Superstables MCP indexes 2,300+ payable x402/MPP/ACP services, probes a third that are dead
lowkeyfranco · reddit · 2026-09-17
A developer launched Superstables, an MCP server for discovering services AI agents can actually pay for:
- Offers findservices, getservice, and getstats endpoints backed by an index of 2,300+ x402/MPP/ACP payable services, with no auth required.
- The hard part wasn't listing but liveness probing: roughly a third of "payable" services listed across sources no longer respond.
- Every entry is probed on a rolling schedule, so the API returns what's live now, not stale submissions.
- The author is asking how others handle dead listings in their own directories.
