  Implementation of the proxy_get_ca_cert tool handler, which fetches the certificate from proxyManager and returns the PEM and/or fingerprint.

  server.tool(
    "proxy_get_ca_cert",
    "Get the CA certificate PEM and SPKI fingerprint for installing on the target device.",
    {
      format: z.enum(["pem", "fingerprint", "both"]).optional().default("both")
        .describe("What to return: 'pem', 'fingerprint', or 'both'"),
    },
    async ({ format }) => {
      const cert = proxyManager.getCert();
      if (!cert) {
        return { content: [{ type: "text", text: JSON.stringify({ status: "error", error: "No certificate. Start the proxy first." }) }] };
      }
  
      const result: Record<string, unknown> = { status: "success" };
      if (format === "pem" || format === "both") {
        result.certPem = cert.cert;
      }
      if (format === "fingerprint" || format === "both") {
        result.fingerprint = cert.fingerprint;
      }
      result.instructions = "Save the PEM to a .crt file, transfer to device, and install as trusted CA.";
  
      return { content: [{ type: "text", text: JSON.stringify(result) }] };
    },
  );
