SuperSkill Registry is a Model Context Protocol (MCP) server: Find, inspect and install reviewed reusable AI-agent capabilities from superskill.sh. In practice that means any MCP-compatible AI assistant can call SuperSkill Registry's tools directly — the model decides when to use them in a conversation or agent run.
It's a hosted (remote) server — point your client at https://superskill.sh/mcp and you're connected, with nothing to install locally. The current release is v0.3.1, with source at elvismusli/onlyharness on GitHub.
SuperSkill Registry is listed under AI & Agents on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
