Maxwell Directory (x402 + MCP) is answering right now. Last checked 11 min ago. 93 installs a week from npm. It exposes 36 tools.
Local providers worldwide, plus travel and public data. Free search; paid answers via x402.
Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 1 October 2026. No other catalogue keeps this.
Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.
Endpoint below is the one we actually reach during checks — not the one copied from a README. Last verified 11 min ago.

This one needs environment variables set before it will start:

The author declared them in the registry entry; get the values from the project itself.
Read directly from the server with tools/list, grouped by what they act on.
