Description
Execute arbitrary C# code inside the Unity Editor. The code runs as a method body with access to UnityEngine and UnityEditor namespaces. Use 'return' to send data back. Compiled in-memory — no script files created. Actions: execute (run code), get_history (list past executions), replay (re-run a history entry), clear_history. NOTE: safety_checks blocks known dangerous patterns but is not a full sandbox. Compiler options: 'auto' (Roslyn if available, else CodeDom), 'roslyn' (C# 12+, requires Microsoft.CodeAnalysis), 'codedom' (C# 6 only).
Parameters
| Name | Type | Required | Description |
|---|---|---|---|
action | Literal['execute', 'get_history', 'replay', 'clear_history'] | yes | Action to perform. |
code | str | None | — | C# code to execute (for 'execute' action). Must be a valid method body. Access UnityEngine and UnityEditor namespaces. Use 'return' to send data back. |
safety_checks | bool | — | Enable basic blocked-pattern checks (File.Delete, Process.Start, infinite loops, etc). Not a full sandbox — advanced bypass is possible. Default: true. |
index | int | None | — | History entry index to replay (for 'replay' action). |
limit | int | — | Number of history entries to return (for 'get_history' action, 1-50). Default: 10. |
compiler | Literal['auto', 'roslyn', 'codedom'] | — | Compiler backend for 'execute' action. 'auto' uses Roslyn if Microsoft.CodeAnalysis is installed, else falls back to CodeDom. 'roslyn' forces Roslyn (C# 12+). 'codedom' forces legacy CSharpCodeProvider (C# 6). Default: auto. |
Returns
A dict containing the Unity response. The exact shape depends on the action.
