Let coding agents play, test and tune your 2D web game. The debuff MCP server attaches to the game you have open (or runs a headless copy) and gives agents live state, explained and source-mapped errors, frame timings, typed params, deterministic replays and rewind, scenario tests and fuzz playtesting. Everything an agent does shows in your dev panel, where you can undo it.

Enables AI assistants to interact with running games in real time — introspecting game state, simulating keyboard and mouse input to actually play, capturing screenshots, executing Lua code, hot-reloading files, and receiving push notifications when state changes.

Give your AI assistant eyes and hands in the Godot editor — and a running game it can actually playtest.

Local-first observability for AI agent stacks. Provides MCP tools for agents to check health, shadow configs, and burnout metrics proactively.
