AI Skills, MCP Tools, and CLI for Unity Engine. Full AI develop and test loop. Use cli for quick setup. Efficient token usage, advanced tools. Any C# method may be turned into a tool by a single line. Works with Claude Code, Gemini, Copilot, Cursor and any other absolutely for free.
Unity-MCP connects AI coding agents to the Unity game engine through MCP, letting them work with the Unity Editor and running games. It is used by game developers to generate code, automate development and testing, debug projects, and add AI-driven behavior to games. The catalogue entries provide skills, instructions, an MCP integration, and settings for operating this workflow.
This repository also configures its own agents. See what Unity-MCP tells them →
Skill Claude Code
Destroy one or more Components from a target GameObject. Missing (null) components are skipped — they cannot be destroyed. Use 'gameobject-find' and 'gameobject-component-get' to identify the components first.
Skill Claude Code
Get detailed information about a specific Component on a GameObject — type, enabled state, and (optionally) serialized fields and properties. Supports token-saving path-scoped reads via paths or viewQuery. Use 'gameobject-find' to list components first.
Skill Claude Code
List the fully-qualified C# type names of every concrete UnityEngine.Component subclass available in the project. Paginated (default 5/page, max 500). Use this to find a valid componentName for 'gameobject-component-add'.
Skill Claude Code
Modify a specific Component on a GameObject in opened Prefab or in a Scene. Allows direct modification of component fields and properties without wrapping in GameObject structure. Use 'gameobject-component-get' first to inspect the component structure before modifying. Three modification surfaces are available…
Skill Claude Code
Create a new GameObject in the currently opened Prefab or active Scene, optionally parented under another GameObject and pre-positioned. Pass primitiveType to spawn a Unity primitive (Cube, Sphere, etc.) instead of an empty GameObject.
Skill Claude Code
Destroy a GameObject (and all nested children) in the currently opened Prefab or active Scene. Returns the destroyed GameObject's name, path, and instance ID for confirmation. Use 'gameobject-find' to locate the target first.
Skill Claude Code
Duplicate a batch of GameObjects in the currently opened Prefab or active Scene. Marks each affected scene as dirty after duplication. Use 'gameobject-find' to locate the source GameObjects first.
Skill Claude Code
Find a specific GameObject in the opened Prefab (preferred when present) or the active Scene. Optionally include editable data, components preview, bounds, and limited hierarchy. Supports token-saving path-scoped reads via paths or viewQuery.
Skill Claude Code
Modify GameObject fields and properties in opened Prefab or in a Scene. You can modify multiple GameObjects at once. Just provide the same number of GameObject references and SerializedMember objects. Three modification surfaces are available per GameObject (gameObjectDiffs, pathPatchesPerGameObject…
Skill Claude Code
Reparent a batch of GameObjects under a new parent in the currently opened Prefab or active Scene. Per-item failures are reported in the returned status string instead of aborting the batch. Use 'gameobject-find' to locate the GameObjects first.
Skill Claude Code
Get serialized data for a Unity UnityEngine.Object — all serializable fields and properties. Supports token-saving path-scoped reads via paths or viewQuery. Pair with 'object-modify' when you need to write back.
Skill Claude Code
Modify a Unity UnityEngine.Object's serializable fields/properties. Three modification surfaces are available (objectDiff, pathPatches, jsonPatch) — see the skill body. Use 'object-get-data' first to inspect the object structure.
Skill Claude Code
Install a Unity package from the registry, a Git URL, or a local path. Modifies manifest.json and triggers package resolution; may also trigger a domain reload — the final result is delivered after the reload via the request's requestId. Use 'package-search' / 'package-list' for discovery first.
Skill Claude Code
List all UPM packages installed in the Unity project — name, version, source, description. Optionally filter by source (registry, embedded, local, git, built-in, local tarball), by name/display/description substring, and by direct-dependency-only.
Skill Claude Code
Uninstall a UPM package from the Unity project. Modifies manifest.json and may trigger a domain reload — the final result is delivered after the reload via the request's requestId. Built-in packages and packages that are dependencies of others cannot be removed. Use 'package-list' to list installed packages first.
Skill Claude Code
Search Unity's package registry plus locally installed packages (Git, local, embedded sources) by query string. Returns available versions and installation status. Online mode fetches exact matches from the live registry then supplements with cached substring matches.
Skill Claude Code
Lightweight readiness probe. Returns the input message echoed back, or 'pong' when omitted. Useful for CLI health checks and SignalR connectivity smoke tests.
Skill Claude Code
Capture the current frame's timing info (delta time, FPS, frame counts, runtime). Snapshot only — historical frames live in Unity's Profiler window.
Skill Claude Code
Discard all frames currently held by the Editor Profiler (UnityEditorInternal.ProfilerDriver.ClearAllFrames). Cannot be undone.
Skill Claude Code
Toggle the wrapper's local 'enabled' flag for a named profiler module. Bookkeeping only — Unity's runtime API does not expose direct module control; for real module visibility use the Profiler window.
Skill Claude Code
Return memory statistics snapshot from UnityEngine.Profiling.Profiler — reserved, allocated, mono heap, graphics, etc. (in MB).
Skill Claude Code
Return current frame timing, FPS, vsync, target frame rate, threading mode, and graphics device type from Unity Time / QualitySettings / SystemInfo.
Skill Claude Code
Return script execution timing (frame time, fixed dt, time scale, frame count, runtime) plus Mono / GC memory usage in MB.
Skill Claude Code
Return the Unity profiler's current enabled state, active modules, max-used memory, and platform support flag. Read-only.
