MCP

Every registry item carries agent-facing metadata: a one-line summary, when to use it, when not to, props, pitfalls, accessibility notes and examples. The Fujin MCP server serves it in layers so an agent only pays for what it reads.

Tool	Returns	Typical size
`list_items`	Name, type and summary for every item	~35 tokens per item
`get_item`	Full guidance for one item, no source	a few hundred tokens
`get_item_source`	The files that would be installed	full source
`search_items`	Ranked matches for a query	small
`get_install_command`	Exact command, including dependencies	one line

Setup

npx fujin mcp init --client claude

Or add it by hand:

.mcp.json

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

The shadcn MCP server (npx shadcn@latest mcp) also works: it reads the same registry, and the metadata is included in every item under meta.fujin.
