Searches Magic UI registry items by keyword or use case.
AI agents call searchRegistryItems to retrieve information from Magic UI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward search/query operation that retrieves data from a registry. It has no side effects—it does not create, modify, delete, or execute code. The search returns registry items for browsing and selection purposes. The low severity reflects minimal blast radius: even if an AI agent misuses a search, it can only retrieve available UI component information, which is already public registry data.
From the tool's definition Tool searches Magic UI registry items by keyword or use case; described as a search operation that retrieves matching registry entries without modifying or executing them.
Documented attack patterns abuse exactly the kind of access searchRegistryItems gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Magic UI MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for searchRegistryItems:
{
"version": "1",
"default": "deny",
"tools": {
"searchRegistryItems": {}
}
}searchRegistryItems is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Searches Magic UI registry items by keyword or use case. It is categorised as a Read tool in the Magic UI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Magic UI MCP Server MCP server in PolicyLayer and add a rule for searchRegistryItems: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Magic UI MCP Server. Nothing to install.
searchRegistryItems is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the searchRegistryItems rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for searchRegistryItems. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
searchRegistryItems is provided by the Magic UI MCP Server MCP server (magicuidesign/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Magic UI MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
