Tools (8)

`compare_gear`	Compare two to six products using bounded spec rows, selected options, weight provenance and source links. Missing products are identified explicitly.
`find_lighter_alternative`	Up to six lighter alternatives preserving the source product function, with verified weights, savings, selected options and source links.
`get_field_consensus`	Bounded field-consensus label, confidence, evidence count and source links for one product. Internal scores, evidence claims and source quotations are not returned. Pass the product UUID or slug.
`get_gear_reviews`	Creator review provenance for one product: at most three mentions with creator name, source URL, timestamp and sentiment. Transcript text is not returned.
`get_product_specs`	Bounded canonical facts for one product: weight, price, selected option, up to six specs, provenance and source links. Includes weight confidence and conflict flags. Source quotations are not returned. Pass the product UUID or slug.
`recommend_gear`	Up to six catalog recommendations from the deterministic TrailWeights query planner. Returns verified weight and price on the same selected option, provenance and source links. Optional weight cap in ounces and category filter. No server-side LLM.
`report_outcome`	Optionally report whether a prior TrailWeights MCP result was used, cited, or helpful. The request_id must come from that result and the reporting caller must match the original caller. This writes telemetry only; it never changes catalog or account data.
`search_corpus`	Bounded decision evidence from the public catalog using the TrailWeights deterministic planner. Returns at most three product facts with source URLs. No raw corpus text, source slicing, or similarity scores.
