STEL Order MCP by usefulapi

STEL Order MCP by usefulapi

Use your STEL Order account from Claude, Cursor, or any MCP client. It reads clients, products, sales documents, invoices, invoice receipts and stock, and it creates or updates clients and creates contacts. Hosted, no local install: connect with your own credentials.

Live endpoint: https://stel-order.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://stel-order.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http stel-order https://stel-order.usefulapi.io/mcp, then run /mcp to log in.
• VS Code: Add to VS Code.
• Cursor and other clients: add the URL as a remote MCP server:

{
  "mcpServers": {
    "stel-order": {
      "url": "https://stel-order.usefulapi.io/mcp"
    }
  }
}

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, and the login page asks for your STEL Order credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/stel-order/

On first connect you provide your STEL Order APIKEY. Find it in STEL Order under Functionalities → API, using a superadmin account. The server validates the key and stores it per user. No keys go in config files.
