Overview

AI-generated overview

Read-only access to a Defontana ERP account: clients, providers, products, stock, sales, purchases, receivables, payables and accounting vouchers.

What you can do
  • Read company, users, clients, client credit and providers
  • Browse products, services, sellers, shops, storages, stock, payment conditions and taxes
  • List and open sales documents, customer orders, purchase documents and purchase orders
  • Inspect the chart of accounts, accounting vouchers and business centers
  • List open receivables and payables per client or provider
  • Check usage, request a feature, upgrade or cancel the subscription
When to use it
Useful when you want an assistant to answer questions about a Chilean company's Defontana records — sales by client and period, unpaid supplier invoices, stock per storage, or voucher details — without exporting data by hand.
Requirements
Remote hosted endpoint; no local install. Sign-in is via OAuth, and on first connect you supply the Defontana client code, company code, and the user and password of a dedicated integration user. A free plan allows 50 tool calls per month; paid plans raise the limit.
Before you install
You hand your Defontana integration credentials to a third-party host, which stores an access token per user. The server includes tools that start a paid Stripe subscription and cancel it, so confirm before any upgrade or cancellation. Data is read-only, but business and accounting records are sent to the host and to your AI client.

Installation

In SourceWeft

  1. Open Defontana MCP by usefulapi in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.usefulapi%2Fdefontana/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

README

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:
json
{  "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.
