TrailWeights MCP Server
Model Context Protocol server for the TrailWeights ultralight gear corpus: verified product weights, canonical specs, creator video reviews with timestamps, and pre-scored field consensus. Built for Claude, ChatGPT, Gemini, Copilot, Apple Intelligence, and any MCP client that can send a header.
Live status page, key request, and pricing: https://trailweights.com/mcp
Transport
Streamable HTTP — JSON-RPC 2.0 over POST https://trailweights.com/api/mcp.
Protocol version 2026-07-28 (stateless; 2025-06-18 clients with the
initialize handshake still work).
Auth
API key, required on every tool call. Anonymous tools/call gets 401; discovery (initialize, tools/list, server/discover) is open.
x-trailweights-key: <key>— or —Authorization: Bearer <key>
Get a key at https://trailweights.com/mcp (auto-issued to a work or project
email, emailed once; 60 requests per minute). Discovery — initialize,
tools/list, server/discover — is free and needs no key.
Every tool call is paid, from the first one. There is no free allowance.
- One credit from a prepaid pack: $49 for 5,000 calls, $199 for 25,000.
- Or $0.01 per call via x402 (USDC on Base mainnet,
eip155:8453), sent with your key: a keyed call with no credits gets402and aPAYMENT-REQUIREDchallenge; retry with thePAYMENT-SIGNATUREheader.
Payments never replace the key — an anonymous paid call still gets 401.
Rate-limit headers (x-ratelimit-limit, x-ratelimit-remaining,
x-ratelimit-reset) ride every response.

search_corpus | query, source_filter?, match_count? | Top semantic matches across creator transcripts, products, packs, surveys, and the curated gear knowledge base. |
get_product_specs | product_id or slug | Name, brand, category, verified weight (g & oz), price, image, buy URL. |
recommend_gear | query, weight_cap_oz?, category?, limit? | Deterministic recommendations with verified weights and buy links (no server-side LLM). |
compare_gear | product_ids[] (2–6) | Side-by-side: name, brand, category, weight, price, buy URL. |
find_lighter_alternative | product_id, limit? | Lighter same-category candidates sorted by verified weight, with weight_savings_g. |
get_gear_reviews | product_id | Up to 10 verified creator mentions with youtube_url, timestamp_seconds, and snippet. |
get_field_consensus | product_id or slug | What independent creators and the field agree on, scored on a deterministic 100-point rubric with a source-diversity gate. |
report_outcome | request_id, answer_used?, citation_included?, helpfulness? | Tell TrailWeights whether a prior result was used or cited. Telemetry only. |
Every tool result carries a TrailWeights request_id
(_trailweights.request_id) you can cite and later report on.
