Implementation Reference

• src/tools/system.ts:45-52 (handler)

  The handler function for 'get_cpu_temp' tool that executes an RPC call to 'CpuTemp.getStats' and returns the CPU temperature readings as JSON. Handles errors and returns appropriate error messages.

  async () => {
    try {
      const result = await client.rpc("CpuTemp", "getStats", {});
      return toolResult(JSON.stringify(result, null, 2));
    } catch (error) {
      return toolResult(`Error fetching CPU temperature: ${error}`, true);
    }
  },

• src/tools/system.ts:41-53 (registration)

  Tool registration for 'get_cpu_temp' using server.tool() method. Defines the tool name, description, empty input schema (no parameters), and the handler function.

  server.tool(
    "get_cpu_temp",
    "Get CPU temperature readings from OpenMediaVault",
    {},
    async () => {
      try {
        const result = await client.rpc("CpuTemp", "getStats", {});
        return toolResult(JSON.stringify(result, null, 2));
      } catch (error) {
        return toolResult(`Error fetching CPU temperature: ${error}`, true);
      }
    },
  );

• src/tools/system.ts:5-7 (helper)

  Helper function that formats tool results into the expected MCP response format with content array and optional error flag.

  function toolResult(text: string, isError = false) {
    return { content: [{ type: "text" as const, text }], isError };
  }
