Kitpop MCP

Put the game art you made on Kitpop (icons, thumbnails, UI images, textures and 3D models) into your Roblox game from any assistant that supports MCP. Together with Roblox Studio's own MCP server you can say:

"Get my Candy Obby pack from Kitpop and set up the game icon."

These tools only read your Kitpop account and download your files. They never spend credits.

Quick start

1. Get a code: on kitpop.app open Account → Connections → Kitpop Bridge → Get a code (valid 10 minutes).

2. Link this computer (type your code instead of ABC123):

   npx -y kitpop-mcp link ABC123
   

3. Add Kitpop to your assistant, then restart the assistant:

   Assistant	How
   Claude Code	claude mcp add kitpop -- npx -y kitpop-mcp (or install the plugin below, which includes it)
   Claude Desktop	Settings → Developer → Edit Config, add the JSON below
   Cursor	~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project), add the JSON below

   {
     "mcpServers": {
       "kitpop": { "command": "npx", "args": ["-y", "kitpop-mcp"] }
     }
   }
   

   On Windows, if npx is not found, use "command": "cmd", "args": ["/c", "npx", "-y", "kitpop-mcp"].

4. Connect Roblox Studio so your assistant can put the files in your game (next section).

Requires Node.js 20.15 or newer.

Connect Roblox Studio

Roblox Studio has a built-in MCP server (Roblox docs).

1. In Studio: Assistant → … → Manage MCP Servers → turn on Enable Studio as MCP server. Supported assistants can be switched on right there under Quick connect.
2. Or add it by hand:
   • Windows: claude mcp add Roblox_Studio -- cmd.exe /c %LOCALAPPDATA%\Roblox\mcp.bat (JSON configs: "command": "cmd.exe", "args": ["/c", "%LOCALAPPDATA%\\Roblox\\mcp.bat"])
   • macOS: claude mcp add Roblox_Studio -- /Applications/RobloxStudio.app/Contents/MacOS/StudioMCP
   • WSL (assistant in Linux, Studio on Windows): claude mcp add Roblox_Studio -- cmd.exe /c '%LOCALAPPDATA%\Roblox\mcp.bat', and set KITPOP_DOWNLOAD_DIR=/mnt/c/Users/<you>/Downloads/Kitpop so Studio can see the downloaded files.
3. Restart the assistant. Studio shows a green dot under Manage MCP Servers once it is connected.

Kitpop for Roblox: Claude Code plugin with 5 skills

The plugin adds ready-made skills and starts the Kitpop MCP server for you (link your account first, step 2 above; connect Roblox Studio yourself). In Claude Code:

/plugin marketplace add diaboyy/kitpop-mcp
/plugin install kitpop-for-roblox@kitpop

Skill	What it does
game-icon-and-thumbnails	Picks the icon and 16:9 thumbnails from your pack, downloads them and tells you where they go in Game Settings
shop-ui-from-pack	Builds a mobile-friendly shop ScreenGui from your pack's own panel, button and item images
gamepass-icons	Uploads game pass / developer product icons and gives you the asset id list (optionally as a ModuleScript)
logo-sign	Puts your logo on a SurfaceGui sign standing on the ground in front of the camera
insert-3d-model	Brings a Kitpop 3D model into your place, stands it on the ground, scales and anchors it

Every skill tells you what it will change first. Studio changes can be undone with Ctrl+Z, and the skill checks the result with a screenshot. Test them in an empty place first.

Tools

Tool	What it does
kitpop_whoami	Linked account (masked email) and credit balance
kitpop_list_packs	Your packs with finished images, and your 3D models
kitpop_get_pack	Every image in a pack (group, exact category such as gamepass or badge, name, size) and the pack's 3D models
kitpop_download_asset	Saves the full-resolution original of one image (PNG) or 3D model (GLB or FBX) and returns its path

How it fits with Studio: kitpop_download_asset also returns uploadUrl for images, a one-time link on your own computer (see Privacy). Studio's upload_image only takes http(s) links, so the assistant passes that link and gets back rbxassetid://<id>. 3D models are brought in with Studio's Import 3D or with Insert in the Kitpop Bridge plugin; the assistant then places them. Roblox allows 20,000 triangles per mesh; for bigger models use Kitpop Bridge, which brings a simplified copy.

Privacy

• Your Kitpop link stays on your computer. link saves a token in ~/.config/kitpop/credentials.json (%APPDATA%\kitpop\ on Windows), readable only by you. You can use the KITPOP_TOKEN env instead. The token is never printed, logged or shown to the assistant, and it is only sent to the Kitpop server that issued it.
• Only your own files. The server talks to kitpop.app and to the short-lived download links kitpop.app gives it. It reads your packs and models and saves files to ~/Downloads/Kitpop (or KITPOP_DOWNLOAD_DIR). No analytics, no other services.
• Upload links are local and one-time. uploadUrl is served on 127.0.0.1 only (not your network), works for a single download of that one file, expires after 30 minutes, and the little file server stops when nothing is left.
• Uploads to Roblox are done by Studio, under the Roblox account signed in to Studio.
• Cut access any time: npx -y kitpop-mcp logout removes the token from this computer; Account → Connections → Manage → Disconnect on kitpop.app turns it off everywhere.

Commands and settings

npx -y kitpop-mcp link <CODE>   # link this computer
npx -y kitpop-mcp status        # show the linked account
npx -y kitpop-mcp logout        # remove the token from this computer

Env variable	Default
KITPOP_TOKEN	–	Token instead of the saved file
KITPOP_DOWNLOAD_DIR	~/Downloads/Kitpop	Where files are saved (<dir>/<pack>/…, <dir>/models/…)
KITPOP_API_URL	https://kitpop.app	For Kitpop development only

Development

npm install
npm test            # builds, then runs end-to-end tests against a local mock of the Kitpop API
npm run live-check  # against kitpop.app with your linked account (spends no credits)
claude --plugin-dir .   # try the plugin and skills from this folder
