Godot MCP - Full Control

A comprehensive Model Context Protocol (MCP) server that gives AI assistants full control over the Godot game engine. 157 tools spanning networking, 3D/2D rendering, UI controls, audio effects, animation trees, file I/O, runtime code execution, property inspection, scene manipulation, signal management, physics, project creation, and more.

Acknowledgments

This project is built upon and extends godot-mcp by Solomon Elias (Coding-Solo). The original project provided the foundational architecture including the TypeScript MCP server, headless GDScript operations system, and TCP-based runtime interaction server. Thank you for making this possible with your excellent open-source work!

What's New (Improvements Over Original)

The original godot-mcp provided 20 tools for basic project management and scene creation. This fork extends it to 157 tools with the following major additions:

New in 3.1

• validate_script autoload resolution - Script validation now compiles the target through a SceneTree at _initialize() (after project autoloads are registered) instead of --check-only at _init(). References to autoload singletons no longer produce false Identifier not found errors, while real syntax/type errors are still caught. Verified building a full game whose scripts reference several autoloads.
• manage_input_map event merging - Adding a second key to an existing input action now merges it into that action's events array (with physical_keycode de-duplication) instead of writing a duplicate actionname= line, which previously left project.godot malformed and silently dropped earlier bindings.

New in 3.0

• .NET / C# support - Scaffold C# projects and generate C# scripts (create_project with dotnet: true, create_csharp_script); the .csproj SDK version is matched to your installed Godot.
• GDScript diagnostics - Validate scripts for syntax and type errors without running the game (validate_script, and validate_scripts for all git-changed or project-wide files).
• Correctness and robustness fixes across the headless scene operations and the runtime interaction server (resource-typed properties now persist, reparenting works, runtime commands are correlated by request id, and the tools survive projects with warnings-as-errors). Requires Godot 4.4 or later; tested and working with the latest Godot 4.7.

Runtime Code Execution

• game_eval - Execute arbitrary GDScript code in the running game with return values
• Full await support for async GDScript code
• Works even when the game is paused (PROCESS_MODE_ALWAYS)

Runtime Node Inspection & Manipulation

• game_get_property / game_set_property - Read/write any property on any node by path
• game_call_method - Call any method on any node with arguments
• game_get_node_info - Full node introspection: properties, signals, methods, children
• game_instantiate_scene - Dynamically add scenes to the running game
• game_remove_node - Remove nodes at runtime
• game_change_scene - Switch scenes at runtime
• game_reparent_node - Move nodes between parents

Signal System

• game_connect_signal - Wire up signal connections at runtime
• game_disconnect_signal - Remove signal connections
• game_emit_signal - Emit signals with arguments

Animation & Tweening

• game_play_animation - Control AnimationPlayer (play, stop, pause, list)
• game_tween_property - Smooth property animation with configurable easing

Game Control & Debugging

• game_pause - Pause/unpause the game
• game_performance - FPS, frame time, memory, object counts, draw calls
• game_wait - Wait N frames (timing-sensitive operations)
• game_get_nodes_in_group - Query nodes by group
• game_find_nodes_by_class - Find all nodes of a specific class

Headless Scene Operations (No Running Game Needed)

• read_scene - Parse any .tscn file and get full node tree with properties as JSON
• modify_scene_node - Change node properties in scene files
• remove_scene_node - Remove nodes from scene files
• attach_script - Attach GDScript files to nodes in scenes
• create_resource - Create .tres resource files (materials, themes, etc.)

Project Management

• read_project_settings - Parse project.godot as structured JSON
• modify_project_settings - Change project settings programmatically
• list_project_files - List and filter project files by extension

File I/O

• read_file / write_file / delete_file - Full file system access within Godot projects
• create_directory - Create directory structures for scripts, scenes, assets

Error & Log Capture

• game_get_errors - Get new push_error/push_warning messages since last call
• game_get_logs - Get new print output from the running game since last call

Enhanced Input

• game_key_hold / game_key_release - Hold keys down for movement testing (WASD etc.)
• game_scroll - Mouse scroll wheel events
• game_mouse_drag - Drag between two points over multiple frames
• game_gamepad - Gamepad button and axis input events

Project Creation & Configuration

• create_project - Create a new Godot project from scratch (pass dotnet: true to scaffold a .NET/C# project)
• create_csharp_script - Create a C# script in a Godot .NET project
• manage_autoloads - Add, remove, or list autoloads
• manage_input_map - Add, remove, or list input actions and key bindings
• manage_export_presets - Create or modify export preset configuration

.NET / C# Support

• create_project with dotnet: true - Scaffold a Godot .NET project (.csproj with Godot.NET.Sdk matched to your Godot version, plus the "C#" feature flag)
• create_csharp_script - Generate an idiomatic C# script (partial class, correct _Ready/_Process override signatures); the class name is kept in sync with the file name so Godot can attach it
• get_project_info reports an isDotnet field

GDScript Diagnostics

• validate_script - Check a single GDScript file for syntax and type errors headlessly, returning { valid, errors: [{ message, file, line }] }
• validate_scripts - Batch-validate all git-changed .gd files (or the whole project), so an agent can verify its edits before running the game
