Bundled engine plugins updated: Unity-MCP 0.92.0, Godot-MCP 0.24.0, Unreal-MCP 0.18.0

Third-party AI agents such as Claude Code, Cursor, VS Code Copilot and Codex connect to your project again without signing in themselves: when you configure an agent from the engine plugin in Cloud mode, it receives a long-lived project key bound to that project, which you can regenerate from the plugin or revoke on ai-game.dev under API Keys, Project keys. Projects on Unity-MCP 0.84 or older should update the plugin to keep Cloud sign-in working.
