Read Precoro purchase orders, invoices, suppliers and budgets; approve, reject and submit documents. 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": {
"precoro": {
"url": "https://precoro.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"precoro": {
"type": "http",
"url": "https://precoro.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 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.
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.
Turn on the Precoro connector, then ask in plain words. The AI picks the tools.

precoro_approve_document | write | Approve a document WRITE: 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. POST /{document}/{idn}/approve. |
precoro_reject_document | write | Reject a document WRITE: reject (deny) a document that is waiting for the key user's approval. A comment is required; the creator is notified and sees it. POST /{document}/{idn}/reject. |
precoro_submit_document | write | Submit a draft for approval WRITE: confirm a draft (open) document so it enters the approval flow (or is approved at once if no approval is needed). Approvers are notified. POST /{document}/{idn}/confirm. |
precoro_create_purchase_requisition | write | Create a purchase requisition (draft) WRITE: 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. POST /purchaserequisitions. |
precoro_create_supplier | write | Create a supplier WRITE: 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. POST /suppliers. |
precoro_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. | |
precoro_request_feature | Request a missing feature Tell 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. | |
precoro_upgrade | Upgrade to Pro (unlimited*) Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on Precoro (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. 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. | |
precoro_cancel_subscription | Cancel the Pro subscription Cancel 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. |
| 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 Precoro server only. Subscribe with precoro_upgrade (it returns a Stripe Checkout link). Cancel any time with precoro_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running precoro_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 Precoro. The server calls the Precoro API with your own Precoro 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 Precoro API key, Precoro user email and Region. 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 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.
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.
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.
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 Precoro server only. Cancel any time: Pro then runs to the end of the paid period. Run precoro_usage_status to see how many calls you used.
Ask the AI to run precoro_upgrade: it returns a Stripe Checkout link. To cancel, run precoro_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 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.
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.
