2026.08 Test Assistant Changelog

AI Assistant Integration

GameDriver MCP Server

• Connects AI assistants like Claude directly to a running Unity or Unreal game — browse the API reference, HierarchyPath syntax, key codes, and console commands, and invoke any GameDriver API call through a single flexible tool.
• Recursively explore an object’s properties, including nested structs and object references, as a browsable tree.
• Parse an exported game-hierarchy file for offline exploration without a live connection.
• Create custom virtual Unity input devices from the MCP tools.
• Claude Desktop can now launch the MCP server directly in the background to access its tools, without opening the Test Assistant UI.
• New command to export the connected game’s live object hierarchy to a file for AI-assisted exploration.

macOS Support

• Native macOS builds (Intel and Apple Silicon) with code signing and notarization. The Standalone Test Assistant did not support macOS before this release; other SDK components already did.

UI Improvements

• Window size, position, and font size are now remembered between sessions.
