Claude Skills Marketplace
Beyond building your own skills, five community platforms let you discover, browse, and install thousands of ready-made skills and MCP tools for Claude Code and other AI agents — from AI-graded curated directories to million-skill GitHub indexes and MCP marketplaces with managed auth.
Curated, AI-rated skills with S/A/B ranking. CLI install, desktop app, and Skill Stacks.
Community-aggregated skills from GitHub. Occupation-based filtering and a public REST API.
Primarily an MCP marketplace with a growing skills section. One-command CLI setup.
SkillHub is a curated skills directory where every skill is graded by AI across five dimensions: Practicality, Clarity, Automation, Quality, and Impact. S-rank skills (9.0+) are the best of the best. You can browse by category (Development, Frontend, Backend, Data, AI/ML), search semantically, or install via the CLI in one command.
Install any skill with one command using the SkillHub CLI:
SkillHub also offers Skill Stacks — pre-configured bundles for specific workflows. Examples include the Solopreneur Toolkit (9 skills for SEO, social media, and market research),The Startup CEO Stack (27 skills covering planning to deployment), and anAcademic Research Suite. Pro members can download full stacks; all are previewable for free.
SkillsMP aggregates over 1.1 million skills from public GitHub repositories. It's the largest collection available and indexes skills compatible with Claude Code, OpenAI Codex CLI, and other tools that support the open SKILL.md standard. You can browse by occupation (23 major groups, 867 SOC categories) or by use-case category, and a public REST API lets you query the catalogue programmatically.
SkillsMP does not have a dedicated CLI — you find the skill, clone the repository, and copy the skill folder into your skills directory:
Smithery is primarily an MCP (Model Context Protocol) marketplace — 7,887+ servers covering tools like GitHub, Notion, Supabase, Slack, and Google Sheets. It also has a growing Skills section. What makes Smithery different is its auth handling: install a tool once and Smithery manages OAuth, credential injection, and retries across Claude, GPT, and other agents automatically.
Set up Smithery's CLI and add an MCP to Claude in two commands:
More MCP directories
If you need to browse MCP servers beyond what Smithery lists, two more community directories cover a wider catalogue. Neither hosts Claude SKILL.md skills directly, but both are useful when hunting for tool integrations.
A community-run MCP discovery site with 20,617+ servers. Supports filtering by featured, hosted, and official servers. No CLI — browse and copy configs manually. Includes a playground for testing servers in the browser.
An all-in-one AI workspace with the largest MCP directory (22,695+ servers). Each entry gets A/B/C/D quality grades across licence, code quality, and maintenance. Also offers MCP hosting, an API gateway, and a remote MCP connector.
