<h3>Discover Agent Skills, MCP Servers, and AI Tools</h3>
Skills Agentes is an independent directory focused on Agent Skills and MCP servers, designed to help you find, understand, and install the tools your AI agents need. We are not affiliated with Anthropic, OpenAI, or any other listed providers.

<h4>What are Agent Skills?</h4>
An Agent Skill is essentially a SKILL.md file, which is a markdown document containing instructions that your AI agent reads to perform a specific task. It's not a plugin or a binary, meaning the same files work across different agents like Claude Code, Cursor, or Codex – the only difference is where these files end up on your system.

<h4>How to Install a Skill</h4>
Each skill listing provides a ready-to-copy installation command. This command includes the correct variant for your specific agent and the scope you choose – whether it's just for the current project or for your entire machine. Simply copy the command, paste it into your terminal, and the agent will place the files in the appropriate directory.

<h4>Key Features:</h4>
<ul>
 <li>Comprehensive Directory: Browse and discover a wide range of Agent Skills and MCP servers.</li>
 <li>Categorization: Easily find tools by category, including Development Tools, Testing &amp; QA, DevOps &amp; Infrastructure, Security, Data &amp; Analytics, and more.</li>
 <li>Agent Compatibility: Skills are designed to work with popular agents such as Claude Code, Claude, Cursor, GitHub Copilot, Codex, Windsurf, and Gemini.</li>
 <li>Installation Convenience: Install skills with a single command, making integration seamless.</li>
 <li>Community Driven: See rankings based on installations to understand what the community is using.</li>
 <li>Featured Skills: Explore curated lists of proven and recommended skills.</li>
 <li>MCP Servers: Connect your agent to external processes for enhanced capabilities like database access, API calls, or browser interaction.</li>
</ul>

<h4>Free to Use</h4>
Searching, comparing, and installing skills from our directory is completely free. The skills we index are from public repositories with their own licenses. Any paid listings are clearly marked as featured or sponsored.

<h4>MCP Servers Explained</h4>
While a skill is a file that instructs an agent, an MCP (Machine Control Protocol) server is a running process that provides tools and services to the agent. This could include reading databases, calling APIs, or controlling a web browser. You can find a list of indexed MCP servers in the dedicated section.

<h4>Adding Your Skill</h4>
You can submit your own skills by providing the GitHub repository URL via the submission page. We automatically index the SKILL.md file, classify it, and keep the listing updated as your repository changes.

Hey I’m a solo developer and recently launched <a target="_blank" rel="noopener noreferrer nofollow" class="text-green-500 rich-link break-all link-break" href="http://aiselfi.es">aiselfi.es</a>, an app that turns your selfies into professional-looking photos in just a few clicks.Here’s how it works: You upload a couple of selfies, and the AI (powered by the latest Flux model) generates a variety of profile pictures you can use for your social media accounts, dating apps, or even your professional LinkedIn profile.The idea is to save you time and effort by using AI to make your photos look like they were taken by a pro.I built this for two reasons:- Save time on photo shoots or expensive professional photos – Now anyone can get high-quality profile pictures without needing fancy equipment or photographers. - Personalized AI output – The AI understands different facial expressions and styles, creating a diverse set of images that represent who you are in different ways. Whether you want something more professional, casual, or even creative, you’ll have options to choose from.I’d love feedback on how to improve the service or any features you’d want to see in the future. Let me know if you give it a try!Cheers, Jonathan
