UnityNaturalMCP MCP Server

If you want an AI assistant working directly with UnityNaturalMCP, the unitynaturalmcp mcp server is the bridge. UnityNaturalMCP is an MCP server implementation for Unity that aims for a "natural" user experience.

What UnityNaturalMCP does

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

Key capabilities

• 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

Tools it exposes

Once connected, the assistant can call these 11 tools directly:

• 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
• UnityNaturalMCPServer — An MCP server implementation provided as a Unity Package that behaves as a Streamable HTTP server
• UnityNaturalMCPTest — A Unity project for functional verification and as a sample
• Unity — The following packages are required: - UniTask - NugetForUnity
• WSL2 — When using MCP with Claude Code on Windows, you need to use WSL2
• Cursor — Cursor does not support Streamable HTTP as of June 23, 2025. You need to connect via stdio. Please download the latest mcp-stdio-to-streamable-http from
• MCPInspector — From MCP Inspector, you can call MCP tools via Streamable HTTP and perform operational verification

Installing the unitynaturalmcp mcp server

Setup follows the standard MCP pattern: clone or install the server, then register it in your client's configuration file and restart the client. The configuration snippets on this page cover Claude Desktop, Claude Code and Cursor.

Configuration

The server reads 2 environment variables: MCP_SERVER_IP, MCP_SERVER_PORT. Keep credentials in your client's env block or a secrets manager rather than committing them.

Requirements

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

Where it fits

Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. UnityNaturalMCP sits in that group, and the shape of its toolset — RefreshAssets, GetCurrentConsoleLogs, ClearConsoleLogs among others — tells you what it is really for. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

• This server runs locally, so it operates with whatever access your machine and its credentials already have. Scope that deliberately rather than by default.
• With 11 tools exposed, expect a noticeable bump in prompt size — disable it in projects that never use UnityNaturalMCP.
• Maintained by notargs.
• MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the unitynaturalmcp mcp server actually does with your data.
• Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.
