What this server can do
8 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
compare_gear(product_ids)- 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). Required: product_ids.
find_lighter_alternative(limit, product_id)- 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). Required: product_id.
get_field_consensus(slug, product_id)- 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. Pass either the product UUID or the slug.
get_gear_reviews(product_id)- Fetch creator video reviews for a product. Returns up to 10 verified mentions with creator name, YouTube ID, timestamp, and quoted snippet. Required: product_id.
get_pack_template(slug, template_id)- Return one of the 21 in-house TrailWeights pack templates by ID or slug, including the full item list and total weight.
get_product_specs(slug, product_id)- 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.
recommend_gear(limit, query, category, weight_cap_oz)- Deterministic, fast (<500ms) structured gear lookup from a freeform query (e.g. 'best quilt for a PCT thru hike'). Runs the TrailWeights deterministic query planner — rule-based category/intent detection, brand-alias expansion, and compiled weight/price/category constraints; no server-side LLM is invoked. Returns the top catalog products ranked by the compiled plan (verified weight, relevance, price) with verified weights (provenance and conflict flags), trust envelopes with field-consensus signal, citations, and cottage-first buy URLs, plus the applied filters. The calling agent supplies the reasoning; this tool supplies verified data. Optional weight cap (oz) and category filter. Required: query.
search_corpus(query, category, match_count, max_weight_g, max_price_usd, source_filter, min_creator_count)- 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. Required: query.

Signals
These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
