godot-mcp

godot-mcp is a skill for Claude Code, Codex from jxoesneon/Ciel. It costs 42 tokens per session (1,085 once invoked), scanned A, original, Apache-2.0.

A bridge between a coding agent and the Godot 4 game editor, allowing live inspection, scripting, scene changes, screenshots, and error checks. Godot is a game engine for making 2D and 3D games.

In plain words
What is it for?
It helps inspect and edit scenes, run GDScript, capture game or editor views, construct scene nodes, and monitor runtime errors.
Why use it?
It removes the need to switch constantly between code, the editor, and runtime checks when developing a game.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

godot-mcp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

CIEL ADAPTATION: Godot MCP & Visual Verification

Bridges LLM reasoning with live Godot 4 editor execution via the godot-mcp MCP server. Provides real-time introspection, visual screenshot verification, live GDScript evaluation, and runtime error telemetry. Ciel's runtime safety gates handle execution gating; this skill declares shell/network side effects from the TCP bridge (port 6505) and GDScript execution.

Tool Domains

  • Visual Verification: take_screenshot, focus_editor_viewport_3d — high-res capture of 3D/2D viewports, running scenes, editor windows with artifact auto-save.
  • Live Editor Bridge: get_editor_selection, set_editor_selection, get_active_script_editor, execute_gdscript — introspection, node selection, camera framing, live GDScript eval with UndoRedo.
  • Debugger Telemetry: get_debugger_errors, clear_debugger_errors, get_debugger_error_counts — runtime error detection, warning audits, break session tracking.
  • Scene/Node Authoring: add_node, modify_node_properties, delete_node, reparent_node, instantiate_scene — programmatic scene tree construction.
  • Shaders & Audio: create_shader_material, set_shader_parameter, configure_audio_bus, create_audio_stream_player — material overrides, uniform binding, audio bus routing.

Screenshot Target Modes

  • viewport_3d: Active 3D editor viewport (frame target via focus_editor_viewport_3d first).
  • viewport_2d: 2D scene canvas (CanvasLayer UI, Control hierarchy, HUDs).
  • main_screen / editor: Full editor interface (docks, scene tree, inspector).
  • scene + scene_path: Headless/offscreen SubViewport render of any .tscn — no editor focus required.
  • output_path: Direct disk write (e.g. <artifactDir>/screenshots/view.png); returns markdown image link ![Label](file://...).
  • Options: format (png/jpg/webp), max_width/max_height (Lanczos downscale), quality (0.0–1.0).

Live Script Execution (execute_gdscript)

  • Instantiates a clean @tool GDScript object via script.new().
  • Runs synchronously on the Godot editor thread with full access to EditorInterface, ClassDB, ProjectSettings, RenderingServer.
  • Use for: querying live node properties, inspecting singleton states, one-shot verification routines.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
