## 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 2026-08-03.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 8 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - 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**: 71/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 869 tokens (~108/item across 8 items; 8 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 90/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 70% of tool parameters carry a description.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

## MCP tools (8)

### `search_corpus` (~208 tokens)

Semantic search over the TrailWeights knowledge corpus (transcripts, product descriptions, in-house pack templates, surveys, ultralight Bible). Returns the top matching chunks with source attribution. Supports hard predicates — filter by verified max weight (grams), max price (USD), minimum independent creator count (trust floor), and gear category — so hybrid semantic+spec queries resolve in one call.

Input parameters:

- `category` (string): Gear category filter (e.g. shelter, pack, sleep_system).
- `match_count` (integer)
- `max_price_usd` (number): Only chunks tied to products at or under this MSRP.
- `max_weight_g` (number): Only chunks tied to products at or under this verified weight in grams.
- `min_creator_count` (integer): Trust floor: only chunks tied to products mentioned by at least this many independent creators.
- `query` (string, required): Natural-language search query.
- `source_filter` (string): Restrict results to a single corpus source type.

### `get_gear_reviews` (~51 tokens)

Fetch creator video reviews for a product. Returns up to 10 verified mentions with creator name, YouTube ID, timestamp, and quoted snippet.

Input parameters:

- `product_id` (string, required): TrailWeights product UUID.

### `get_product_specs` (~104 tokens)

Canonical product spec sheet — name, brand, category, verified weight, MSRP, image, and a cottage-first affiliate buy URL. Includes a trust envelope: verified weight with provenance (measured vs manufacturer claim), confidence, last-verified date, a manufacturer-vs-field weight conflict flag, and top creator citations with source URLs. Pass either the product UUID or the slug.

Input parameters:

- `product_id` (string): Product UUID.
- `slug` (string): Product slug.

### `recommend_gear` (~146 tokens)

Structured gear recommendations from a freeform natural-language query (e.g. 'best quilt for a PCT thru hike'). Runs the TrailWeights query planner: intent classification, brand-alias expansion, and compiled weight/price/category constraints. Returns the top catalog products with verified weights (with provenance and conflict flags), citations, and cottage-first buy URLs, plus the interpreted intent and applied filters. Optional weight cap (oz) and category filter.

Input parameters:

- `category` (string): Optional category filter (e.g. backpack, sleeping_bag, shelter).
- `limit` (integer)
- `query` (string, required)
- `weight_cap_oz` (number): Maximum weight in ounces.

### `compare_gear` (~65 tokens)

Side-by-side spec comparison for 2–6 products. Returns aligned rows of name, weight, price, category, and buy URL, each with a trust envelope (verified weight provenance, manufacturer-vs-field conflict flag, top citations).

Input parameters:

- `product_ids` (array, required)

### `find_lighter_alternative` (~65 tokens)

Given a product, return up to 5 lighter alternatives in the same category, ordered by verified weight ascending. Each alternative carries a trust envelope (verified weight provenance, conflict flag, top citations).

Input parameters:

- `limit` (integer)
- `product_id` (string, required)

### `get_field_consensus` (~96 tokens)

Pre-computed field consensus for a product: what independent creators and the field say, scored on a deterministic 100-point rubric with a source-diversity gate. Returns the consensus label, score, evidence count, distinct authors, known conflicts, and a sample of the underlying evidence claims with source URLs. This is conflict-resolution an agent would otherwise have to reconstruct from raw reviews.

Input parameters:

- `product_id` (string, required): Product UUID.

### `get_pack_template` (~56 tokens)

Return one of the 21 in-house TrailWeights pack templates by ID or slug, including the full item list and total weight.

Input parameters:

- `slug` (string): Pack template slug.
- `template_id` (string): Pack template UUID.
