AnkleBreaker Unity MCP is a free Unity MCP server from AnkleBreaker Studio with 347 tools.
AnkleBreaker puts 80 tools up front and 269 more behind a proxy. Satura Space gives your agent one, and adds the four features below.
The agent sets up the moment and opens Unity's real Inspector on just the fields that matter. You tune it by feel.
Run agents in parallel, each in its own side Unity project, streamed beside the game. Open a Tuner on any of them.
Up to four synced editors, each streamed with its own input. One handle call starts every player on the same frame.
Ask about anything you don't know. Drift walks you through the UI, points at the field and explains what to tweak in the Inspector.
