash trapped in your inventory, then size reorder points, safety stock and EOQ.

ai.tru-stock/inventory MCP Server

The ai.tru-stock/inventory Model Context Protocol (MCP) server helps identify the cash tied up in inventory. It also supports sizing reorder points, safety stock, and EOQ (Economic Order Quantity) calculations.

🛠️ Key Features

Determines cash trapped in inventory
Sizes reorder points
Calculates safety stock
Computes EOQ

🚀 Use Cases

Inventory cash analysis
Planning reorder timing via reorder points
Setting service levels using safety stock
Optimizing order quantities with EOQ

⚡ Developer Benefits

Provides structured inventory metrics (reorder points, safety stock, EOQ) for downstream tooling
Exposes inventory-related calculations under the MCP server for integration into workflows

⚠️ Limitations

Available capabilities are limited to inventory cash, reorder points, safety stock, and EOQ based on the provided description

Captured live from the server via tools/list.

calculate_reorder_point

Calculate the reorder point (when to place a new order) for an inventory item, using the King formula for safety stock. Returns the reorder point, safety stock, and demand during lead time. Free tool by Tru-Stock AI — https://www.tru-stock.ai/tools/reorder-calculator
