• src/index.ts:361-411 (handler)

  The handler function that executes the send_email tool: destructures args, builds raw MIME email, base64url encodes it, sends via Gmail API, returns success/error response.

  private async handleSendEmail(args: any) {
    try {
      const { to, subject, body, cc, bcc } = args;
  
      // Create email content
      const message = [
        'Content-Type: text/html; charset=utf-8',
        'MIME-Version: 1.0',
        `To: ${to}`,
        cc ? `Cc: ${cc}` : '',
        bcc ? `Bcc: ${bcc}` : '',
        `Subject: ${subject}`,
        '',
        body,
      ].filter(Boolean).join('\r\n');
  
      // Encode the email
      const encodedMessage = Buffer.from(message)
        .toString('base64')
        .replace(/\+/g, '-')
        .replace(/\//g, '_')
        .replace(/=+$/, '');
  
      // Send the email
      const response = await this.gmail.users.messages.send({
        userId: 'me',
        requestBody: {
          raw: encodedMessage,
        },
      });
  
      return {
        content: [
          {
            type: 'text',
            text: `Email sent successfully. Message ID: ${response.data.id}`,
          },
        ],
      };
    } catch (error: any) {
      return {
        content: [
          {
            type: 'text',
            text: `Error sending email: ${error.message}`,
          },
