glade-mcp — Unity and Godot MCP server: what it does, how to install
An MCP server that wires AI clients into the Unity and Godot editors: scenes, scripts, physics, materials.
claude mcp add glade-mcp -- uvx gladekit-mcpWhat glade-mcp does
The server probes both ports at startup and exposes the tool set that matches the running editor — Unity on :8765, Godot on :8766. Unity gets 275 tools across 20 categories, Godot 115 across 17: scenes and nodes, scripts, resources, signals, physics, 2D, audio, particles, animation, UI, lighting, export. Shared between them are one-call gameplay scaffolders (controllers, enemies, combat, menus, save system), a verification loop with screenshots and runtime-event observation, and surgical script editing with find_references and rename_symbol.
Each engine needs its bridge. Unity installs as a UPM package from a git URL in Package Manager and starts on its own. For Godot you drop the com.gladekit.mcp-bridge/ folder into the project's addons/ directory and enable the plugin in project settings. The bridge is editor-only and never runs in an exported game. Godot Mono and C# projects are not supported yet, so plan around GDScript.
Your AI client launches the server for you. You need uv installed, since the server runs as uvx gladekit-mcp. With both editors open at once, auto-detection can't decide — pin one with GLADEKIT_MCP_FORCE_ENGINE=unity or =godot.
What it helps with
- build a scene and place nodes without leaving the editor
- find every reference to a symbol and rename it across the project
- check how the game looks at runtime from screenshots
- scaffold a controller, enemies and menus in one call
- export the project for a target platform
Example prompts for the agent
- Build a level scene with a player, a camera and a couple of enemies
- Find all references to
PlayerControllerand rename it toHeroController - Take a screenshot of the game view and tell me what's happening on screen

Questions about glade-mcp
How do I install glade-mcp in Claude Code?
Install uv first, then run claude mcp add glade-mcp -- uvx gladekit-mcp. You also need the bridge for your engine: the UPM package for Unity, or the com.gladekit.mcp-bridge/ folder in addons/ for Godot.
What does glade-mcp do?
It connects an AI client to the Unity or Godot editor and gives the agent tools for scenes, scripts, physics, materials, animation and export.
Which Unity and Godot versions are supported?
Unity 2021.3 and newer, Godot 4.3 and newer with GDScript. Godot Mono and C# projects are not supported.
