Tools 13 found in our last check

  • 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.

  • draft

    Costs 13 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.

  • approve

    No charge. Marks one draft per item copy as the reference its final is made from. Use the outputId shown by get_status.

  • generate

    Spends credits. confirmCredits must equal the price of the items; if the price changed nothing is charged and price_changed comes back. Credits paid for an item's draft count toward that item's final (draft + final = the quoted price): confirming the plan_kit price is accepted a…

  • 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.

  • 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.

  • list_projects

    No charge. Your recent projects, newest first.

  • generate_sprite_sheet

    Spends credits (180, plus 50 for each extra animation, at most 2). Draws one character from a description in a chosen style with idle, run and attack animations and delivers the sheet, GIFs, frames and JSON via get_sprite_status. confirmCredits must equal the price; the same req…

  • get_sprite_status

    No charge. Progress of a sprite sheet order. When it is done: signed one-hour download links for the sprite sheet PNG, one GIF per animation, a frames zip, the sheet JSON and the character. waitSeconds (0-25) returns as soon as something changes, so a call can come back earlier…

  • game_concept

    No charge. Turns a genre preset, an art-style preset and a one-line idea into a short game spec your coding agent can build from: intent (frozen), plan (milestones with testable done_when, playtest, asset manifest) and state (you update it with update_state). Returns game_spec.j…

  • get_spec

    No charge. The saved spec (all three layers) and its handoff files. Without specId, lists your recent specs.

  • update_state

    No charge. Updates ONLY the STATE layer of a saved spec: milestone_status ({milestoneId: todo|doing|done|blocked}), built (lines appended) and notes (appended). The intent and the plan cannot be changed here; if the intent looks wrong, ask the human.

  • asset_kit

    No charge here. Plans the assets a saved spec needs (GUI set with its finished screen, icons, thumbnail, props, music) in the spec's style and returns one total in credits plus a kit projectId. Show the user the total; then draft/approve/generate on that projectId exactly as aft…
