All tools are organized into categories based on their primary function. From MCP servers that extend AI coding agents to prompt libraries and full agent frameworks, find exactly what you need.
MCP Server — Model Context Protocol servers for AI agents
Claude Skill — Skills and plugins for Anthropic Claude
Explore curated collections of the best tools for common AI agent workflows. Each scenario page ranks tools by quality score, stars, and community activity to help you find the right solution for your use case.
AgentSkillsHub indexes over 55,000 open-source repositories across MCP servers, Claude skills, Codex skills, AI coding assistants, and agent tools. Every project is scored on 10 weighted signals including GitHub stars, code quality, documentation, and community activity. Data refreshes every 8 hours so you always see the latest tools.
Quality Scoring
Each tool receives a composite quality score from 0 to 100 based on six dimensions: completeness, clarity, specificity, examples, README structure, and agent readiness. This helps developers quickly identify production-ready tools versus experimental projects.
Compare and Discover
Use the Compare feature to evaluate multiple tools side by side. The Skill Analyzer provides security grades and platform compatibility checks, helping teams make informed decisions about which open-source AI tools to adopt.
How It Works
Agent Skills Hub automatically discovers AI agent tools from GitHub using multi-phase data collection. Each repository goes through search, enrichment, README analysis, and quality scoring. Our system tracks stars, forks, commit frequency, open issues, documentation quality, and community engagement to produce a single composite score. New tools appear within hours of being published. Developers can browse by category, search by keyword, filter by programming language, or explore curated scenario pages like browser automation, code review, and database management.
Stay Updated

Each issue features the top new tools of the week, star velocity rankings, and curated recommendations across all categories.
About the Editor
AgentSkillsHub is built and maintained by Jason Zhu (@GoSailGlobal), an independent researcher tracking open-source AI agent ecosystems since 2024. Jason is also the author of the Blue Book of Agent Skills 2026, an in-depth analysis of the Claude Skills / MCP / Codex ecosystem published openly on GitHub.
The Hub runs as a solo project, designed to be transparent and reproducible: every scoring dimension is documented, every data snapshot is archived, and the entire source code is open under MIT on GitHub. The goal is not to rank skills by popularity alone, but to help developers find tools that are actually production-ready.
Editorial Methodology
Every indexed repository passes through a 6-phase pipeline running every 8 hours: GitHub search → metadata enrichment → README fetch → quality scoring (10 weighted dimensions) → category classification → composability analysis. No manual curation is applied to ranking — signals are purely data-driven to avoid editorial bias.
Daily reports of new skills and weekly trending lists are selected according to transparent rules documented in the repository. When human judgement is needed (such as for "Verified Creator" decisions), the reasoning and criteria are written down publicly, not hidden behind a pay-for-placement system.
