Anlyon alternative
Run the operations that matter as governed actions.
Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.
Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

Why it is in this group
- The name "get_block" says "get": a word for reading.
What it can reach
- private-dataThe description's first sentence says "get" and "file": it reads files.
Description, as the server wrote it Get one block's details by its id from search_blocks: what it is, its install command, the npm packages and registry items it depends on, the files it adds, and its registry's notes on using it. Set include_source to also get its source code, for when the user wants to read or adapt the code rather than install it.

Why it is in this group
- The name "search_blocks" says "search": a word for reading.
What it can reach
- private-dataThe description's first sentence says "search" and "table": it reads databases.
Description, as the server wrote it Search the shadcn/ui blocks listed on shadcn.exchange: ready-made sections of a page, such as heroes, pricing tables, login forms, dashboards, footers and FAQs, from every public shadcn registry, free and paid. Use it when the user is building a page or a screen with shadcn/ui and wants a section to start from, or asks what blocks exist for something. Results come best first. Each has its id (for get_block), its description, its install command if it is free or where to buy it if it is paid, and its page with a live preview. Every word of the query has to be in a block's name, title, description or registry, so use one or two words, and the category for the kind of section.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
Exfil surface
Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.
No private-data, untrusted-input, outbound path in this server alone: no tool is tagged untrusted-input or outbound.
- Reads private data2
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write0
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- Can send data out0
- Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.
Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.
Findings
Matches of fixed checks, with the text they matched.
No check matched anything in these tool definitions. That is not a safety guarantee.
History
Changes to its tool definitions and to its remote endpoint, newest first.
No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.
Install
Pinned to version 1.0.0. Values in angle brackets are yours to fill in.
claude mcp add --transport http blocks https://shadcn.exchange/mcpclaude mcp add --transport http blocks https://shadcn.exchange/mcpRun in a terminal.
Claude Code permissions
Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.
{
"permissions": {
"allow": [
"mcp__blocks__search_blocks",
"mcp__blocks__get_block",
"mcp__blocks__list_categories",
"mcp__blocks__list_registries"
],
"ask": [],
"deny": []
}
}Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as blocks. Review it before you use it.

Pin
Keep the decision: fail CI when the tools change, follow every change, or show a badge.
Pin in CI
Fail a build when the tools you reviewed are not the tools the server serves today.
