# Claude Toolkit: Skills, plugins and MCP connectors

Checked 2026-10-18. Independent picks, not paid placements.

- **Skills:** Folders of written instructions, plus optional scripts and files, that Claude loads only when a task needs them. Use one when you want Claude to follow your process every time, like your report format or contract checklist.
- **Plugins:** Installable packages that bundle skills, connectors, commands and agents into one add-on. They work in Claude chat, Cowork and Claude Code, and can be shared across a team.
- **MCP connectors:** MCP (Model Context Protocol) is an open standard for connecting AI to outside tools and data. A connector links Claude to a service so it can read from it and take actions in it.
