usefulapiPrecoro MCP server
Read Precoro purchase orders, invoices, suppliers and budgets; approve, reject and submit documents. Hosted by usefulapi: connect it to Claude, ChatGPT, Cursor or any MCP client.
What can I ask?
Turn on the Precoro connector, then ask in plain words. The AI picks the tools.
- Which purchase orders are waiting for my approval, and what do they total?
- List the unpaid supplier invoices from the last 30 days.
- How much of each budget have we spent so far this quarter?
- Create a draft purchase requisition for 20 office chairs at 150 USD for the Head Office.
What you can do with Precoro in Claude and ChatGPT
For procurement and finance teams who buy through purchase orders in Precoro.
Find purchase orders waiting for your approval
The AI lists purchase orders filtered by status or those waiting for your approval, with supplier, totals and payment status, and reads one with its items.
List unpaid supplier invoices
The AI lists supplier invoices and credit notes with due date, paid sum and payment status, and reads one with its matching to orders and payments.
Check how much of each budget is spent
The AI lists budgets with period, total sum and how much is used in requisitions, purchase orders, invoices and expenses.
Approve or reject documents waiting for you
The AI finds documents waiting for your approval, then approves one or rejects it with a comment. Approving can release spending and cannot be undone here.
Changes dataCreate a draft purchase requisition and submit it
The AI creates a draft requisition with location, currency, delivery date and items, and submits it for approval when you say so.
Changes dataLook up suppliers or add a new one
The AI lists suppliers with payment conditions and contacts, reads one supplier, and creates a new supplier with a unique name.
Changes dataHow do I connect Precoro?
Before you connect
The login page asks for your Precoro API key, Precoro user email and Region.
In Precoro open Configuration → Integrations → API Key and press Generate API Key (it is shown only once). The key belongs to one user and one company, and the connection sees only what that user may see; a dedicated user with the roles you want to share makes its activity easy to track. Choose the region of your Precoro address: app.precoro.com is International, app.precoro.us is United States. Your key is used only to call the Precoro API on your behalf; it is never shown to anyone.

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": {
"precoro": {
"url": "https://precoro.usefulapi.io/mcp"
}
}
} VS Code
Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"precoro": {
"type": "http",
"url": "https://precoro.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 Precoro API key, Precoro user email and Region. 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 Precoro server only. Ask your AI to run precoro_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 precoro_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 precoro_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

- Approve a document
precoro_approve_documentWRITE: approve a document as the Precoro user the API key belongs to (that user must be a current approver of it). Approving can release spending: an approved purchase order may be sent to the supplier and an approved invoice can go to payment. Find candidates with the list tools and waiting_for_my_approval. Cannot be undone through this server. - Reject a document
precoro_reject_documentWRITE: reject (deny) a document that is waiting for the key user's approval. A comment is required; the creator is notified and sees it. - Submit a draft for approval
precoro_submit_documentWRITE: confirm a draft (open) document so it enters the approval flow (or is approved at once if no approval is needed). Approvers are notified. - Create a purchase requisition (draft)
precoro_create_purchase_requisitionWRITE: create a purchase requisition in draft (open) status for the key user; it is not submitted for approval until precoro_submit_document is called. Needs a location id, a currency, a delivery date and at least one item (a catalog item_id, or a name with quantity and price). Find ids with precoro_list_reference_data (locations, legal_entities, document_custom_fields) and precoro_list_items. All required document custom fields (for example department or project) must be passed in custom_fields. Returns the new idn and id. - Create a supplier
precoro_create_supplierWRITE: create a supplier. The name must be unique in the company (a duplicate name, unique code or registration number is rejected). The supplier is available to all legal entities. Depending on the company's settings it may need approval before it can be used on orders. Returns the new supplier.
Your usefulapi plan · 4
- Usage status (free-tier meter)
precoro_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
precoro_request_featureTell usefulapi that the user needs something the Precoro 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+
precoro_upgradeGet a paid plan for Precoro (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
precoro_cancel_subscriptionCancel the caller's Precoro 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 precoro_upgrade later to undo the cancel before the period ends. Does not count against the meter.
FAQ
What can I do with Precoro in Claude or ChatGPT?
Find purchase orders waiting for your approval. List unpaid supplier invoices. Check how much of each budget is spent. Approve or reject documents waiting for you. Create a draft purchase requisition and submit it. Look up suppliers or add a new one. See what you can do for the details.
Is this an official Precoro product?
No. usefulapi is an independent service. It is not affiliated with or endorsed by Precoro. The server calls the Precoro API with your own Precoro access, so it sees only the data that your account can see.
Can I connect Precoro 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 Precoro API key, Precoro user email and Region. See Before you connect for where to find them.
Do I put my Precoro 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 Precoro API key, Precoro user email and Region. 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 Precoro credentials?
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Precoro 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 Precoro.
Can the AI change my Precoro data?
Yes, if you approve it. 5 of the 24 Precoro tools can create or change data. The other 19 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 Precoro server only. Cancel any time: your paid plan then runs to the end of the paid period. Run precoro_usage_status to see how many calls you used.
How do I subscribe or cancel?
Ask the AI to run precoro_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 precoro_cancel_subscription. Your paid plan continues to the end of the paid period.
What if a Precoro tool that I need is missing?
Tell the AI what you wanted to do. It can send the request with precoro_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.
