Unity MCP
Drive Unity Editor and Unity runtime from your coding agent via MCP so you can script scenes, iterate on 3D games, and automate editor workflows without clicking through every menu.
Overview
Unity-MCP is an MCP server for the Build phase that links AI agents to the Unity Editor and Unity games through a plugin-backed integration.
What is this MCP server?
- Unity MCP Server packaged as docker.io/ivanmurzakdev/unity-mcp-server:0.17.1 (OCI, stdio transport)
- Unity Editor plugin plus support for MCP-driven workflows in Unity games
- Client → Server ← Plugin link with configurable UNITY_MCP_PORT (default 8080)
- UNITY_MCP_PLUGIN_TIMEOUT and UNITY_MCP_CLIENT_TRANSPORT (stdio or http, default http in env schema)
- Monorepo subfolder Unity-MCP-Server on github.com/IvanMurzak/Unity-MCP
- Catalog/server package version 0.17.1
- Default UNITY_MCP_PORT 8080
- Default UNITY_MCP_PLUGIN_TIMEOUT 10000 ms
What problem does it solve?
Building 3D games in Unity with an agent still means endless manual Editor steps unless something exposes Unity to MCP.
Who is it for?
Indie game devs using Unity who want agent-assisted scene edits, automation, and faster integration loops alongside Claude Code or Cursor.
Skip if: Builders not using Unity, teams wanting zero Docker/local port setup, or non-game SaaS-only stacks.
What do I get? / Deliverables
After you run the Unity MCP server and install the plugin, your agent can drive Unity Editor and game workflows through MCP instead of solo clicking.
- MCP-accessible control path between your agent and Unity Editor/runtime
- Configured Unity MCP server container at catalog version 0.17.1
- Repeatable plugin-to-server connection for game iteration workflows

Journey fit
Unity-MCP is product construction glue—MCP server plus Unity plugin—so it belongs in Build where you integrate engines, agents, and local tooling. It is a deep editor/runtime integration (Docker OCI server, Unity plugin, configurable stdio or HTTP), which maps to integrations rather than generic docs or PM tasks.
How it compares
Unity Editor MCP bridge plus Docker server, not a standalone game engine or generic web automation skill.
Common Questions / FAQ
Who is Unity-MCP for?
Solo builders and small teams making Unity 3D games who want MCP-connected agents to help control the Editor and game project workflows.
When should I use Unity-MCP?
Use it in Build while integrating your agent with Unity—prototyping scenes, automating repetitive editor tasks, or shipping AI-assisted game tooling.
How do I add Unity-MCP to my agent?
Pull docker.io/ivanmurzakdev/unity-mcp-server:0.17.1, set UNITY_MCP_PORT and transport vars as needed, install the Unity plugin from the repo, and register the stdio (or HTTP) MCP server in your agent client.
