FunseaAI Unity MCP
Let Claude Code or Cursor drive the Unity Editor through MCP so you can script scenes, assets, and play-mode tasks without leaving chat.
Overview
FunseaAI Unity MCP is a MCP server for the Build phase that stdio-bridges your agent to the local Unity Editor MCP server from FunseaAI/unity-mcp.
What is this MCP server?
- stdio transport bridge to the local FunseaAI Unity MCP server (v0.1.7)
- NuGet package FunseaAI.Unity.Mcp for Unity-side MCP hosting
- Designed for agent-driven Unity Editor workflows on your machine
- GitHub source: FunseaAI/unity-mcp repository
- Server schema version 0.1.7
- Transport: stdio
- Registry package: FunseaAI.Unity.Mcp via nuget
Community signal: 98 GitHub stars.
What problem does it solve?
Agents cannot see or act inside Unity Editor, so game work stalls on manual scene edits and pasted scripts.
Who is it for?
Indie game devs already using Unity who want Claude Code or Cursor to assist with editor-automatable tasks via MCP.
Skip if: Teams without Unity installed or builders who only need generic C# help with no Editor integration.
What do I get? / Deliverables
After you register the stdio bridge, your agent can call Unity MCP tools against your open project on localhost.
- Registered stdio MCP connection to local Unity Editor tools
- Agent-invokable Unity MCP tool surface from your coding assistant

Journey fit
Unity Editor bridging is core product construction for game and interactive 3D stacks, not launch or ops monitoring. It wires your coding agent into the Unity runtime via stdio/NuGet, which is an editor integration rather than pure frontend markup.
How it compares
Unity Editor MCP bridge, not a standalone game engine or asset store.
Common Questions / FAQ
Who is FunseaAI Unity MCP for?
Solo and small-team Unity developers who use MCP-capable agents and want direct Editor tooling from chat.
When should I use FunseaAI Unity MCP?
Use it during Build when you are iterating scenes, scripts, or play-mode checks and want the agent to invoke Unity MCP tools locally.
How do I add FunseaAI Unity MCP to my agent?
Install the NuGet-listed Unity MCP server in your project, run the local Unity MCP host, then add this stdio MCP server entry in Claude Code, Cursor, or another MCP client.
