Godot — LM Studio Plugin

An LM Studio plugin (TypeScript) that lets the model drive the Godot game engine and look up the official Godot documentation while it works.

This is a native LM Studio Plugin, not a standalone MCP server. Tools are exposed directly to the model through @lmstudio/sdk, and per-chat settings are rendered automatically by LM Studio from a config schema.

Features

Godot engine tools

Tool	Description
`launch_editor`	Launch the Godot editor for a project directory.
`run_project`	Run a project in debug (headless) mode and capture output.
`get_debug_output`	Return captured stdout/stderr of the running project.
`stop_project`	Stop the running project and return its final output.
`get_godot_version`	Return the resolved Godot executable version.
`list_projects`	Find Godot projects inside a directory.
`get_project_info`	Project metadata: name, path, version, file-type breakdown.
`create_scene`	Create a new scene with a root node type.
`add_node`	Add a node to an existing scene.
`load_sprite`	Load a texture into a Sprite2D / Sprite3D / TextureRect.
`export_mesh_library`	Export a 3D scene as a MeshLibrary `.res`.
`save_scene`	Save a scene, optionally writing a variant.
`get_uid`	Get the UID for a file (Godot 4.4+).
`update_project_uids`	Refresh UID references across a project (Godot 4.4+).

Error handling: The engine tools validate paths, class names and scene existence before calling Godot. When the Godot executable cannot be launched (for example it is not installed, or the path is wrong), they return a clear Error: Failed to spawn Godot executable "<path>": <ENOENT|EACCES|EPERM> message instead of silently reporting success. Set the godotPath setting or the GODOT_PATH environment variable, or install Godot Engine.

Documentation tools (new)

Tool	Description
`search_godot_docs`	Search the official Godot docs and return matching pages (title, URL).
`fetch_godot_docs`	Fetch and return the readable text of a single docs page.

The docs search page renders results with client-side JavaScript only, so this plugin queries the underlying Sphinx search index (searchindex.js) directly on the server side — no browser required. Results are cached per-doc-version.

Per-chat settings

Rendered automatically by LM Studio. All are optional and have sane defaults.

Key	Type	Default	Description
`docsMaxResults`	numeric	`5`	Max results from the docs search tool.
`docsMaxChars`	numeric	`20000`	Max characters returned by the docs fetch tool.
`docsVersion`	select	`stable`	Docs version to query (stable/beta/4.3/4.4/5.0).
`godotPath`	string	(empty)	Explicit Godot executable path (overrides `GODOT_PATH`).
`toolsEnabled`	boolean	`true`	Toggle the engine-control tools. Docs tools are always available.

Requirements

LM Studio with the Plugin runtime (Node.js).
Godot Engine installed, or set the GODOT_PATH environment variable / godotPath setting. If the executable is missing or cannot be launched, the engine tools report a clear Failed to spawn Godot executable ... <ENOENT|EACCES|EPERM> error instead of silently succeeding.

Development

Then in LM Studio: open the plugin list → enable godot-mcp → open a model that supports tool calling → confirm the tools are listed and callable.

lms (the LM Studio CLI) is required for lms dev / lms push. Build, typecheck and lint run locally without it.
