joLink Runtime MCP

joLink Runtime is a lightweight, headless Java IDE designed for AI coding agents. It exposes incremental compilation, testing, application startup, and breakpoint debugging via the Model Context Protocol (MCP). This allows agents to run code, inspect real state, and verify changes autonomously without requiring a joLink account, model API key, or separate agent application.
