Wraps the Just command runner to expose Justfile recipes through MCP's tool interface. Instead of letting your LLM fumble through bash or try to parse Justfiles directly, this gives it four clean tools: list_recipes, run_recipe, get_recipe_info, and validate_justfile. The pitch is solid: Justfiles create a curated, safer command surface than raw shell access, and the recipe abstraction saves context since the LLM gets commands and parameters without reading implementation files. Built in Rust using rmcp, ships as npm/pip/cargo packages plus Docker images. Most useful if you're already using Just for project automation and want to give Claude controlled execution without the hallucination risks of unrestricted bash.
