# Library > Library is the design context layer for humans and agents. Document your components, tokens, and patterns in one place, publish them to a public URL, and let your AI editor read from the same source — over MCP. Library exposes every workspace as both a published site (read by humans) and an MCP server (read and written by agents). Same source, two surfaces. ## Pages - [Home](https://www.library.guide/index.md): What Library is — context that stays current from Figma and code, a published site, AI chat, and MCP integration with Claude, Cursor, v0, and more. - [How to use Library](https://www.library.guide/how-to-use.md): Complete guide — workspaces, folders and pages, documenting manually or with an AI agent, publishing, MCP setup, agent rules, linting against the system, and CI integration. ## Full content - [llms-full.txt](https://www.library.guide/llms-full.txt): All page content concatenated as a single markdown document. ## Product - App: https://app.library.guide - MCP endpoint: https://mcp.library.guide/ - Library plugin for Figma: https://www.figma.com/community/plugin/1539555100619791974/library-plugin-for-styles-variables-components
