Nostalgiaui

@nostalgiaui/mcp

An MCP server that gives AI coding agents NostalgiaUI's eras, palettes, component source and contrast checks, so an agent asked for a settings page in Frutiger Aero with the Nord palette can get the real tokens rather than guess.

Tools: list_eras, list_palettes, get_tokens, get_component, import_vscode_theme, check_contrast.

In claude_desktop_config.json:

{

"mcpServers": { "nostalgiaui": { "command": "npx", "args": ["-y", "@nostalgiaui/mcp"] } } }

get_component returns more than source: the import line, the era-specific CSS, a props table for each part extracted from the TypeScript types, and the component's structured doc. The doc covers anatomy, patterns, do and don't pairs, accessibility, extensibility, notes for the requested era, and notes naming what is easy to get wrong. Pass section, for example accessibility, to receive only that part. The rules every component shares, such as rendering inside NostalgiaRoot, are sent once as the server's instructions rather than repeated in each answer.
