Skillselion
Skillselion is a free, web-based directory that aggregates and ranks coding-agent skills, MCP servers, and marketplaces, primarily for Claude Code but also for Codex and Cursor. It indexes over 58,768 skills as of August 15, 2026, and is updated automatically daily, ranked by real install counts. The site provides structured browsing by category (AI & Agents, Frontend & Design, Backend & Data, Dev Tools, Automation, Testing & Review, Security, Monitoring & Cloud, Docs & Planning) and by type (Skills, Marketplaces, MCP servers). Each entry includes publisher information, GitHub star counts, and install counts, helping users assess trust and popularity. A search function and trending section highlight recent shifts in adoption. Skillselion also offers a Model Context Protocol (MCP) server named skillselion-mcp, which allows AI agents to query the directory programmatically via npm/npx. This makes the directory not only a browser-based reference but also a data source for agent workflows. Pricing is free, and no account is required for browsing.
