What is shadcnui-jpisnice-react?

A local MCP server that gives an AI assistant access to shadcn/ui components, examples, reusable page sections, and metadata for React. MCP is a standard way for tools to provide information to AI assistants.

Use it to look up shadcn/ui React component code, demos, and blocks; it requires a GitHub access token.

It avoids manually searching component source and examples while building a React interface.

shadcnui-jpisnice-react — MCP server for Cursor by blockmatic

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/blockmatic/basilic

Made for: Cursor.

Security

Grade A, and why

shadcnui-jpisnice-react scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
