Implementation Reference

• src/send-tools.ts:22-41 (handler)

  The handler logic for the 'send_email' tool, which validates the tool name and uses nodemailer to send the email.

    if (toolName !== "send_email") {
      return { content: [{ type: "text" as const, text: `Unknown tool: ${toolName}` }], isError: true };
    }
    try {
      const { to, subject, body } = args as { to: string; subject: string; body: string };
      const transporter = nodemailer.createTransport({
        host: smtpConfig.host,
        port: smtpConfig.port,
        secure: true,
        auth: { user: smtpConfig.user, pass: smtpConfig.password },
      });
      await transporter.sendMail({ from: smtpConfig.user, to, subject, text: body });
      return {
        content: [{ type: "text" as const, text: `이메일 발송 완료: "${subject}" → ${to}` }],
      };
    } catch (error) {
      const msg = error instanceof Error ? error.message : String(error);
      return { content: [{ type: "text" as const, text: `발송 오류: ${msg}` }], isError: true };
    }
  };

• src/send-tools.ts:5-17 (schema)

  The schema definition for the 'send_email' tool, specifying input arguments.

  {
    name: "send_email",
    description: "이메일을 발송합니다.",
    inputSchema: {
      type: "object" as const,
      properties: {
        to: { type: "string", description: "수신자 이메일 주소" },
        subject: { type: "string", description: "제목" },
        body: { type: "string", description: "본문 (텍스트)" },
      },
      required: ["to", "subject", "body"],
    },
  },
