usefulapiUnleashed Software MCP server
Check products, stock on hand, customers, orders, invoices and quotes, and create records. Hosted by usefulapi: connect it to Claude, ChatGPT, Cursor or any MCP client.
What can I ask?
Turn on the Unleashed Software connector, then ask in plain words. The AI picks the tools.
- How much stock do we have on hand of each product in the main warehouse?
- Which sales orders are still open for Acme Ltd?
- List the purchase orders placed with suppliers in the last 30 days.
- Show invoices raised this month with their totals.
What you can do with Unleashed Software in Claude and ChatGPT
For inventory and operations teams who run stock and orders in Unleashed Software.
Check stock on hand by product and warehouse
The AI reads quantity on hand, allocated and available, per product, for one warehouse or all, or as at a past date.
Review open sales orders for a customer
The AI lists sales orders by status, customer or date range and opens one with its lines and totals.
Review purchase orders placed with suppliers
The AI lists purchase orders by status, supplier or date range, and opens one with its lines and totals.
Check invoices, quotes and stock adjustments
The AI lists sales invoices and quotes by status, customer or date range, and stock adjustments (write-offs, recounts) by warehouse, product or date.
Add a customer, a product or a draft sales order
The AI creates a customer or a product, or a sales order in Parked status. A parked order reserves no stock and posts nothing to accounting.
Changes dataHow do I connect Unleashed Software?
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.

Claude Code
Run this command, then run /mcp in Claude Code to log in:
Cursor
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"unleashed-software": {
"url": "https://unleashed-software.usefulapi.io/mcp"
}
}
} VS Code
Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"unleashed-software": {
"type": "http",
"url": "https://unleashed-software.usefulapi.io/mcp"
}
}
} Codex
Run these commands. The second one opens the login page:
Other clients
Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.
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.
Pricing
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper user | $9/mo · $90/yr | 10,000 tool calls / month |
| Pro+per user | $39/mo · $390/yr | 100,000 tool calls / month |
Each paid plan covers this Unleashed Software server only. Ask your AI to run unleashed_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with unleashed_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with unleashed_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Your usefulapi plan · 4
- Usage status (free-tier meter)
unleashed_usage_statusReport 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. - Request a missing feature
unleashed_request_featureTell 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. - Upgrade to Pro or Pro+
unleashed_upgradeGet a paid plan for Unleashed Software (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter. - Cancel the Pro subscription
unleashed_cancel_subscriptionCancel 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.
FAQ
What can I do with Unleashed Software in Claude or ChatGPT?
Check stock on hand by product and warehouse. Review open sales orders for a customer. Review purchase orders placed with suppliers. Check invoices, quotes and stock adjustments. Add a customer, a product or a draft sales order. See what you can do for the details.
Is this an official Unleashed Software product?
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.
Can I connect Unleashed Software to Claude or ChatGPT?
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.
What do I need to connect?
The login page asks for your API ID and API Key. See Before you connect for where to find them.
Do I put my Unleashed Software key or an Authorization header in the client config?
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.
How do you keep my Unleashed Software credentials?
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.
Can the AI change my Unleashed Software data?
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.
What does it cost?
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this Unleashed Software server only. Cancel any time: your paid plan then runs to the end of the paid period. Run unleashed_usage_status to see how many calls you used.
How do I subscribe or cancel?
Ask the AI to run unleashed_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run unleashed_cancel_subscription. Your paid plan continues to the end of the paid period.
What if a Unleashed Software tool that I need is missing?
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.
Which AI clients can I use?
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.
