Beckett - MCP for Godot MCP server

Beckett — MCP for Godot

Stop waiting for Godot.

Beckett is a zero-sidecar Model Context Protocol (MCP) server embedded directly in the Godot 4 editor as a GDScript EditorPlugin. AI agents (Claude and others) drive the editor over HTTP — no Node/Python bridge, no second process, no cloud.

This repository is the free, MIT-licensed Lite edition: the complete inspect → author → run → SEE dev loop (55 tools), for GDScript and C#. The AI can now watch your running game on the free tier: screenshot it, read the live remote scene tree and node state, poll performance monitors, and tail the game's logs. The paid Full edition makes the AI the playtester (it drives input, clicks 2D/3D and UI, and asserts the results), plus a test runner, animation tools, scatter_nodes, background exports, project-wide analysis, and 46 knowledge packs. See What Full adds.

Lite: the AI sees your game. Full: the AI playtests it.

Demo

Why

Existing Godot MCP servers either shell out to the CLI (can't play the game, screenshot, or inspect runtime) or run a Node/Python sidecar that relays to a thin in-editor addon. This one makes the addon itself the MCP server, and exposes reflection-generic tools that work on any class via ClassDB — instead of hundreds of hand-coded per-domain wrappers (an anti-pattern: LLMs degrade past ~40 tools).
