dvcrn STM Assistant — Send on Behalf
Send professional emails from a dedicated agent inbox on behalf of your human.
Setup Requirements
- Agent inbox — via AgentMail (
mcporter call agentmail.create_inbox displayName="Your Assistant") or any SMTP provider - Hosted signature logo — small image (60x60px), hosted URL (Gmail blocks inline base64)
- mcporter with agentmail configured
Sending Protocol
Every outbound email MUST:
- CC your human — no exceptions. They see every email you send.
- Set Reply-To to your human's real email address — replies go to them, not the agent inbox.
- Use full legal name on formal correspondence.
- Include the branded signature:
<div>
<div style="font-weight: bold;">Human's Full Name</div>
<div>human@email.com</div>
<img src="https://your-hosted-logo.png" width="60" height="60" />
<div style="color: #aaa; font-size: 10px;">Sent on behalf of [Name] by their personal assistant</div>
</div>
Approval Rules
- Routine emails (scheduling, follow-ups, informational) — send directly, notify human after
- High-stakes emails (legal, financial, employment, first contact with important people) — draft and get explicit approval before sending
- When in doubt → ask first
Sending via AgentMail
mcporter call agentmail.send_message \
inboxId=your-agent@agentmail.to \
to='[{"email":"recipient@example.com","name":"Recipient Name"}]' \
subject="Subject Line" \
html="<p>Email body with signature</p>" \
cc='[{"email":"human@email.com"}]'
Important: Use text (plain text) or html (formatted) parameters. Never body or htmlBody — those don't exist and produce empty emails.
Inbox Monitoring
Check for replies on a regular cycle (heartbeat or cron):
mcporter call agentmail.list_threads inboxId=your-agent@agentmail.to limit=5 labels='["unread"]'
After processing a reply:
mcporter call agentmail.update_message \
inboxId=your-agent@agentmail.to \
messageId=MSG_ID \
removeLabels='["unread"]' \
addLabels='["processed"]'
Always mark processed emails. Unread inbox = broken assistant.
