Storybook MCP Addon — questions

Answers built from our own checks of this server.

Why is there no uptime for Storybook MCP Addon?
Storybook MCP Addon runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @storybook/addon-mcp was installed 1 753 385 times last week.
How do I connect Storybook MCP Addon?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls @storybook/addon-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Storybook MCP Addon?
The npm package @storybook/addon-mcp was installed 1 753 385 times in the last week. Week over week that is +7%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Storybook MCP Addon open source?
Yes — it is published under the MIT licence, written in TypeScript, 265 stars on GitHub and 29 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
