What it can do
Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.
inventoryplanner_list_variantsList product variants with Inventory Planner's computed metrics (forecast, replenishment, days to sell out, lost revenue, lead time, review period and ~200 more). Always pass `fields` to pick the metrics you need (default: id,sku,lead_time,review_period,replenishment,oos,under_va
inventoryplanner_get_variantOne variant by its Inventory Planner id, with the metrics named in `fields` (default: id,sku,lead_time,review_period,replenishment,oos,under_value). GET /api/v1/variants/{id}.
inventoryplanner_list_variant_vendorsThe vendors a variant can be ordered from, with cost_price, landing_cost_price, vendor_reference (vendor SKU), vendor_name, vendor_packaging (MOQ) and uom_ordering. GET /api/v1/variants/{id}/vendors.
inventoryplanner_get_variant_vendorOne vendor's terms for a variant: cost_price, landing_cost_price, vendor_reference, vendor_name, vendor_packaging (MOQ), uom_ordering. vendor_id is the vendor name in lowercase. GET /api/v1/variants/{id}/vendors/{vendor_id}.
inventoryplanner_list_purchase_ordersList stock orders: purchase orders, transfers and assembly orders (the `type` field is "po"/empty, "transfer" or "assembly"). Filter with `filters`, e.g. {"status": "OPEN", "vendor": "Acme", "expected_date_lt": "2026-11-01"}. Default fields: id,reference,status,type,vendor,wareho
inventoryplanner_get_purchase_orderOne purchase order, transfer or assembly order by id, with its header fields (reference, status, vendor, warehouse, dates, addresses, totals, notes) and line items. GET /api/v1/purchase-orders/{id}.
inventoryplanner_list_purchase_order_itemsThe line items of a purchase order: variant id, sku, title, ordered quantity (replenishment), received quantity and received_history, cost price, tax, discount and stock snapshots. GET /api/v1/purchase-orders/{id}/items.
inventoryplanner_get_purchase_order_connectionsWhether and how a purchase order was saved to connected systems (ERP, accounting): per connection the status (success, error, run, queued), save_po flag and the PO's id and reference there. Read-only. GET /api/v1/purchase-orders/{id}/connections.
inventoryplanner_get_purchase_order_stock_updateThe stock updates a purchase order has computed: per warehouse (wh) the items with stock_before, delta and error. for_destination false reads the source warehouse of a transfer. Read-only: nothing is pushed. GET /api/v1/purchase-orders/{id}/stock-update.
inventoryplanner_create_draft_purchase_orderWRITE: create a purchase order with status "draft" in Inventory Planner (POST /api/v1/purchase-orders). A draft is only a plan inside Inventory Planner: it is NOT sent to the vendor, NOT saved to any connected system and moves no stock or money. Purchase orders only (no transfers
inventoryplanner_update_draft_purchase_orderWRITE: change the reference, expected date or notes of a purchase order that is still a draft (PATCH /api/v1/purchase-orders/{id}). The order is read first and refused unless its status is "draft". It never changes the status, sends the order, or touches line items or received qu

Common questions
Is Inventory Planner MCP by usefulapi safe?
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.22.3) reached the registry yesterday.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Spree Commerce: open-source B2B and marketplace ecommerce, Stripe MCP, MCP Cn Commerce
