Lists scenes (.tscn), scripts (.gd), and resources (.tres/.res) in a Godot project folder, relative to project_path.

Parses a .tscn file and returns its node tree as JSON (name, type, parent path, properties).

Creates a new .tscn file with a single root node. Use add_node afterward to build out the tree.

Adds a child node to an existing scene at the given parent path (use "." for the scene root).

Removes a node (and its descendants) from a scene.

Sets or overwrites one or more properties on an existing node in a scene.

Creates or fully overwrites a GDScript (.gd) file.

Reads a GDScript (.gd) file's contents.

Replaces one exact occurrence of old_text with new_text in a GDScript file (like a find-and-replace patch).

Runs the Godot project headlessly (no window) for a fixed duration to catch parse/runtime errors, or runs a specific scene headlessly. Requires the godot4 binary (or GODOT_BIN env var) to be installed.

Checks whether the Godot editor is running with the godot_mcp_bridge plugin enabled.

Tells the running Godot editor to play a specific scene (like pressing the Play Scene button).

Tells the running Godot editor to stop the currently playing scene.

Returns the currently selected node(s) in the Godot editor.

Returns the scene currently open in the Godot editor as a node tree, plus the list of open scenes.

Opens a scene in the Godot editor (switching to its tab) so it can be edited live with editor_add_node, editor_set_properties and editor_remove_node.

Adds a node to the scene open in the Godot editor. It appears live and is selected; undo with Ctrl+Z. The scene is not saved until editor_save_scene (or the user saves). Prefer this over add_node while the editor is open.

Sets properties on a node in the scene open in the Godot editor (live, undoable with Ctrl+Z, not saved until editor_save_scene).

Removes a node (and its descendants) from the scene open in the Godot editor (live, undoable with Ctrl+Z).

Saves the scene currently open in the Godot editor to disk (like Ctrl+S).
