# Knapsack

> Knapsack delivers your design system to Claude Code, Cursor, and VS Code over the Model Context Protocol (MCP), and shows you what each agent received.

Agents start at https://knapsack.sh/agents.md: what Knapsack is, how to install its MCP servers, and how to get your person signed up. Knapsack is in public beta.

## MCP servers

- [A workspace's context](https://knapsack.sh/agents.md): `https://knapsack.sh/mcp/workspace/{workspaceId}`, the URL to give a coding agent. Seven tools over one workspace's design system (describe_context, search_context, read_context, check_usage, render_ui, remember, which proposes a memory, and send_feedback, which files feedback with Knapsack; those two write), the build-ui prompt, and the entities as resources. Streamable HTTP, OAuth sign-in or a workspace API key.
- [Setup](https://knapsack.sh/agents.md): `https://knapsack.sh/mcp/manage` creates and manages organizations, workspaces, attachments, invitations, teams and tags as the signed-in person, one tool per API operation. It reads no design system context. Streamable HTTP, OAuth sign-in or a workspace API key. A key is scoped to its own workspace and reaches the tools whose operations accept one, among them listMyWorkspaces, its attachments and their sync jobs, its keys, its memories, and the tags on its attachments, delivery and memories.

## Agents

- [agents.md](https://knapsack.sh/agents.md): install, sign up with OAuth or Agent Auth, and API keys
- [The Knapsack skill](https://knapsack.sh/.well-known/skills/knapsack/SKILL.md): connect, then build UI with the design system
