open-design is a Claude Code marketplace that installs a stdio MCP server exposing a local Open Design app (projects, files, preview, 139 skills) to coding agents.
About
open-design is nexu-io's Claude Code marketplace that installs one Open Design plugin, a stdio MCP server backed by a local `od` daemon. It lets a coding agent list design projects, manipulate files, preview work, and call a bundled catalog of 139 skills while the design app and files stay on the local machine. A developer uses it when design and front-end implementation need to share one local source of truth instead of a Figma-first or cloud-upload workflow. It matters because the agent can act on real design state on disk rather than screenshots or exported assets.
- Single Open Design plugin exposing a stdio MCP server
- Bundles a catalog of 139 skills
- Local-first: design app and files stay on disk
- Requires the `od` daemon on PATH (brew / npm / DMG)

FAQ
Who is Open Design for?
It is for developers running nexu-io’s Open Design app locally who want agent access via MCP and a large bundled skill library.
When should I use Open Design?
Use it when UI work spans a local design tool and your codebase and you need previews, files, and agent skills in one install.
How do I add Open Design to my agent?
Install od on PATH, then add the nexu-io/Open Design marketplace plugin with your agent’s plugin command so the stdio MCP server starts with sessions.
