Which integrations are available for this server?

Controls the Unity Editor by providing tools for scene management, GameObject manipulation, asset operations, script handling, and more, allowing AI agents to interact with Unity directly.

Patina

npm version MCP Registry Glama MCP server License: MIT

Control the Unity Editor from any MCP host. One package install, one click, and your AI assistant can see your scene, create objects, and talk to the console.

Patina is a Rust MCP server paired with a C# Unity bridge. It connects your favorite AI coding tool directly to the Unity Editor over a local TCP channel, with zero manual config.

Why Patina?

One-click setup. Install the UPM package, click a button, and every supported host is configured automatically.
No Rust required. Release packages ship pre-built binaries for Windows, Linux, and macOS. Just install and go.
Built for speed. The Rust sidecar keeps the MCP layer fast and lightweight while Unity stays on the main thread.
Multi-host. Works with Claude Code, Cursor, VS Code, Gemini CLI, JetBrains Rider, Codex CLI, and more.

How It Works

MCP Host  <-- stdio -->  Patina Server  <-- local TCP -->  Unity Editor

The host launches the Rust binary over stdio MCP. The Rust server forwards tool calls into Unity through a local loopback TCP bridge. Unity executes them on the main thread and returns the result.

Quick Start

1. Install the Unity package

In Unity, open Project Settings > Package Manager, add a scoped registry, then install the package by name.

Scoped registry:

Field	Value
Name	`npmjs`
URL	`https://registry.npmjs.org`
Scope(s)	`com.taygunsavas`

Then open the Package Manager (Window > Package Manager), click the + icon in the top left, select Add package by name..., and enter:

com.taygunsavas.patina-unity-mcp

Alternatively, open the Package Manager, click the + icon, select Add package from git URL..., and enter:

https://github.com/taygunsavas/patina-unity-mcp.git?path=/unity-package

Patina is distributed as a complete Unity package artifact with the editor code, native Rust runtime binaries under Plugins/<platform>/, and the Unity metadata needed for import. End users do not need the Rust toolchain or a Git checkout of this repository.

2. Run One-Click Setup

Open Window > Patina Unity MCP and click One-Click Setup.

The setup flow verifies the binary, starts the Unity bridge, auto-configures every detected host, replaces stale entries, and shows restart guidance where needed.

3. Start building

Open your MCP host and try:

"Log hello to Unity console"
"Show me the scene hierarchy"
"Create a cube at position 0, 2, 0"

Local Development

Contributor source checkout

Use this when you are editing unity-package/ or rust-server/ directly from the repository:

Point Unity at the local package checkout.
- file:<your-clone-path>/unity-package
Build the Rust server.

cd rust-server && cargo build --release

Publish the current binary into the local development runtime path.

pwsh -File scripts/publish-dev-runtime.ps1

In Unity, open Window > Patina Unity MCP, enable Use Local Runtime (Contributor), and click One-Click Setup.

This writes host configs against the local dev runtime instead of the packaged binary. Re-run One-Click Setup after every new cargo build --release + publish-dev-runtime pass, and use Remove Patina From Hosts before switching back to the packaged flow.

Stage a local UPM test package

Use this when you want to test the package as it will be published, not the raw source checkout:

pwsh -File scripts/stage-local-upm.ps1

Then add the staged package from disk in Unity:

dist/local-upm/com.taygunsavas.patina-unity-mcp/package.json

Prefer the staged local package when you are validating package layout, import behavior, or release packaging. Prefer the source checkout path when you are actively editing source and want the fastest edit-build-run loop.

See CONTRIBUTING.md for the full contributor workflow.

Community and Contributing

Start with CONTRIBUTING.md for the local development loop, validation expectations, and pull request guidance.
Use GitHub issue forms for reproducible bugs, feature proposals, and usage questions so maintainers get the context they need.
Read .github/SUPPORT.md before opening a help request.
Read .github/SECURITY.md for private vulnerability reporting.
Read .github/CODE_OF_CONDUCT.md before participating in issues and pull requests.
Pull requests targeting main are expected to pass CI and go through CODEOWNERS + Copilot review once repository rules are enabled.

Requirements

Unity 6 (6000.3 LTS+)
