Pay-per-call MCP tools and signed on-chain attestations: 20 free/day, then x402 or a spend key.
Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 10 October 2026. No other catalogue keeps this.
Today is the operative word: we check xytara MCP Executor every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
