unity-skill-create
Create a new skill using C# code. It will be added into the project as a .cs file and compiled by Unity. The skill will be available for use after compilation.
It must be a partial class decorated with [McpPluginToolType]. Each tool method must be decorated with [McpPluginTool]. The class name should match the file name. All Unity API calls must use com.IvanMurzak.ReflectorNet.Utils.MainThread.Instance.Run(). Return a data model for structured output, or void for side-effect-only operations.
Full sample:
```csharp
#nullable enable
using System;
using System.ComponentModel;
using com.IvanMurzak.McpPlugin;
using com.IvanMurzak.ReflectorNet.Utils;
using com.IvanMurzak.Unity.MCP.Editor.Utils;
using com.IvanMurzak.Unity.MCP.Runtime.Data;
using UnityEditor;
using UnityEngine;
namespace com.IvanMurzak.Unity.MCP.Editor.API
{
[McpPluginToolType]
public partial class Tool_Sample
{
[McpPluginTool("sample-get", Title = "Sample / Get")]
[Description("Finds a GameObject and returns its ref data.")]
public GameObjectRef Get
(
[Description("Name of the GameObject to find.")]
string name
)
{
return MainThread.Instance.Run(() =>
{
var go = GameObject.Find(name)
?? throw new ArgumentException($"GameObject '{name}' not found.", nameof(name));
return new GameObjectRef(go);
});
}
[McpPluginTool("sample-rename", Title = "Sample / Rename")]
[Description("Renames a GameObject.")]
public void Rename
(
[Description("Current name of the GameObject.")]
string name,
[Description("New name to assign.")]
string newName
)
{
MainThread.Instance.Run(() =>
{
var go = GameObject.Find(name)
?? throw new ArgumentException($"GameObject '{name}' not found.", nameof(name));
go.name = newName;
EditorUtility.SetDirty(go);
AssetDatabase.Refresh(ImportAssetOptions.ForceSynchronousImport);
EditorUtils.RepaintAllEditorWindows();
});
}
}
}
```
## Suggestions
### Refresh UI after visual changes
If the skill modifies anything visually in the Unity Editor (GameObjects, components, materials, etc.), call these two lines at the end of the tool method to apply changes to the UI immediately:
```csharp
AssetDatabase.Refresh(ImportAssetOptions.ForceSynchronousImport);
EditorUtils.RepaintAllEditorWindows();
```
### Refresh AssetDatabase after asset or script changes
If the skill creates, modifies, or deletes any asset file or .cs script on disk outside of Unity API, call this inside a `MainThread.Instance.Run()` block to ensure Unity picks up the changes:
```csharp
MainThread.Instance.Run(() =>
{
AssetDatabase.Refresh(ImportAssetOptions.ForceSynchronousImport);
});
```
### Use processing mechanic for long-running or domain-reload operations
Some operations take time to complete and may trigger a Unity domain reload (e.g. writing a .cs script, switching play mode, running tests, adding a package). In these cases the tool must NOT block and wait — instead it must:
1. Accept a `[RequestID] string? requestId` parameter.
2. Return `ResponseCallTool.Processing("...").SetRequestID(requestId)` immediately.
3. Schedule the actual work asynchronously via `MainThread.Instance.RunAsync(async () => { await Task.Yield(); ... })`.
4. When the operation finishes, send the final result by calling:
```csharp
_ = UnityMcpPluginEditor.NotifyToolRequestCompleted(new RequestToolCompletedData
{
RequestId = requestId,
Result = ResponseCallTool.Success("Operation completed.").SetRequestID(requestId)
});
```
If the operation may survive a domain reload (e.g. a .cs file was saved and Unity will recompile), use `ScriptUtils.SchedulePostCompilationNotification(requestId, filePath, operationType)` instead of calling `NotifyToolRequestCompleted` directly — it persists the pending notification to `SessionState` and sends it automatically after the domain reload completes. For package install/removal or other non-compilation domain reloads use `PackageUtils.SchedulePostDomainReloadNotification(requestId, label, action, expectedResult)` the same way.
### Return structured data with a typed response
Prefer returning a structured data model over a plain string so the AI can parse individual fields. Declare a nested class with `[Description]` on each property and use `ResponseCallValueTool<T>` as return type:
```csharp
// Return type:
public ResponseCallValueTool<MyResult> MyTool(...)
{
return ResponseCallValueTool<MyResult>.Success(new MyResult
{
Name = go.name,
InstanceID = go.GetInstanceID()
}).SetRequestID(requestId);
}
// Data model:
public class MyResult
{
[Description("Name of the GameObject.")]
public string? Name { get; set; }
[Description("Unity instance ID of the GameObject.")]
public int InstanceID { get; set; }
}
```
For simpler cases that do not need async/processing, you may return the model directly (without `ResponseCallValueTool<T>`) and Unity-MCP will wrap it automatically.
### Validate inputs early and throw clearly
Always validate required parameters at the top of the method before any Unity API calls. Throw `ArgumentException` or `InvalidOperationException` with descriptive messages so the AI knows exactly what went wrong and can self-correct:
```csharp
if (string.IsNullOrEmpty(name))
throw new ArgumentException("Name cannot be null or empty.", nameof(name));
```
### Always use MainThread for Unity API calls
All Unity API calls (including `GameObject.Find`, `AssetDatabase`, `EditorUtility`, etc.) MUST run on the main thread. Wrap them in `MainThread.Instance.Run(() => { ... })` for synchronous operations, or `MainThread.Instance.RunAsync(async () => { ... })` when you need to await inside.

-
assets-find
Search the asset database using the search filter string. Allows you to search for Assets. The string argument can provide names, labels or types (classnames).
IvanMurzak/Unity-MCP 2,087
-
script-read
Reads the content of a script file and returns it as a string. Use 'script-update-or-create' tool to update or create script files.
IvanMurzak/Unity-MCP 2,087
-
assets-delete
Delete the assets at paths from the project. Does AssetDatabase.Refresh() at the end. Use 'assets-find' tool to find assets before deleting.
IvanMurzak/Unity-MCP 2,087
-
tests-run
Execute Unity tests and return detailed results. Supports filtering by test mode, assembly, namespace, class, and method. Recommended to use 'EditMode' for faster iteration during development.

-
assets-create-folder
Creates a new folder in the specified parent folder. The parent folder string must start with the 'Assets' folder, and all folders within the parent folder string must already exist. For example, when specifying 'Assets/ParentFolder1/ParentFolder2/', the new folder will be created in 'ParentFolder2' only if ParentFolder1 and ParentFolder2 already exist. Use it to organize scripts and assets in the project. Does AssetDatabase.Refresh() at the end. Returns the GUID of the newly created folder, if successful.

office-hours
MANUAL TRIGGER ONLY: invoke only when user types /office-hours. YC Office Hours — two modes. Startup mode: six forcing questions that expose demand reality, status quo, desperate specificity, narrowest wedge, observation, and future-fit. Builder mode: design thinking brainstorming for side projects, hackathons, learning, and open source. Saves a design doc. Use when asked to "brainstorm this", "I have an idea", "help me think through this", "office hours", or "is this worth building". Proactively suggest when the user describes a new product idea or is exploring whether something is worth building — before any code is written.
