shadcn-ui-mcp-server is a Model Context Protocol service that gives AI coding assistants structured information about shadcn/ui components, including their source code, examples, blocks, metadata, and installation details. It supports implementations for React, Svelte, Vue, and React Native so agents can use the library during development.
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.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00020 | $0.00092 |
| Opus 5.5 | $0.00008 | $0.00037 |
| Sonnet 5.5 | $0.00004 | $0.00018 |
| Haiku 4.5 | $0.00002 | $0.00009 |
Grade A, and why
shadcn-ui-mcp 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 12d ago.
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.

shadcn-ui-mcp is a skill published in the GitHub repository Jpisnice/shadcn-ui-mcp-server (3,055 stars, last pushed 13d ago), licensed MIT. It adds 20 tokens to every session and 92 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings.
