script-execute

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": "string_value",
  "include": "string_value"
}'

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.
