Search for components by name or category
AI agents call search_components to retrieve information from Basecoat UI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a search/query operation to retrieve component information. It has no side effects, does not execute code or commands, does not modify data, and does not delete or move resources. The blast radius of misuse is minimal—an AI agent could only retrieve component documentation, which is the intended use case. This is a straightforward Read category tool.
From the tool's definition Tool name 'search_components' and description 'Search for components by name or category' indicate a query operation that retrieves component data without modifying, executing, or destructively acting upon resources.
Documented attack patterns abuse exactly the kind of access search_components gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Basecoat UI MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search_components:
{
"version": "1",
"default": "deny",
"tools": {
"search_components": {}
}
}search_components is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search for components by name or category. It is categorised as a Read tool in the Basecoat UI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Basecoat UI MCP Server MCP server in PolicyLayer and add a rule for search_components: 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 Basecoat UI MCP Server. Nothing to install.
search_components 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 search_components 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 search_components. 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.
search_components is provided by the Basecoat UI MCP Server MCP server (sorbh/basecoat-ui-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Basecoat UI MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
