## What it does

AISkills402 sells tested AI agent skill files \(SKILL.md, Agent Skills format\). This free MCP server lets an agent search the catalog \(search\_skills, list\_categories\), read a skill's details and test results \(get\_skill\) and re-download a file it already owns \(redownload\_skill\). A skill file is bought once over the x402 protocol, in USDC on Base mainnet, for cents: no account and no API key, and new versions of an owned skill are free.
