Skillselion is the #1 directory of Claude Code, Codex, and Cursor skills, marketplaces, and MCP servers, ranked by real install counts instead of self-reported stats.
What is Skillselion?
Skillselion is a free, searchable directory of 58,800+ agent skills, 12,600+ plugin marketplaces, and 8,400+ MCP servers for AI coding agents. You enter a tooling need — such as frontend design or web scraping — and it returns ranked listings with install counts, star counts, and one-command install commands. It runs in the browser with no account required, and is an independent project not affiliated with Anthropic, OpenAI, or Cursor.

FAQ
Answers to the most frequent questions about Skillselion’s cost, compatibility, and listing methodology.
Is Skillselion free?
Yes. All browsing, search, leaderboards, guides, and the weekly brief are free, and you don’t need an account to use the directory.
Does Skillselion work with Codex and Cursor?
Yes. While it is known for Claude Code skills, the directory also covers Codex and Cursor skills, marketplaces, and MCP servers, plus other coding agents.
How are listings ranked?
