Meet the GameDriver MCP Server

With GameDriver 2026.08, an AI assistant can work with your game while it runs. The new GameDriver MCP Server connects assistants like Claude to a live Unity or Unreal Engine build through GameDriver, so you can ask questions about what is on screen, inspect objects, and write and run tests against the game in front of you.

MCP (the Model Context Protocol) is an open standard for giving AI assistants access to tools. The GameDriver MCP Server is that tool for your game: it gives the assistant the same view of the game that GameDriver's own API has.

What the assistant can do

• Look things up. Browse the GameDriver API reference, HierarchyPath (HPath) syntax, key codes and console commands, so answers and generated code use the real API instead of a guess.
• Explore the running game. Walk the live object hierarchy, resolve HPath queries, and expand an object's properties as a tree, including nested structs and object references.
• Act on the game. Invoke any GameDriver API call through a single tool: click, type, move objects, read values, and check the results.
• Work offline. Export the connected game's object hierarchy to a file, and let the assistant explore it later without a live connection.
• Set up input. Create custom virtual Unity input devices directly from the MCP tools.

Where it helps

The slow part of writing a game test is rarely the test logic. It is finding the right object, working out a HierarchyPath that will hold up across builds, and checking which property actually changes when the player does something. With the MCP Server, you can ask the assistant to do that discovery against the running game and draft the test from what it finds, then review it and run it.

It also helps when you are new to GameDriver. Instead of switching between the API docs and the game, you can ask how to do something and get an answer grounded in the game you are testing.

The assistant works for the person driving it. Your team still decides what to test, judges the results and makes the release calls.

Unity and Unreal

The MCP Server supports both engines. On Unreal, the assistant can browse a live Unreal object hierarchy, resolve HPath queries, and author and run tests against a connected game. Values come back with their correct types rather than as plain strings, which keeps generated assertions accurate.

Getting started

The MCP Server ships with the standalone Test Assistant in 2026.08. Claude Desktop can start it in the background, so you don't need the Test Assistant UI open to use it. The MCP configuration guide walks through setup on Windows and macOS, and the rest of the release is covered in the GameDriver 2026.08 release post.
