Junius is a Windows local-execution service that exposes workspace files, processes, background jobs, Git, browser automation and desktop interaction to an MCP-connected assistant. It separates the assistant’s decisions from local execution and includes access to agent skills. The repository documents installation, architecture and the boundaries of its local runtime.
