AISkills402
by @Georgi Kalchev
GitHubRemote MCP server (Streamable HTTP, no account, no API key) for AISkills402, a catalog of tested AI agent skill files (SKILL.md, Agent Skills format). Tools, all free: search_skills (search by plain-language query, category, tag or language; each card says what the skill is for, its price and how it was tested with a strong and a weak model), list_categories, get_skill (one card plus the exact x402 payment requirements for its file) and redownload_skill. The server never takes payments: the file itself is bought once over x402 for cents in USDC on Base, and re-downloads and new versions are free.
Install
claude mcp add --transport http aiskills402 https://mcp.aiskills402.com/mcpHosted server
https://mcp.aiskills402.com/mcpThis server runs hosted, so there is no local process to install. The command above adds it to Claude Code, and the client configs below connect Claude Desktop, Cursor, and VS Code straight to the hosted endpoint. Any sign-in the server needs happens when you first connect.
Install with your client
claude mcp add --transport http aiskills402 https://mcp.aiskills402.com/mcp
Run this in a terminal to add the server to Claude Code.
What this does
AISkills402 exposes a set of tools to Claude over the Model Context Protocol. It runs as a hosted server, so once you add it with the command above, those tools become callable inside any conversation, with nothing running on your machine.
