Questions

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 gets 402 and a PAYMENT-REQUIRED challenge; retry with the PAYMENT-SIGNATURE header.

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.
