Check products, stock on hand, customers, orders, invoices and quotes, and create records. Hosted by usefulapi — connect from Claude, ChatGPT, Cursor, or any MCP client.
Team and Enterprise: an Owner adds the connector for the organization first.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"unleashed-software": {
"url": "https://unleashed-software.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"unleashed-software": {
"type": "http",
"url": "https://unleashed-software.usefulapi.io/mcp"
}
}
}No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
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.
The login page asks for your API ID and API Key.
Find both in Unleashed → Integration → Unleashed API Access (API access needs a paid Unleashed subscription). Your API Key is only used to sign requests on your behalf — it is never sent to Unleashed or shown to anyone — and to derive a private account id.
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 API ID and API 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 Unleashed Software connector, then ask in plain words. The AI picks the tools.
| Tool | Type | What it does |
|---|---|---|
unleashed_get_company | read | Get the company Fetch the Unleashed company these credentials belong to — name, base currency and default tax rate. A cheap way to confirm the API id, key and signature are right. Unleashed: GET /Companies. |
unleashed_list_products | read | List products List products, optionally searched by code/description or filtered by code prefix, group, brand, barcode or modification date. Unleashed: GET /Products/{page}. |
unleashed_get_product | read | Get one product Fetch a single product by Guid — prices, units, stock alert levels, group, brand, supplier. Unleashed: GET /Products/{productGuid}. |
unleashed_list_stock_on_hand | read | List stock on hand List stock on hand per product — QtyOnHand, AllocatedQty, AvailableQty, OnPurchase, AvgCost — optionally for one warehouse or as at a past date. Unleashed: GET /StockOnHand/{page}. |
unleashed_get_product_stock | read | Get a product's stock Stock on hand for one product — totals, or broken down per warehouse with allWarehouses=true. The direct answer to 'how many do we have and where?'. Unleashed: GET /StockOnHand/{productGuid}[/AllWarehouses]. |
unleashed_list_customers | read | List customers List customers, optionally filtered by code or name prefix, currency or modification date. Unleashed: GET /Customers/{page}. |
unleashed_get_customer | read | Get one customer Fetch a single customer by Guid — contact details, addresses, currency, payment terms, credit limit. Unleashed: GET /Customers/{customerGuid}. |
unleashed_list_suppliers | read | List suppliers List suppliers, optionally filtered by code prefix, contact email prefix or modification date. Unleashed: GET /Suppliers/{page}. |
unleashed_list_warehouses | read | List warehouses List warehouses (code, name, default flag, address). Warehouse codes are what other tools filter by. Unleashed: GET /Warehouses/{page}. |
unleashed_list_product_groups | read | List product groups List product groups (name, Guid, parent group) — the category tree products are filed under. Unleashed: GET /ProductGroups/{page}. |
unleashed_list_sales_orders | read | List sales orders List sales orders, filtered by status, customer, order number, warehouse or date range. Deleted orders are excluded unless asked for. Unleashed: GET /SalesOrders/{page}. |
unleashed_get_sales_order | read | Get one sales order Fetch a single sales order by Guid, with its lines, totals, customer and warehouse. Unleashed: GET /SalesOrders/{orderGuid}. |
unleashed_list_purchase_orders | read | List purchase orders List purchase orders, filtered by status, supplier, order number, warehouse or date range. Unleashed: GET /PurchaseOrders/{page}. |
unleashed_get_purchase_order | read | Get one purchase order Fetch a single purchase order by Guid, with its lines, supplier and totals. Unleashed: GET /PurchaseOrders/{orderGuid}. |
unleashed_list_invoices | read | List sales invoices List sales invoices, filtered by status, customer, invoice number, sales order number or date range. Unleashed: GET /Invoices/{page}. |
unleashed_list_sales_quotes | read | List sales quotes List sales quotes, filtered by status, customer, quote number or date range. Unleashed: GET /SalesQuotes/{page}. |
unleashed_list_stock_adjustments | read | List stock adjustments List stock adjustments (write-offs, recounts, corrections) with reason, status and lines, filtered by warehouse, product or date. Unleashed: GET /StockAdjustments/{page}. |
unleashed_create_customer | write | Create a customer Create a new customer. CustomerCode must be unique and cannot be changed later. Unleashed: POST /Customers. |
unleashed_create_product | write | Create a product Create a new product. ProductCode must be unique. Unleashed: POST /Products. |
unleashed_create_sales_order | write | Create a parked sales order Create a DRAFT sales order with status Parked (reserves no stock, posts nothing to accounting — a person places or completes it in Unleashed). Line totals, line tax, SubTotal, TaxTotal and Total are computed for you to satisfy Unleashed's validation (SubTotal = sum of line totals, TaxTotal = sum of line taxes, Total = SubTotal + TaxTotal). Unleashed: POST /SalesOrders. |
unleashed_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. | |
unleashed_request_feature | Request a missing feature Tell usefulapi that the user needs something the Unleashed Software 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. | |
unleashed_upgrade | Upgrade to Pro (unlimited*) Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on Unleashed Software (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+, $19/month or $190/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. | |
unleashed_cancel_subscription | Cancel the Pro subscription Cancel the caller's Unleashed Software 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 unleashed_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 Unleashed Software server only. Subscribe with unleashed_upgrade (it returns a Stripe Checkout link). Cancel any time with unleashed_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running unleashed_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 Unleashed Software. The server calls the Unleashed Software API with your own Unleashed Software 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 API ID and API 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 API ID and API 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 Unleashed Software 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 Unleashed Software.
Yes, if you approve it. 3 of the 20 Unleashed Software tools can create or change data. The other 17 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 Unleashed Software server only. Cancel any time: Pro then runs to the end of the paid period. Run unleashed_usage_status to see how many calls you used.
Ask the AI to run unleashed_upgrade: it returns a Stripe Checkout link. To cancel, run unleashed_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 unleashed_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.
