name	description	metadata
script-execute	Compiles and runs C# in the Unity Editor (Roslyn): plain statements with the last expression as the result, or a full class with a static method. See the skill body for the modes, usings/include and Unity object parameters.	generated-by mcp-plugin-dotnet

Script / Execute

Modes

• Snippet (default): plain statements. The last expression is the result (GameObject.Find("Player").name). Own using lines, local classes and functions are allowed; await works. Usings for System, LINQ, UnityEngine, UnityEditor and AIGD are already there; an unknown type name is imported automatically when exactly one namespace has it.
• Full code: when csharpCode declares class className with a static method methodName, that method runs.
• isMethodBody=true forces snippet mode.

Compile errors point at your own lines (snippet.cs(2,5)).

usings / include

• usings: extra namespaces, e.g. ["MyGame.Gameplay"].
• include: helper .cs files or folders (recursive), relative to <Project>/.ai-game-dev/snippets, compiled with the snippet.

Passing Unity objects as parameters

Parameters become the snippet's variables (or the method's arguments, in order):

• UnityEngine.GameObject — resolves an actual GameObject from value {"instanceID": N}, {"name": "..."}, or {"path": "..."}.
• UnityEngine.Component (or any component subtype) — resolves from {"instanceID": N}.
• AIGD.GameObjectRef — passes a GameObjectRef POCO directly; call goRef.FindGameObject() to resolve it.
• AIGD.ComponentRef — passes a ComponentRef POCO.
• AIGD.ObjectRef — passes a base ObjectRef POCO.

How to Call

unity-mcp-cli run-tool script-execute --input '{
  "csharpCode": "string_value",
  "className": "string_value",
  "methodName": "string_value",
  "parameters": "string_value",
  "isMethodBody": false,
  "usings": [],
  "include": []
}'

For complex input (multi-line strings, code), save the JSON to a file and use:

unity-mcp-cli run-tool script-execute --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool script-execute --input-file - <<'EOF'
{"param": "value"}
EOF

Troubleshooting

If unity-mcp-cli is not found, either install it globally (npm install -g unity-mcp-cli) or use npx unity-mcp-cli instead. Read the /unity-initial-setup skill for detailed installation instructions.

Input

Name	Type	Required	Description
csharpCode	string	Yes	C# code. Snippet: 'var go = GameObject.Find("Player");\ngo.transform.position'. Full: 'public class Script { public static int Main() { return 42; } }'.
className	string	No	Full mode: the class whose static method runs (namespace-qualified or not).
methodName	string	No	Full mode: the static method to run.
parameters	string	No	Values for the snippet's / method's parameters by name, e.g. {go: ref("GameObject#12"), n: 6}. Leave empty if there are none. RQL: SerializedMemberList
isMethodBody	boolean	No	Force snippet mode even when the code declares 'className'.
usings	array	No	Extra namespaces for snippet mode, e.g. ["MyGame.Gameplay"].
include	array	No	Helper .cs files or folders (recursive) compiled with the code, relative to /.ai-game-dev/snippets.
