Quartermaster MCP server

Quartermaster is a helper that keeps an index of all the game assets you own, gathered from stores like the Unity Asset Store, Fab, Quixel Megascans, Gumroad and Leartes Cosmos. It runs on your own computer and lets your AI assistant search that library for you. It is handy if you build games or 3D scenes and have a pile of bought or free assets you never remember.

What this MCP server does

You ask your AI a question about your game assets, in plain words. The AI passes that question to Quartermaster. Quartermaster searches its local index of everything you own, using keywords, meaning-based search and even the pictures in the listings. It hands back a list of matching assets, with details like where they come from and whether they are already downloaded. Your AI then explains the results to you in the chat.

What you can do with it

• Find assets you own that match a description, even if the listing never uses your words
• Search by look and feel, using the screenshots and promo images of your assets
• Check whether two assets will work together or clash in your project
• See whether an asset is already downloaded on your disk or still in the cloud
• Unpack a downloaded package straight into your project's Assets folder
• Get full details on a single asset, including its store page and gallery
• Audit a project to see its engine, version and render pipeline

What it gives back to you

You get a list of matching assets, each with its name, source store, and a short note on why it matched. Some results include physical details like scan size or texture maps. You also get answers to questions like whether two assets conflict, or whether something is already on your disk. If you ask it to unpack a package, it tells you what it placed into your project folder.

Before you start

Who it's for

Game developers, 3D artists and hobbyist builders who own a lot of assets from Unity, Fab, Megascans, Gumroad or Cosmos and want their AI to help them use what they already have.
