Specialized graphics card (VGA) search tool. Find GPUs by chipset model, VRAM capacity, and price. Perfect for gaming builds, content creation, or AI workloads.
AI agents call search_gpu to retrieve information from CoolPC MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries product data from a price database without modifying, executing external operations, or deleting anything. It has no side effects beyond returning search results. This is a classic Read operation. The blast radius of misuse is minimal—an AI agent could only retrieve more product information than intended, with no irreversible consequences.
From the tool's definition The tool is described as a search tool that finds GPUs by chipset model, VRAM capacity, and price. The verb 'search' combined with 'find' and the purpose of helping users query component prices indicates a retrieval operation.
Documented attack patterns abuse exactly the kind of access search_gpu gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and CoolPC MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search_gpu:
{
"version": "1",
"default": "deny",
"tools": {
"search_gpu": {}
}
}search_gpu is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Specialized graphics card (VGA) search tool. Find GPUs by chipset model, VRAM capacity, and price. Perfect for gaming builds, content creation, or AI workloads. It is categorised as a Read tool in the CoolPC MCP Server MCP Server, which means it retrieves data without modifying state.
Register the CoolPC MCP Server MCP server in PolicyLayer and add a rule for search_gpu: 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 CoolPC MCP Server. Nothing to install.
search_gpu 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_gpu 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_gpu. 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_gpu is provided by the CoolPC MCP Server MCP server (shyuan/coolpc-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from CoolPC MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
