The Unity side of a workflow built for multiple projects, multiple agents and multiplayer iteration. This UPM package runs the editor bridge used by the companion AnkleBreaker MCP server.

| 338 registered editor routes | Fair scheduling between agents | Multiplayer scenario tools |
|---|---|---|
| Scenes through optional integrations | FIFO per agent, grouped reads | MPPM controls and clone discovery |
The server also provides Hub and connection tools. Route counts describe the checked-in dispatcher; optional integrations require their own packages.
See the workflow
From a prompt to a playable prototype. The recorded neon brick-breaker workflow combines scene authoring, materials, C# gameplay scripts and visual iteration through Unity MCP.

Why this bridge is built for a team of agents
| Need | Plugin behavior | Evidence |
|---|---|---|
| Share an editor fairly | A FIFO queue per agent, round-robin scheduling and grouped reads. | Queue checks |
| Keep projects independent | A listener, queue and identity for each editor; the server pins each request to its target. | Architecture |
| Iterate on multiplayer | Native MPPM scenario/player controls and ParrelSync clone identity. | Host/Client · Clones |
| Inspect and recover | Attributed history, timings, supported Undo and protected ticket retries with an updated server. | Undo · Retry contract |
Installation
