## Summary

The article explains how the Model Context Protocol (MCP), published by Anthropic in November 2024 and later adopted by OpenAI and Google DeepMind, standardises the connection between AI models and business software (accounting, CRM, invoicing). For SMEs without an IT department, this standard promises to reduce integration costs and to let AI agents query several software tools without custom development, for example to monitor cash flow or prepare payment reminders. For business software vendors, MCP raises the question of their role if customers no longer need to open their interface. Some financial software vendors have offered official read-only MCP connectors since November 2025. The article also mentions an episode in which access to a US model was suspended between 12 June and 1 July 2026, which heightened digital sovereignty concerns.
