MPS 2026.1 Has Been Released! - The JetBrains Blog

The MPS 2026.1 release introduces a variety of significant updates and enhancements for developers and language authors. Now built on the IntelliJ Platform 2026.1 with JDK 25 and Kotlin 2.3, this version enhances the Build Language with transitive dependencies and improves reproducibility in migrations. A major highlight is the inclusion of the Projectional Agent Toolkit, which allows AI coding agents to interact directly with MPS models, facilitating advanced development concepts. This toolkit supports AI agents like OpenAI Codex and JetBrains Junie, enabling them to navigate, edit, and generate code within MPS projects. Also notable is the integration of IntelliJ Platform’s natural language support, allowing capitalization checks in specific languages, and the introduction of a new read-only-inspector editor style. The update also refines the project lifecycle management and modernizes migration processes to ensure consistent dependency management. Additionally, users are encouraged to transition to a new UI as the Classic UI plugin is now disabled by default.
