Category Design and Media
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security83
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation is enforced on tool calls, but the challenge carries no valid RFC 9728 metadata, so a client cannot discover where to get a token. See how to fix → View diagnostics → Fail
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability60
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1774 tokens (~136/item across 13 items; 13 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management37
- Stability observed for 11 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage76
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 29% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 13 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 14 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
approve Approve drafts ~49
No charge. Marks one draft per item copy as the reference its final is made from. Use the outputId shown by get_status.
| Name | Type | Req | Description |
|---|---|---|---|
| approvals | array | yes | – |
| projectId | string | yes | – |
No output schema declared.
No examples provided.
asset_kit Quote the matching asset kit ~105
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 after plan_kit (generate takes confirmCredits). The kit zip includes the spec files. Calling it again returns the same project.
| Name | Type | Req | Description |
|---|---|---|---|
| specId | string | yes | – |
No output schema declared.
No examples provided.
draft Draft items cheaply ~90
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.
| Name | Type | Req | Description |
|---|---|---|---|
| confirmCredits | integer | yes | – |
| itemIds | array | yes | – |
| projectId | string | yes | – |
| requestId | string | yes | – |
| variants | – | – | – |
No output schema declared.
No examples provided.
game_concept Write a game spec from an idea ~226
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.json plus GAME_SPEC.md, AGENTS.md and PROMPT.md to save in the project. Names of existing games, characters and brands are removed: specs are original games only. With an API key the spec is saved (specId) for get_spec, update_state and asset_kit.
| Name | Type | Req | Description |
|---|---|---|---|
| artStyle | string | yes | – |
| genre | string | yes | obby | simulator (also tycoon) | survivors (horde) | cozy (one-verb 3D toy) | rpg | voxel (city builder) | coop (two players) |
| idea | string | yes | One sentence in your own words. No "like <existing game>". |
| target | string | – | roblox, or web (a single-page three.js game) |
No output schema declared.
No examples provided.
generate Generate final assets ~142
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 and only the lower remaining price is charged. The same requestId returns the same jobs and charges nothing. itemIds may be "approved".
| Name | Type | Req | Description |
|---|---|---|---|
| confirmCredits | integer | yes | – |
| itemIds | – | yes | – |
| options | object | – | iconStyle: the game icon look when plan_kit listed styles.gameIcon. |
| projectId | string | yes | – |
| requestId | string | yes | – |
No output schema declared.
No examples provided.
generate_sprite_sheet Generate a game sprite sheet ~212
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 requestId returns the same order and charges nothing. Only one paid sprite order is open per account at a time. Without an API key nothing is spent: you get the price and links for the user.
| Name | Type | Req | Description |
|---|---|---|---|
| confirmCredits | integer | – | The exact price you showed the user. Required with an API key. |
| description | string | yes | – |
| extras | array | – | – |
| fromRunId | string | – | A finished web preview of the same character: keeps its character and idle sheet, so only the rest is drawn. |
| requestId | string | – | Required with an API key. A new one for each new purchase, the same one to retry. |
| style | string | yes | – |
No output schema declared.
No examples provided.
get_files Finished files ~50
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.
| Name | Type | Req | Description |
|---|---|---|---|
| projectId | string | yes | – |
No output schema declared.
No examples provided.
get_spec Read a saved game spec ~42
No charge. The saved spec (all three layers) and its handoff files. Without specId, lists your recent specs.
| Name | Type | Req | Description |
|---|---|---|---|
| specId | string | – | – |
No output schema declared.
No examples provided.
get_sprite_status Sprite sheet status ~91
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 than that.
| Name | Type | Req | Description |
|---|---|---|---|
| runId | string | yes | – |
| waitSeconds | integer | – | – |
No output schema declared.
No examples provided.
get_status Project status ~86
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.
| Name | Type | Req | Description |
|---|---|---|---|
| projectId | string | yes | – |
| waitSeconds | integer | – | – |
No output schema declared.

No output schema declared.
No examples provided.
plan_kit Plan a Roblox asset kit ~105
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.
| Name | Type | Req | Description |
|---|---|---|---|
| description | string | yes | The game idea in plain words. |
| genre | string | – | – |
| style | string | – | Art direction, e.g. "chunky pastel cartoon". |

| Name | Type | Req | Description |
|---|---|---|---|
| patch | – | yes | { milestone_status?, built?, notes? } |
| specId | string | yes | – |
No output schema declared.
