Find the cash trapped in your inventory, then size reorder points, safety stock and EOQ.
Tru-Stock AI is a remote MCP server published at www.tru-stock.ai. It has been probed 15 times since 9/12/2026. It answered in 15 of them (100.0%), a near-uninterrupted record. Median response time is 1,521 ms, a delay an agent will notice. It offers a narrow, focused set of 7 tools. On the protocol side it still runs 2025-11-25 and has not moved to the newer spec.
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
calculate_safety_stock — Parameter 'serviceLevel' is a string but lacks format examples (e.g., '95%' or 'Z-score').calculate_lead_time — All parameters are optional, making it unclear what inputs are necessary for meaningful results.tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
Tools the server advertised in the latest measurement — measured, not catalog-claimed.
calculate_reorder_pointCalculate 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
avgDailyDemandnumberrequiredleadTimeDaysnumberrequireddemandStdDevnumberleadTimeStdDevnumberserviceLevelstringcalculate_safety_stockCalculate how much safety stock to hold to protect against demand and lead-time variability, using the King formula. Returns units and the capital tied up. Free tool by Tru-Stock AI — https://www.tru-stock.ai/tools/safety-stock-calculator
avgDailyDemandnumberrequireddemandStdDevnumberavgLeadTimeDaysnumberrequiredleadTimeStdDevnumberserviceLevelstringunitCostnumbercalculate_economic_order_quantityCalculate the Economic Order Quantity (EOQ) — the order size that minimises combined ordering and holding cost. Returns EOQ, orders per year, and total annual cost. Free tool by Tru-Stock AI — https://www.tru-stock.ai/tools/eoq-calculator

Returns a RANGE rather than a single number when inputs are left at their defaults, because those defaults are assumptions about your business.

Each block is one measurement round. Green: working response. Amber: responded but the server was returning errors (5xx). Red: no response at all.
Each cell is one probe run. Faded cells are incomplete probes — one leg did not answer, so the era is inconclusive.
The two probe legs separately: modern server/discover and legacy initialize.
