AISkills402 is answering right now. Last checked 2 min ago. It exposes 4 tools.
Tested AI agent skill files (SKILL.md), bought once over x402 for cents on Base. Free MCP search.
Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 27 August 2026. No other catalogue keeps this.
A tool that vanishes takes a piece of your agent with it, and the change arrives silently. Watch this server and every such change lands in your inbox.
