Defontana MCP by usefulapi

Use your Defontana account from Claude, Cursor, or any MCP client. Read clients, providers, products, stock, sales, purchases, receivables, payables and accounting vouchers, all read-only. Hosted, no local install: connect with your own credentials.

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

Connect

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

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

On first connect you provide your client code and company code (both assigned by Defontana), and the user and password of a dedicated integration user. The server validates it and stores only the access token per user. No keys go in config files.
