As we talk to Mendix customers and partners every day, the excitement surrounding the upcoming Mendix 11.12 lts (long-term support) release is undeniable. Mendix 11 isn’t just an incremental update; it officially ushers in what we at Menditect see as the “agentic era” of low-code development. Deeply integrated AI capabilities like MAIA (Mendix AI assistant) for automated app bootstrapping, MAIA for workflows, MAIA for oql, and the Mendix agents kit allow enterprises to build, iterate, and deploy hyper-intelligent, data-driven applications faster than ever.
Yet, for many IT managers, product owners, and development teams currently running core business applications on Mendix 9 or 10, a massive roadblock stands between them and these AI-driven benefits.
That roadblock is the migration itself. More specifically: the nightmare of legacy regression testing.
While Mendix 11 clients get AI-driven test acceleration natively with MAIA out of the box, we at Menditect have delivered a solution specifically designed to bridge the gap for Mendix 9 and 10 users to help them solve the Mendix 11 migration bottleneck.
By harnessing the open-source model context protocol (MCP), Menditect allows you to automatically generate a robust test safety net for your legacy applications 6x to 10x faster than traditional methods, at a fraction of the historical cost and at incredibly low token usage.
Our solution for Mendix 9/10 applications functions seamlessly through three main components:

The LLM connects via MCP to Menditect, leveraging the built-in commands of mxcli to safely extract model information and automatically design comprehensive regression tests. Once the LLM designs the tests, they are pushed directly into Menditect test automation (mta), which automatically generates and handles execution across all levels—from microflow unit tests and apis to full end-to-end user flows.
This setup isn’t just a theoretical breakthrough; it provides practical, concrete benefits that satisfy everyone from executive leadership to the engineering team.
Don’t let the fear of regression testing keep your organization stuck on older software versions. By utilizing Menditect with MCP, you can eliminate the testing bottleneck, protect your application lifecycle, and establish a faster, cheaper path to the massive business advantages of Mendix 11.
