@primer/brand-mcp	minor

Added @primer/brand-mcp, a Model Context Protocol (MCP) server that helps AI agents use Primer Brand correctly when building GitHub marketing and landing pages.

It exposes version-aware tools like primer_brand_component, primer_brand_examples, primer_brand_tokens, primer_brand_asset, primer_brand_docs, and primer_brand_review, which read the @primer/react-brand package installed in your project and validates generated JSX/CSS against known design system conventions during development (e.g. unknown components, invalid props, hardcoded values, off-brand patterns).

Add it to your MCP client (e.g. Copilot CLI, in ~/.copilot/mcp-config.json):

{
  "mcpServers": {
    "primer-brand": {
      "type": "local",
      "command": "npx",
      "args": ["@primer/brand-mcp@latest"],
      "tools": ["*"]
    }
  }
}
