TrailWeights MCP Server
Model Context Protocol server for the TrailWeights ultralight gear corpus: verified product weights, canonical specs, creator video reviews with timestamps, pre-scored field consensus, and in-house pack templates. 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 request. Anonymous calls get 401.
x-trailweights-key: <key>— or —Authorization: Bearer <key>

500 tool calls per day (resets 00:00 UTC), 60 requests per minute. Past
the daily cap the server answers 429 with Retry-After. Prepaid credit
packs and per-call payment (x402 on Base, Stripe MPP) are listed on the same
page; 402 responses carry the payment challenge when a key is out of
allowance.
Rate-limit headers (x-ratelimit-limit, x-ratelimit-remaining,
x-ratelimit-reset) ride every response.
