The free Skills & MCP library for Claude, OpenClaw and Hermes
MCP (Model Context Protocol) is the open standard that lets AI agents — Claude, Claude Code, OpenClaw, Hermes, Cursor, Windsurf — connect to external tools, databases and APIs through a single uniform interface. An MCP server wraps a tool so any compliant AI agent can call it with zero custom integration code.
An AI Skill is a reusable instruction bundle: a name, the trigger phrases that surface it, and the steps your agent follows. Skills turn one-off prompts into reliable, repeatable workflows.
This library is 100% free. Every Skill and MCP server has its own dedicated page with description, install info and source links. Filter by the AI agent you use, the category of work you're automating, or the specific tool you want to connect.
