Get metadata for a specific shadcn/ui v4 component
AI agents call get_component_metadata to retrieve information from Shadcn Ui without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about UI components from the shadcn/ui library. It performs a read-only query operation with no capability to modify, delete, execute code, or affect financial systems. The blast radius of misuse is minimal—at worst, an agent could retrieve metadata it shouldn't have access to, but cannot cause damage with the returned information alone.
From the tool's definition Tool name 'get_component_metadata' and description 'Get metadata for a specific shadcn/ui v4 component' indicate a retrieval operation.
Documented attack patterns abuse exactly the kind of access get_component_metadata gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Shadcn Ui, and nothing reaches the server without passing your rules. This is the rule we recommend for get_component_metadata:
{
"version": "1",
"default": "deny",
"tools": {
"get_component_metadata": {}
}
}get_component_metadata is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get metadata for a specific shadcn/ui v4 component. It is categorised as a Read tool in the Shadcn Ui MCP Server, which means it retrieves data without modifying state.
Register the Shadcn Ui MCP server in PolicyLayer and add a rule for get_component_metadata: 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 Shadcn Ui. Nothing to install.
get_component_metadata 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 get_component_metadata 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 get_component_metadata. 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.
get_component_metadata is provided by the Shadcn Ui MCP server (jpisnice/shadcn-ui-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Shadcn Ui, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
