An MCP server (Model Context Protocol server) is the standard way to give Claude Code access to external tools, data sources, and APIs without baking the connection logic into a prompt. MCP was open-sourced by Anthropic in late 2024 and has become the dominant integration substrate for Claude Code agents — thousands of public servers now exist for GitHub, Slack, Postgres, Filesystem, Notion, Linear, browser automation, and almost every SaaS API.
ClaudSkills indexes the skills layer on top of that ecosystem: SKILL.md files that wrap MCP servers into invokable, named workflows for Claude Code. Where a raw MCP server gives Claude tools to call, a skill tells Claude how to use those tools for a specific task. This page lists every skill in our catalog that integrates with one or more MCP servers, ranked by quality.
If you're new to MCP entirely, start with the SKILL.md primer and Anthropic's MCP specification. Otherwise, browse below — every entry has a one-paste install command and links to the source repository.
