Authorization (optional)

Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

draft

Costs 10 credits per draft image. Makes low-cost previews with an AI fit check so finals are only bought for what works. confirmCredits must equal the price (items x copies x variants); requestId makes a retry free.

generate

Spends credits. confirmCredits must equal the price of the items; if the price changed nothing is charged and price_changed comes back. The same requestId returns the same jobs and charges nothing. itemIds may be "approved".

Argument	Type	Description
itemIds*	any
options	object	iconStyle: the game icon look when plan_kit listed styles.gameIcon. includePreview: add the optional preview sheet to "approved".

get_files

No charge. Finished files with one-hour signed download URLs, sizes, triangle counts and stud sizes, plus a ready next-step block for Roblox Studio MCP and Open Cloud.

read-only

Argument	Type	Description
projectId*	string

      "type": "string",
      "maxLength": 64,
      "minLength": 1
    }
  }
}

get_status

No charge. One row per plan item, drafts with the AI fit verdict (fit, misfit, unjudged or pending; unjudged never blocks approve), approvals and balance. waitSeconds (0-25) returns as soon as something changes, so a call can come back earlier than that.

    }
  }
}

plan_kit

No charge. Turns a one-sentence game idea into a priced kit (GUI, icons, thumbnail, 3D props, music). With an API key the plan is saved as a project; without one you get the same plan and price plus a link for the user to connect.

Argument	Type	Description
genre	string
style	string	Art direction, e.g. "chunky pastel cartoon".
description*	string	The game idea in plain words.
