Common questions
Is Trailweights MCP safe?
It passed 3 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
You need to fill in: x-trailweights-key
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed 19 days ago, and the latest version (0.5.0) reached the registry 31 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.
What can I use instead?

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:— or —Authorization: Bearer
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.
