UnityNaturalMCP

日本語

UnityNaturalMCP is an MCP server implementation for Unity that aims for a "natural" user experience.

MCP tools defined in Unity C# can be used directly from MCP clients such as Claude Code, GitHub Copilot(VSCode) and Cursor.

[!WARNING] UnityNaturalMCP is still in the preview stage. It is usable in practice, but several feature additions are planned.

Features

Concise communication flow between Unity Editor and MCP clients
stdio/Streamable HTTP support
Implementation of extended MCP tool entirely written in C# using MCP C# SDK
ClaudeCode, GitHub Copilot(VSCode) and Cursor support

Requirements

Unity 6000.0 or later
Node.js 18.0.0 or later (if using mcp-stdio-to-streamable-http)

Architecture

A[MCP Client] ---|Streamable HTTP| C[UnityNaturalMCPServer]

graph LR
A[MCP Client] ---|stdio| B[stdio-to-streamable-http]
B ---|Streamable HTTP| C[UnityNaturalMCPServer]

UnityNaturalMCPServer

An MCP server implementation provided as a Unity Package that behaves as a Streamable HTTP server.

Clients that support Streamable HTTP, such as Github Copilot(VSCode), can communicate directly with Unity Editor through this server.

mcp-stdio-to-streamable-http

A Node.js-based stdio MCP server that relays communication between MCP clients and Unity.

Some MCP clients, such as Cursor, do not support Streamable HTTP as of June 23, 2025.

By bypassing stdio input to Streamable HTTP, it enables communication between UnityNaturalMCPServer and MCP clients.

UnityNaturalMCPTest

A Unity project for functional verification and as a sample.

MCP Tools

Currently, the following MCP tools are implemented:

RefreshAssets: Refresh Unity Editor assets
GetCurrentConsoleLogs: Get Unity Console log history
ClearConsoleLogs: Clear Unity Console logs
RunEditModeTests: Run Edit Mode tests on Unity Test Runner
RunPlayModeTests: Run Play Mode tests on Unity Test Runner

Installation

Unity

The following packages are required:

Also, install the following Nuget Packages via NugetForUnity:

[!WARNING] ModelContextProtocol is still in preview stage. When installing via NugetForUnity, you need to enable the Show Prerelease toggle.

You can install via UPM (Unity Package Manager):

Edit Packages/manifest.json

Add the following to the dependencies section:

"jp.notargs.unity-natural-mcp": "https://github.com/notargs/UnityNaturalMCP.git?path=/UnityNaturalMCPServer"

Initial Setup

Open Edit > Project Settings > Unity Natural MCP in Unity Editor
Set the MCP server port number (default: 56780)
Click the Refresh button to apply the settings

[!NOTE] 56780 is just the default port. Feel free to change it to
