ShiryuUnityMCP

ShiryuUnityMCP is the Shiryu Studios LLC Unity bridge for the Model Context Protocol (MCP). It lets supported AI clients connect to and automate the Unity Editor for scene work, assets, scripts, testing, builds, and other editor workflows.

Published by Shiryu Studios LLC and distributed through the Shiryu VPM repository.

Install with VCC / ALCOM

Add the Shiryu Studios package repository:

https://packages.shiryu.org/official?download

Then install ShiryuUnityMCP from the package list.

The VPM package ID is:

org.shiryu.unitymcp

Related MCP server: Unity MCP Server

Open the Unity window

Use:

Window > Shiryu Studios > ShiryuUnityMCP

Keyboard shortcut:

  • macOS: Cmd + Shift + M

  • Windows / Linux: Ctrl + Shift + M

Quick start

  1. Open Window > Shiryu Studios > ShiryuUnityMCP.

  2. Run the local setup flow if prompted.

  3. Install Python 3.10+ and uv / uvx if they are missing.

  4. Pick a supported MCP client and configure it from the Client Configuration section.

  5. Start the bridge if it is not already running.

  6. Connect from your MCP client and begin using the Unity tools.

Supported workflow areas

ShiryuUnityMCP includes tooling for:

  • Unity editor and scene automation

  • GameObject and component management

  • Asset and material operations

  • Script creation and validation

  • Build and test automation

  • Screenshots and editor-state inspection

  • MCP client configuration

  • HTTP and stdio transport modes

  • Optional asset-generation integrations

Compatibility

  • Unity 2021.3 or newer

  • Windows, Linux, and macOS

  • VCC / VPM and ALCOM package installation

  • MCP clients supported by the included client configurators

The first Shiryu release is version 1.0.0. The bundled Unity bridge keeps its compatible Python MCP server version separately so ShiryuUnityMCP can follow its own release numbering without breaking server compatibility.

Package migration

The VPM manifest declares the previous com.coplaydev.unity-mcp package as a legacy package and also recognizes the legacy Assets/ShiryuUnityMCP folder. This avoids duplicate assemblies when moving an existing project to the Shiryu VPM package.

Branding and internal compatibility

The public product name is ShiryuUnityMCP and the publisher is Shiryu Studios LLC.

Some internal C# namespaces and assembly names still use MCPForUnity. They are intentionally preserved in the first Shiryu release to avoid breaking serialized references, assembly references, client configuration, and existing integrations. They can be migrated in a future breaking release with explicit compatibility shims.

Publishing the VPM package

For each ShiryuUnityMCP release:

  1. Update the package version and matching release url in package.json.

  2. Create a ZIP whose root contains package.json, Editor, Runtime, LICENSE, README.md, CHANGELOG.md, and THIRD_PARTY_NOTICES.md.

  3. Publish the ZIP as org.shiryu.unitymcp-<version>.zip on the matching GitHub release tag, for example v1.0.0.

  4. Add Shiryu-Studios-LLC/ShiryuUnityMCP to the githubRepos list in the ShiryuVPM listing repository.

  5. Let the VPM listing builder generate the final repository entry, download URL, and ZIP SHA-256.

Published package versions should not be deleted once projects may depend on them.
