CPU-Z MCP POC

A small Model Context Protocol server that reads the current machine's CPU, memory, and disk information. It runs over stdio, so it can be used from the MCP Inspector or any MCP-compatible client.

Requirements

• Node.js 24.20.0 or newer

• pnpm 10.17.1 or newer

Related MCP server: mcp-system-info

Install

pnpm install

Run it

Start the MCP server directly:

pnpm mcp:serve

The server waits for an MCP client over stdin/stdout. To explore it through a visual interface, use the MCP Inspector:

pnpm mcp:inspect

mcp:inspect starts the server and opens the MCP Inspector, a small web UI for connecting to the server and trying its MCP capabilities without configuring another client. In the Inspector:

1. Connect to the server started by the command.

2. Open Tools and run cpu-info_finder, memory-info_finder, or disk-info_finder.

3. Open Resources and read cpu://info for structured CPU data.

4. Open Prompts, choose computer-purpose-upgrade, and set purpose to gaming, home_office, or video_editor.

Use from an MCP client

Add the server to an MCP client's configuration. Use an absolute path to this repository:

{
  "mcpServers": {
    "cpu-z": {
      "command": "node",
      "args": ["/absolute/path/to/my-cpu-z-mcp-poc/src/app/mcp/server.ts"]
    }
  }
}

Restart the client, then ask it to inspect the computer. For example:

Check my CPU, memory, and disk usage, then tell me whether this computer is ready for home office work.
