Run these commands. The second one opens the login page:
Other MCP clients (Windsurf, Cline, Zed and more): add the URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser. Do not add an Authorization header: see Before you connect.
Find orders by status or reference and inspect their addresses, product lines and shipment tracking numbers.
zenfulfillment_list_orders zenfulfillment_get_order

zenfulfillment_list_stock
List inbound shipments and compare announced and arrived quantities for a selected shipment.
zenfulfillment_list_inventory_shipments zenfulfillment_get_inventory_shipment

The login page asks for your Zenfulfillment API key and Environment.
Zenfulfillment support issues API keys: write to [email protected] and ask for an API key for your account. Use Production for your live warehouse, or Test mode for a test key (it does not touch live data or your shop). Requested order, buyer and return records pass to your chosen AI client and its LLM provider. When requested, tools can create or update orders that trigger paid fulfillment and shipping, cancel eligible orders, or mark returns done (status only; no refund is paid). Ask Zenfulfillment to revoke or replace this key to stop vendor access. Billing is per key and environment; rotating the key starts a new usage and billing identity.
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: the login page asks for your Zenfulfillment API key and Environment. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
Turn on the Zenfulfillment connector, then ask in plain words. The AI picks the tools.
| Tool | Type | What it does |
|---|---|---|
zenfulfillment_list_orders | read | List orders List or search the fulfillment orders of this Zenfulfillment account (warehouse pick/pack/ship), with status, order reference, shop order number, totals, shipping and billing address, the products ordered/shipped and shipments (tracking number, carrier). Filter by ONE status, created/updated time or free text. The export has one row per product line; rows are grouped into orders. Paging: pass next_page back as page; an empty page is the end. GET /orders/export. |
zenfulfillment_get_order | read | Get order One order by its EXTERNAL reference, i.e. the order number from the connected shop or from your own import (for example 332-11-5599), with addresses, products with quantities (ordered, shipped, returned, refunded) and shipments with tracking numbers. Not the ZF reference: use zenfulfillment_list_orders with query for that. GET /orders/external/{reference}. |
zenfulfillment_list_stock | read | List stock levels Stock on hand in the Zenfulfillment warehouse per SKU (sku, quantity_on_stock). Filter by SKU text and/or a maximum quantity to find low stock (then sorted lowest first). GET /products/export. |
zenfulfillment_list_inventory_shipments | read | List inbound shipments List inbound inventory shipments (goods you sent to the warehouse) with reference, SKU lines, announced quantity, quantity arrived and note. Filter by ONE status, created/updated time or free text (ZF number, tracking code, type). Rows are grouped per shipment. Paging as in list_orders. GET /inventory_shipments/export. |
zenfulfillment_get_inventory_shipment | read | Get inbound shipment One inbound inventory shipment by its ZF reference (for example ZF01123700): SKU lines with announced and arrived quantities and the note. GET /inventory_shipments/export/{reference}/reference. |
zenfulfillment_list_returns | read | List returns List returns processed by the warehouse (PROCESSED = received, DONE = marked refunded), with the return's `_id` (needed by zenfulfillment_mark_return_done), ZF reference, note, products with quantity, reason, condition and whether they were actually returned, and the original order. Filter by ONE status, time or free text. Paging as in list_orders. GET /returns/export. |
zenfulfillment_import_order | write | Create or update an order WRITE: send ONE order to the Zenfulfillment warehouse for picking, packing and shipping to the given address (fulfillment and shipping fees apply per the contract). The reference is your own order number: a reference that already exists UPDATES that order instead of creating a new one. Each item becomes one CSV row (Reference;Date;Name;Company;Street1;Street2;Zip Code;City;Region;Country;Email;Phone;SKU;Quantity). Use SKUs from zenfulfillment_list_stock. Check the address with the user first. In test mode nothing ships. POST /orders/import. |
zenfulfillment_cancel_orders | write | Cancel orders WRITE, cannot be undone: cancel orders by reference (up to 50). Only orders that can still be cancelled (before the warehouse has packed or shipped them) are cancelled; the others come back in `errors`. Confirm the references with the user first. POST /orders/cancel. |
zenfulfillment_mark_return_done | write | Mark return as refunded WRITE: set a return's status to DONE (refunded) in Zenfulfillment. Zenfulfillment only records the status; refund the customer in your shop yourself. Use the `_id` from zenfulfillment_list_returns (not the ZF reference). Cannot be set back through the API. POST /returns/{returnId}/done. |
zenfulfillment_usage_status | Usage status (free-tier meter) Report the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter. | |
zenfulfillment_request_feature | Request a missing feature Tell usefulapi that the user needs something the Zenfulfillment tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter. | |
zenfulfillment_upgrade | Upgrade to Pro (unlimited*) Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on Zenfulfillment (the free tier caps monthly usage). Plans: "monthly" — $9/month; "yearly" — $90/year (2 months free). Cancel any time: Pro then runs to the end of the paid period, so it also suits a one-time job. *A fair use limit applies. For heavy use (near Pro's limit): "plus" or "plus_yearly" — Pro+, $39/month or $390/year, unlimited tool calls (fair use limit: 100,000 a month); an existing Pro subscription changes to Pro+ in place (needs confirm: true; the price difference for the rest of the period is charged at once). Otherwise returns a short link to open in your browser (it opens Stripe Checkout); after payment the account upgrades automatically. Does not count against the meter. | |
zenfulfillment_cancel_subscription | Cancel the Pro subscription Cancel the caller's Zenfulfillment Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run zenfulfillment_upgrade later to undo the cancel before the period ends. Does not count against the meter. |
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper API key and environment | $9/mo · $90/yr | Unlimited* |
*Pro fair use limit: 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this Zenfulfillment server only. Subscribe with zenfulfillment_upgrade (it returns a Stripe Checkout link). Cancel any time with zenfulfillment_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running zenfulfillment_upgrade before then undoes the cancel. Or write to [email protected].

No. usefulapi is an independent service. It is not affiliated with or endorsed by Zenfulfillment. The server calls the Zenfulfillment API with your own Zenfulfillment access, so it sees only the data that your account can see.
Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.
The login page asks for your Zenfulfillment API key and Environment. See Before you connect for where to find them.
No. 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: the login page asks for your Zenfulfillment API key and Environment. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Zenfulfillment API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in Zenfulfillment.
Yes, if you approve it. 3 of the 9 Zenfulfillment tools can create or change data. The other 6 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls (fair use limit: 10,000 tool calls a month), for this Zenfulfillment server only. Cancel any time: Pro then runs to the end of the paid period. Run zenfulfillment_usage_status to see how many calls you used.
Ask the AI to run zenfulfillment_upgrade: it returns a Stripe Checkout link. To cancel, run zenfulfillment_cancel_subscription. Pro continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with zenfulfillment_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.
This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
