Added

  • scriptable_get: read a named serialized field from a ScriptableObject asset by path
  • scriptable_set: write a named serialized field on a ScriptableObject asset and save it to disk

Changed

  • screenshot no longer returns base64 image data inline. It saves to a PNG file and returns the absolute path. Use max_size to downscale before saving.
  • execute_script now loads compiled assemblies into a collectible AssemblyLoadContext so they are garbage-collected after each call, preventing domain reload slowdown over time.
  • set_project now calls list_commands immediately after setting the project path, so Unity commands are available without a separate discovery step. The response includes commands_loaded on success or a warning if Unity is not reachable.
  • open_project and create_project now return a choose_unity_version response listing all detected installs when multiple Unity versions are installed and unity_path was not specified. Re-call with unity_path set to the desired entry.
  • help (no argument) always returns at least the Go-side commands (set_project, open_project, create_project, find_unity_installs) and includes a _warning with instructions to call set_project when Unity commands have not been loaded yet.

Removed

  • invoke tool removed from the MCP server. All Unity commands are now registered as discrete named tools at startup. LLMs can no longer route arbitrary command names through a generic escape hatch.
  • IAgentCommand.Core property removed. All registered commands are now exposed as named MCP tools; there is no longer a distinction between core and non-core commands.
