Get demo code illustrating how a shadcn/ui v4 component should be used
AI agents call get_component_demo 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 and queries demo code for UI components, which is a read-only operation with no side effects. It does not create, modify, delete, or execute anything—it only provides documentation/example information to inform the user about component usage.
From the tool's definition Tool name 'get_component_demo' and description 'Get demo code illustrating how a shadcn/ui v4 component should be used' indicate retrieval of existing demo/documentation content with no modifications to system state.
Documented attack patterns abuse exactly the kind of access get_component_demo 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_demo:
{
"version": "1",
"default": "deny",
"tools": {
"get_component_demo": {}
}
}get_component_demo is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get demo code illustrating how a shadcn/ui v4 component should be used. 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_demo: 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_demo 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_demo 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_demo. 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_demo 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.
