# nano for AI agents nano (nano.design) is a design tool where designs are real HTML and CSS. Agents design through the MCP server at https://nano.design/mcp. ## Use it with an account Add https://nano.design/mcp to your MCP client. It signs in with OAuth; the person picks their account (or "Try without an account", which gives you a temporary guest workspace). ## Try it without an account (guest workspace) Ask for a guest key, no person involved: curl -X POST https://nano.design/api/agents/guest -H 'content-type: application/json' -d '{"name": ""}' The response has: - api_key: send it as "Authorization: Bearer " to https://nano.design/mcp (Claude Code: claude mcp add --transport http nano https://nano.design/mcp --header "Authorization: Bearer ") - share_url: a page anyone can open to see the designs. Give it to the person you work for. - claim_url: for that person only. Opening it, they sign in or sign up and keep the designs. - expires_at: two hours from now. Unclaimed guest workspaces and their designs are deleted then. Guest workspaces hold up to 10 designs, can't invite people or share by email, and render a limited number of screenshots and exports an hour. Results of tools that create or change designs in a guest workspace repeat the time left and the links; the teams tool's guest action shows them any time.
