godot-mcp

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

Why this one?

There are a few Godot MCP servers out there, and most can open a scene and poke at nodes. This one is built around a harder problem: letting an agent verify its own work. Run the game, drive it like a player, observe what actually happened, and prove the change did what it claimed — without you ferrying screenshots and error logs back and forth.

The pieces that make that possible, and that you won't find elsewhere:

• Deterministic playtesting. Freeze the game clock, step exact slices of game time (or step until a condition holds), with inputs riding inside the window. Observation never races the game.
• Cheap observation. Live entity state — positions, velocities, animation state, your own custom data — as structured JSON. Most "what's happening on screen?" questions get answered without spending vision tokens on a screenshot.
• Real input. Named actions with analog strength, joypad buttons and stick vectors, raw keys with modifier combos, relative mouse-look, text typing. Sequences run with precise timing and can prove they changed game state.
• Scenario setup. Run GDScript inside the running game: grant the weapon, skip to wave 3, spawn a test bot — no debug hooks baked into your game code.

Here's what that looks like when an agent tests a boss fight:

godot_editor_edit   run frozen=true           # boot with game time frozen at frame 0
godot_exec          GameState.wave = 3        # set up the scenario worth testing
godot_game_time     step_until "tree.get_nodes_in_group('boss').size() >= 1"
godot_runtime_state digest                    # exact positions and state — no pixels, no guessing
godot_game_time     step 500ms + dodge input  # play the moment that matters
godot_editor_read   screenshot_game           # and a screenshot when it's actually worth the tokens

Less copy-paste, more creating.

Quick Start

1. Configure your AI assistant

Add godot-mcp to your MCP client. See the Installation Guide for config examples (Claude Desktop, Claude Code, VSCode/Copilot, and more). The short version:

{
  "mcpServers": {
    "godot-mcp": {
      "command": "npx",
      "args": ["-y", "@satelliteoflove/godot-mcp"]
    }
  }
}

2. Install the Godot addon

npx @satelliteoflove/godot-mcp --install-addon /path/to/your/godot/project

Enable it in Godot: Project > Project Settings > Plugins > Godot MCP

3. Start building

Open your Godot project, restart your AI assistant, and start building. If anything refuses to connect, the Troubleshooting Guide has you covered.
