We probably never want to rename props as it causes major migration issues 🙈 At least till we have a migration API for renaming.

I think we can modify and keep it as a guardrail, this can trigger a "Don't do it" logic we would like to provide.
That guardrail can also be added into PRD, but doesn't an mcp level intervention sound safer? It is indeed a critical knowledge not to rename properties.

I think we can benefit from some kind of library that converts properties xml to some sort of json structure/AST and back. Co we can manipulate this simpler tree instead of doing magic on the pure XML tree. I believe @iobuhov already has this as he was experimenting with moving properties between XML and YAML formats.

There are already utils for this in automation/utils, better to re-use those ones if we can.

Major enhancements to the MCP server for better AI assistance: Sampling API (Context Awareness): - Lets AI "preview" widget code before making changes - Provides overview, properties, and runtime samples via Resources API - Think: "Look under the hood before fixing" Prompts API (Guided Workflows): - 7 pre-built "recipes" for common tasks (add property, build, debug, etc.) - Step-by-step guidance prevents AI mistakes - Think: "IKEA instructions for widget development" Architecture Improvements: - Modular structure: sampling.ts, prompts.ts separate from helpers.ts - Better separation of concerns - Cleaner, more maintainable codebase Documentation: - Updated README with clear explanations - Added usage examples for new features - Included project structure overview These changes make the AI smarter and less likely to break widgets by providing context awareness and structured workflows.

MVP: Mendix Pluggable Widget Generator MCP Server
Introduces an MVP MCP (Model Context Protocol) server for widget generation and editing in the web-widgets monorepo. The primary goal is to enable AI-assisted widget creation and modification, with the ability to generate MPK files ready for deployment.
MVP Goals
Core Functionality:
npx generator-widgetintegrationHost Examples:
claude_desktop_config.json.cursor/mcp.jsonAdditional Features (Being implemented)
While the MVP focuses on generation and MPK export, the following capabilities are also implemented:
Discovery & Inspection:
Build & Testing:
Change Management:
Safety:
Architecture
Modular Tool System:
pluggable-widget-toolsfor type generationMCP Resources:
MVP Status
Core widget generation/edit tools
MPK export functionality
MCP server infrastructure
Safety guardrails
Additional features (working, may need refinement)
This MVP establishes the foundation for AI-assisted widget development, with the primary goal of generating deployable MPK files from widget source code.
It's a WIP.
