* Add a function to reload the domain Closes #357 * feat: restructure server instructions into workflow-focused format - Reorganized instructions from flat bullet list into categorized workflow sections - Emphasized critical script management workflow with numbered steps - Improved readability and scannability for AI agents using the MCP server It doesn't make sense to repeat the fucnction tools, they're already parsed * docs: reorder tool list alphabetically in README + add reload_domain tool * feat: add Unity editor state and project info resources - Implemented resources for querying active tool, editor state, prefab stage, selection, and open windows - Added project configuration resources for layers and project metadata - Organized new resources into Editor and Project namespaces for better structure * feat: clarify script management workflow in system prompt - Expanded guidance to include scripts created by any tool, not just manage_script - Added "etc" to tools examples for better clarity * refactor: remove reload_domain tool and update script management workflow - Removed reload_domain tool as Unity automatically recompiles scripts when modified - Updated script management instructions to rely on editor_state polling and console checking instead of manual domain reload - Simplified workflow by removing unnecessary manual recompilation step * Change name of menu items resource as the LLM seems it * refactor: reorganize tests into src/tests/integration directory - Moved all test files from root tests/ to MCPForUnity/UnityMcpServer~/src/tests/integration/ for better organization - Added conftest.py with telemetry and dependency stubs to simplify test setup - Removed redundant path manipulation and module loading code from individual test files * feat: expand Unity test workflow triggers - Run tests on all branches instead of only main - Add pull request trigger to catch issues before merge - Maintain path filtering to run only when relevant files change * chore: add GitHub Actions workflow for Python tests - Configured automated testing on push and pull requests using pytest - Set up uv for dependency management and Python 3.10 environment - Added test results artifact upload for debugging failed runs * refactor: update import path for fastmcp Context * docs: update development setup instructions to use uv - Changed installation commands from pip to uv pip for better dependency management - Updated test running instructions to use uv run pytest - Added examples for running integration and unit tests separately * Formatting [skip ci] * refactor: optimize CI workflow with path filters and dependency installation - Added path filters to only trigger tests when Python source or workflow files change - Split dependency installation into sync and dev install steps for better clarity - Fixed YAML indentation for improved readability * Update .github/workflows/python-tests.yml Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> * fix: standardize test mode values to match Unity's naming convention - Changed default mode from "edit" to "EditMode" in C# code - Updated Python tool to use "EditMode" and "PlayMode" instead of lowercase variants * refactor: convert test imports to relative imports - Changed absolute imports to relative imports in integration tests for better package structure - Removed test packages from pyproject.toml package list * refactor: use Field with default_factory for mutable default in TagsResponse * refactor: remove duplicate PrefabStageUtility call * Update this as well [skip ci] * Update MCPForUnity/UnityMcpServer~/src/tests/integration/test_script_tools.py Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> * chore: remove pull_request triggers from test workflows [skip ci] It's already covered by pushes * refactor: update resource function return types to include MCPResponse union * refactor: remove manual domain reload tool - Removed reload_domain tool as Unity handles script recompilation automatically - Updated documentation to reflect automatic compilation workflow - Simplified script management workflow instructions in server description * refactor: add context support to resource handlers - Updated all resource handlers to accept Context parameter for Unity instance routing - Replaced direct async_send_command_with_retry calls with async_send_with_unity_instance wrapper - Added imports for get_unity_instance_from_context and async_send_with_unity_instance helpers * fix: correct grammar in menu items documentation * docs: update README with expanded tools and resources documentation - Added new tools: manage_prefabs, create_script, delete_script, get_sha - Added new resources: editor state, windows, project info, layers, and tags - Clarified manage_script as compatibility router with recommendation to use newer edit tools - Fixed run_test to run_tests for consistency * refactor: convert unity_instances function to async [skip ci] - Changed function signature from synchronous to async - Added await keywords to ctx.info() and ctx.error() calls to properly handle async context methods --------- Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> |

MCP for Unity Server
Model Context Protocol server for Unity Editor integration. Control Unity through natural language using AI assistants like Claude, Cursor, and more.
Maintained by Coplay - This project is not affiliated with Unity Technologies.
💬 Join our community: Discord Server
Required: Install the Unity MCP Plugin to connect Unity Editor with this MCP server.
Installation
Option 1: Using uvx (Recommended)
Run directly from GitHub without installation:
uvx --from git+https://github.com/CoplayDev/unity-mcp@v6.3.0#subdirectory=Server mcp-for-unity
MCP Client Configuration:
{
"mcpServers": {
"UnityMCP": {
"command": "uvx",
"args": [
"--from",
"git+https://github.com/CoplayDev/unity-mcp@v6.3.0#subdirectory=Server",
"mcp-for-unity"
]
}
}
}
Option 2: Using uv (Local Installation)
For local development or custom installations:
# Clone the repository
git clone https://github.com/CoplayDev/unity-mcp.git
cd unity-mcp/Server
# Run with uv
uv run server.py
MCP Client Configuration:
Windows:
{
"mcpServers": {
"UnityMCP": {
"command": "uv",
"args": [
"run",
"--directory",
"C:\\path\\to\\unity-mcp\\Server",
"server.py"
]
}
}
}
macOS/Linux:
{
"mcpServers": {
"UnityMCP": {
"command": "uv",
"args": [
"run",
"--directory",
"/path/to/unity-mcp/Server",
"server.py"
]
}
}
}
Option 3: Using Docker
docker build -t unity-mcp-server .
docker run unity-mcp-server
MCP Client Configuration:
{
"mcpServers": {
"UnityMCP": {
"command": "docker",
"args": ["run", "-i", "unity-mcp-server"]
}
}
}
Configuration
The server connects to Unity Editor automatically when both are running. No additional configuration needed.
Environment Variables:
DISABLE_TELEMETRY=true- Opt out of anonymous usage analyticsLOG_LEVEL=DEBUG- Enable detailed logging (default: INFO)
Example Prompts
Once connected, try these commands in your AI assistant:
- "Create a 3D player controller with WASD movement"
- "Add a rotating cube to the scene with a red material"
- "Create a simple platformer level with obstacles"
- "Generate a shader that creates a holographic effect"
- "List all GameObjects in the current scene"
Documentation
