Briox MCP by usefulapi

Briox MCP by usefulapi

Use your Briox account from Claude, Cursor, or any MCP client. Read invoices, customers, suppliers, items, journals, accounts and bank balances, and create customers, items and unposted invoices. Hosted, no local install: connect with your own credentials.

Live endpoint: https://briox.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://briox.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http briox https://briox.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": {
    "briox": {
      "url": "https://briox.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 Briox credentials.

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

On first connect you provide the Country of your Briox account (Sweden or Finland), your Account ID (the long number in parentheses next to your company name) and an Authentication token (Admin → Users → Application Token; Briox registers API developers first). The server validates it and stores it per user. No keys go in config files.
