Unity CLI and Unity Pipeline

Unity introduced the Unity CLI, a standalone terminal binary that manages editors, projects, auth, and CI with structured JSON and TSV output, no UI required. The piece that matters for small teams is MCP Mode: existing MCP agents like Claude Code, Cursor, and Copilot can drive a Unity project from the terminal without a rewrite, and both the CLI and MCP are free with no concurrency limits. A companion experimental package, Unity Pipeline, lets the CLI talk to a running editor or dev build over a local API so an agent can make changes and test them live. Pipeline is flagged experimental, so expect rough edges when it drives the editor. It is the official on-ramp for the agentic Unity workflow people have been wiring together by hand.
