SmartBill MCP by usefulapi

SmartBill MCP by usefulapi

Use SmartBill from Claude, Cursor, or any MCP client — document series, VAT rates, stock, payment status, clients, suppliers, products and warehouses, plus invoices and estimates (drafts by default), storno, cancel/restore, payments and sending documents by e-mail. Hosted, no local install: connect with your own SmartBill credentials.

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

Connect

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