Implementation Reference

• src/index.ts:190-222 (handler)

  The tool registration and handler implementation for 'send_email' in src/index.ts. It defines the input schema for email sending and uses an inbox object to dispatch the email.

  server.registerTool('send_email', {
    title: 'Send Email',
    description:
      'Send an email from an inbox. Requires a verified account (Tier 1+). ' +
      'To reply within a thread, provide in_reply_to with the Message-ID of the email being replied to.',
    inputSchema: {
      inbox_id: z.string().describe('Inbox ID to send from'),
      to: z.array(z.string()).describe('Recipient email addresses'),
      subject: z.string().describe('Email subject'),
      body_text: z.string().describe('Plain text email body'),
      body_html: z.string().optional().describe('HTML email body (optional)'),
      cc: z.array(z.string()).optional().describe('CC recipients'),
      in_reply_to: z.string().optional().describe('Message-ID of the email being replied to (enables threading)'),
    },
  }, async ({ inbox_id, to, subject, body_text, body_html, cc, in_reply_to }) => {
    const inbox = await getInbox(inbox_id);
    const result = await inbox.send({
      to,
      cc,
      subject,
      body: { text: body_text, html: body_html },
      inReplyTo: in_reply_to,
    });
  
    return {
      content: [
        {
          type: 'text' as const,
          text: `Email queued for delivery.\n\nEmail ID: ${result.id}\nStatus: ${result.status}`,
        },
      ],
    };
  });
