## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-20.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 74/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 678 tokens (~169/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (4)

### `get_value` (~182 tokens)

Look up an item value

What one item is worth in a Roblox trading game — Flee the Facility (FTF), Murder Mystery 2 (MM2) or Adopt Me. Returns the community trade value, how wanted the item is, where it stands in its own catalogue, how often it turned up in the newest marketplace listings, and the date the numbers were collected. Use it for questions like "how much is a Chroma Luger worth in MM2". Values are community estimates, not official Roblox prices.

Input parameters:

- `game` (string): Which game. Leave it out and the item name decides.
- `item` (string, required): Item name as a player would write it, e.g. "chroma luger", "party balloons", "shadow dragon". Russian names work too and are answered with the Russian page: "теневой дракон", "ледокол 2020".

### `check_trade` (~174 tokens)

Check whether a trade is fair

Adds up both sides of a proposed trade in one game and answers win, fair or lose, with the gap in per cent. Both sides are written as the player would say them: "2 party balloons, sakura" or "neon shadow dragon". A trade that mixes two games is refused rather than calculated: the three games use different scales that cannot be added together.

Input parameters:

- `game` (string): Which game. Leave it out and the item names decide.
- `get` (string, required): What the player receives, comma separated. Russian works here too: "ледяной дракон".
- `give` (string, required): What the player gives away, comma separated. Russian works, including quantities and pet variants: "неон теневой дракон", "2 ледокол 2020 и хрома люгер".

### `list_values` (~139 tokens)

List the most valuable items

The most valuable items in one game, most valuable first, with their community values and page links. Optionally narrowed to one section of the catalogue (for MM2: godly, ancient, sets, pets, chroma, knife, gun…). Use it for "what are the most expensive knives in MM2" or to see what a game's scale looks like.

Input parameters:

- `game` (string, required): Which game to list.
- `limit` (integer): How many items to return. Default 20.
- `section` (string): MM2 only: section slug such as godly, ancient, sets, pets, chroma, knife, gun.

### `search_items` (~115 tokens)

Find items by name

Finds items across all three games by a partial name and returns the candidates with their game, value and page link. Use it when the name a player wrote is ambiguous, misspelled or could belong to more than one game, before asking get_value for the exact one.

Input parameters:

- `limit` (integer): How many candidates. Default 10.
- `query` (string, required): Part of an item name, e.g. "chroma", "dragon", "hammer" — or in Russian: "дракон", "нож".
