Common questions
Is Gdharness safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.3.90) reached the registry today.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.
What can I use instead?

gdharness
An agent cannot see a running game. It reads your scripts and guesses at the rest: whether the button is on screen, whether the panel updated, whether that error mattered.
gdharness is an MCP server and four Godot addons. Through them the agent asks the open editor and the running game what the screen says and where a control is. It can also ask what a property holds now, what the console printed, and what broke on which line.
Install
Hand this to your agent:
Install gdharness here by following https://aureliolo.github.io/gdharness/agent.md,then tell me what it asked you to recommend back to me.
Or do it yourself, and pick your harness: aureliolo.github.io/gdharness.
The loop it exists for
editor_run { "op": "start", "projectPath": "C:/games/shop" }runtime_inspect { "op": "find", "says": "Buy" } // the button, by the word on it runtime_input { "op": "click", "nodePath": "/root/Shop/Ledger/BuyButton" } runtime_inspect { "op": "text", "nodePath": "/root/Shop/Ledger" } // what the panel says now editor_output { "projectPath": "C:/games/shop" } // errors and warnings, with backtraces
The open editor plays the game, so you can set a breakpoint and read the variables in scope when it stops.
Writes answer with what the engine holds afterwards, never an echo of the request. A tool that cannot answer says which state it is in and what would change it.
