DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.
The built-in claude_design first-party MCP server (https://api.anthropic.com/v1/design/mcp) has been removed from the auto-provisioned server list. Users relying on Claude Design should ensure it is configured via their MCP settings or the /design login flow, which routes through the updated hub command rather than a built-in server entry.
