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 the custom pricing rules that apply to customer ids or tags, such as b2b. Open one rule by its id to read its discount.

The login page asks for your Store domain (myshopify.com) and Public API access key.
Create the key in the Shopify admin: BSS B2B Solution → Integrations → Public API → Get API key. The Public API needs the Platinum plan. The key is used only to call the API for your store and is never shown to anyone.
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 Store domain (myshopify.com) and Public API access key. 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 BSS B2B Solution connector, then ask in plain words. The AI picks the tools.

|---|---|---|
bssb2b_list_volume_pricing_rules | read | List volume pricing rules List quantity-break (volume) pricing rules for the store, with pagination, sorting and filters.

bssb2b_search_products | read | Search products Search the store's products by text. Returns one page; pass the returned cursor (afterIndex) to fetch the next page. API: POST /api/v1/product/search. |
bssb2b_get_registration_form | read | Get a registration form Get a wholesale registration form definition by its numeric id: fields, labels, types and whether each is required. API: GET /api/v1/rf/form/{id}. |
bssb2b_list_registrations | read | List wholesale registrations List wholesale applicants filtered by status and submission date range. Use status pending to see the accounts waiting for approval. API: POST /api/v1/rf/wholesaler/filter. |
bssb2b_save_custom_pricing_rule | write | Create or update a custom pricing rule Create a custom pricing rule, or update one when `rule.id` is set. Changes live B2B prices in the store. `rule` holds the rule fields (name, priority, status, apply_to, product_condition_type, product_ids, discount_type, discount_value, exc_product_variants, ...). API: POST /api/v1/rule/save. |
bssb2b_delete_custom_pricing_rules | write | Delete custom pricing rules Delete one or more custom pricing rules by id. Deleted rules stop changing store prices at once. API: POST /api/v1/rule/mass-delete. |
bssb2b_set_registration_status | write | Approve or reject wholesale applicants Approve or reject wholesale applicants by email. Only accounts in PENDING status can change; others are not touched. Approval gives the account wholesale prices. API: POST /api/v1/rf/wholesaler/{approve|reject}. |
bssb2b_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. | |
bssb2b_request_feature | Request a missing feature Tell usefulapi that the user needs something the BSS B2B Solution 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. | |
bssb2b_upgrade | Upgrade to Pro (unlimited*) Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on BSS B2B Solution (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. | |
bssb2b_cancel_subscription | Cancel the Pro subscription Cancel the caller's BSS B2B Solution 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 bssb2b_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 user | $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 BSS B2B Solution server only. Subscribe with bssb2b_upgrade (it returns a Stripe Checkout link). Cancel any time with bssb2b_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running bssb2b_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 BSS B2B Solution. The server calls the BSS B2B Solution API with your own BSS B2B Solution 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 Store domain (myshopify.com) and Public API access key. 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 Store domain (myshopify.com) and Public API access key. 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 BSS B2B Solution 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 BSS B2B Solution.
Yes, if you approve it. 3 of the 11 BSS B2B Solution tools can create or change data. The other 8 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 BSS B2B Solution server only. Cancel any time: Pro then runs to the end of the paid period. Run bssb2b_usage_status to see how many calls you used.
Ask the AI to run bssb2b_upgrade: it returns a Stripe Checkout link. To cancel, run bssb2b_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 bssb2b_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.
