## 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 2026-09-22.

- **Endpoint Security**: 74/100
  - 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.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 75/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 795 tokens (~132/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 95/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 82% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (6)

### `list_categories` (~73 tokens)

List product categories

List the product categories that have a published tier list, newest research first. Call this first when you do not already know the exact category slug: slugs cannot be guessed reliably and every other tool takes one.

Input parameters:

- `limit` (integer)
- `query` (string): Optional filter matched against the category name and description.

Output parameters:

- `attribution` (string)
- `categories` (array)
- `count` (integer)
- `license` (object)
- `monetization` (object)
- `source_url` (string)

### `search_products` (~72 tokens)

Search ranked products

Find ranked products by name or brand across every board. Returns the slug, category and tier for each match, which is what get_product and get_tier_list need next.

Input parameters:

- `limit` (integer)
- `query` (string, required): Product or brand name, e.g. "Bambu Lab X2D".

Output parameters:

- `attribution` (string)
- `license` (object)
- `matches` (integer)
- `monetization` (object)
- `products` (array)
- `query` (string)
- `source_url` (string)

### `get_tier_list` (~119 tokens)

Get a category tier list

The full S-to-F tier list for one category: every ranked product with its tier, rank, LP, verdict, pros, cons, citation counts, GTIN barcodes and, where the maker published one, the announcement date. This is the primary tool and one call answers a "what is the best X" question completely. Call get_product for the quotes behind a placement.

Input parameters:

- `category` (string, required): Category slug, e.g. "3d-printers".
- `tier` (string): Optional. Return only this tier.

Output parameters:

- `attribution` (string)
- `category` (object)
- `license` (object)
- `method` (string)
- `monetization` (object)
- `products` (array)
- `products_ranked` (integer)
- `source_url` (string)
- `summary` (string)
- `tier_meanings` (object)

### `get_product` (~179 tokens)

Get one product

Everything held on one product: its placement, verdict, pros and cons, GTIN barcodes, the announcement date where the maker published one, and a breakdown of how the cited sources read (how many were glowing, positive, neutral or negative, and whether they were outlets, named authors, video channels or forum owners). Then every citation in full, with a verbatim quote, who said it, and whether the link was fetched and confirmed. Use this when a claim needs backing up.

Input parameters:

- `citation_limit` (integer): How many citations to return, most notable first. The sentiment and speaker breakdowns always count every source regardless of this.
- `citation_offset` (integer): Skip this many citations. Use it to page through the rest.
- `slug` (string, required): Product slug, e.g. "bambu-lab-x2d".

Output parameters:

- `attribution` (string)
- `category` (object)
- `citations` (array)
- `citations_confirmed_live` (integer)
- `citations_offset` (integer)
- `citations_remaining` (integer)
- `citations_shown` (integer)
- `citations_total` (integer)
- `license` (object)
- `monetization` (object)
- `product` (object)
- `sentiment` (object)
- `source_url` (string)
- `speaker_mix` (object)

### `compare_products` (~62 tokens)

Compare products

Compare two to five products side by side. They must share a category: LP is points on one category ladder and comparing across boards is meaningless, so a mixed request is refused rather than answered misleadingly.

Input parameters:

- `slugs` (array, required): Product slugs to compare.

Output parameters:

- `attribution` (string)
- `category` (object)
- `license` (object)
- `monetization` (object)
- `note` (string)
- `products` (array)
- `source_url` (string)

### `what_to_avoid` (~79 tokens)

What to avoid in a category

The products the research placed in the bottom tiers, and the ones it deliberately entered as traps buyers cross-shop but should not buy. Use it to answer "what should I not buy" and to check whether a product a user is considering was flagged.

Input parameters:

- `category` (string, required): Category slug, e.g. "3d-printers".

Output parameters:

- `attribution` (string)
- `bottom_tier_count` (integer)
- `category` (object)
- `flagged_count` (integer)
- `license` (object)
- `monetization` (object)
- `products` (array)
- `source_url` (string)
