That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
A Model Context Protocol (MCP) server that exposes the SIBS payment gateway as tools for AI agents — enabling LLMs to create checkouts, verify payments, issue refunds, and generate Multibanco references natively in any MCP-compatible environment.
Bridges the SIBS payment gateway to the MCP ecosystem. Any AI agent or LLM-powered tool running in an MCP-compatible host (Claude Desktop, n8n, custom agents) can:
Check payment status in real time
Create checkout sessions with configurable payment methods
Capture, refund, or cancel authorised payments
Generate Multibanco references for ATM/homebanking payment
Initiate MB WAY push notifications to a customer's phone
