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.
extensiv_list_facilitiesList the warehouse's facilities with their ids and properties (facility ids are needed for orders, stock details and receivers). GET /properties/facilities.
extensiv_list_carriersList the carriers with their shipment services (modes) and billing codes, the values an order's routingInfo and billingCode must use. GET /properties/carriers.
extensiv_list_customersList the warehouse's customers (the companies whose goods it stores), with their customer ids. GET /customers.
extensiv_get_customerOne customer by customer id: company info, contacts and settings. GET /customers/{customer_id}.
extensiv_list_itemsList the items (SKUs) of one customer, with item ids, descriptions and units. Filter with rql, for example `sku==ABC-1`. GET /customers/{customer_id}/items.
extensiv_list_ordersList outbound orders matching an RQL filter, for example `ReadOnly.CustomerIdentifier.id==1` or `readonly.processDate=gt=2026-10-01T00:00:00` (orders closed after that time). Use detail=OrderItems to include the line items. Orders carry the ship-to name, address and contact detai
extensiv_get_orderOne order by its transaction id (the order id from extensiv_list_orders): status, ship-to, routing, and with detail=OrderItems the lines. GET /orders/{transaction_id}.
extensiv_list_stock_summariesInventory totals per item and facility (on hand, allocated, available). Filter with rql, for example `ItemId==123` or a customer filter. GET /inventory/stocksummaries.
extensiv_list_inventoryInventory detail lines (location, lot, quantities). Filter with rql, for example `itemIdentifier.sku==SF-Box-DG`. GET /inventory.
extensiv_list_stock_detailsAll inventory of one customer in one facility, broken out by receive item (lot number, serial number and other track-by values). Both ids are required. GET /inventory/stockdetails.
extensiv_list_receiversList inbound receivers (receipts of goods), for example `ReadOnly.CustomerIdentifier.id==1`. Use detail=ReceiveItems for the lines. GET /inventory/receivers.
extensiv_get_receiverOne receiver by its transaction id. GET /inventory/receivers/{transaction_id}.
extensiv_list_receiver_itemsThe line items of one receiver, with item details. GET /inventory/receivers/{transaction_id}/items.
extensiv_list_purchase_ordersList inbound purchase orders per customer. Filter with rql, sort with sort. GET /inventory/pos.
extensiv_create_orderWRITE: submit a new outbound order for a customer and facility (the warehouse will pick and ship it). Not idempotent: calling twice creates two orders, so check extensiv_list_orders for the reference_num first. Needs ids from extensiv_list_customers, extensiv_list_facilities and
extensiv_cancel_orderWRITE: cancel one order by transaction id, with a reason and an optional cancellation fee. This cannot be undone; the order must be in a state the warehouse can still cancel (otherwise Extensiv answers with an error). The tool first reads the order to get the ETag Extensiv requir

Common questions
Is Extensiv 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 (1.6.3) 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?

Connect
- Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste
https://extensiv.usefulapi.io/mcp. - Claude Code:
claude mcp add --transport http extensiv https://extensiv.usefulapi.io/mcp, then run/mcpto log in. - VS Code: Add to VS Code.
- Cursor and other clients: add the URL as a remote MCP server:
{
"mcpServers": { "extensiv": { "url": "https://extensiv.usefulapi.io/mcp" } } }
Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Extensiv credentials.
