Available components
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 Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- 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 Usability74
- AI-judged instruction clarity (excellent).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management23
- Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 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
How do I install the FairStash — Roblox trade values MCP server?
FairStash — Roblox trade values is a hosted endpoint at https://fairstash.app/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

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 →
check_trade Check whether a trade is fair ~174
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.
| Name | Type | Req | Description |
|---|---|---|---|
| game | string | – | Which game. Leave it out and the item names decide. |
| get | string | yes | What the player receives, comma separated. Russian works here too: "ледяной дракон". |
| give | string | yes | What the player gives away, comma separated. Russian works, including quantities and pet variants: "неон теневой дракон", "2 ледокол 2020 и хрома люгер". |
No output schema declared.
No examples provided.
get_value Look up an item value ~182
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.
| Name | Type | Req | Description |
|---|---|---|---|
| game | string | – | Which game. Leave it out and the item name decides. |
| item | string | yes | 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". |
No output schema declared.
No examples provided.
list_values List the most valuable items ~139
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.
| Name | Type | Req | Description |
|---|---|---|---|
| game | string | yes | 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. |
No output schema declared.
No examples provided.
search_items Find items by name ~115
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.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | How many candidates. Default 10. |
| query | string | yes | Part of an item name, e.g. "chroma", "dragon", "hammer" — or in Russian: "дракон", "нож". |
No output schema declared.
