What problem does it solve?
It helps you expose a Langium DSL’s real parser and validator as a Model Context Protocol (MCP) tool, so AI assistants can reliably check DSL code and return structured diagnostics instead of guessing.
Core Features & Use Cases
- Generate an MCP server for any Langium DSL: Produces a ready-to-run
validatetool that evaluates in-memory DSL code using your actual Langium services. - Return real diagnostics from parser + validator: Surfaces errors, warnings, hints, and information with line/column context for fast feedback loops.
- Support integration into AI workflows: Enables on-the-fly code validation from MCP-compatible clients such as Claude Code, Cursor, or VS Code while an LLM iterates on generated DSL programs.
Quick Start
Ask the agent to generate an MCP server for your Langium DSL and place it in mcp/, then confirm the output path before file creation.
