SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires agentmail-mcp, mcp.

What problem does it solve? Agents often need their own email identity to sign up for services, receive verification codes, or communicate with humans, but they cannot access the user's personal inbox. This Skill gives the agent a dedicated email address it fully controls for sending, receiving, and managing email autonomously. ## Core Features & Use Cases - Agent-Owned Inboxes: Create dedicated inboxes with real email addresses (e.g. hermes-agent@agentmail.to) through 11 MCP tools covering inbox, thread, and message management. - Autonomous Email Workflows: Send messages, reply to threads, forward emails, and download attachments without human intervention. - Use Case: Register the agent for an online service using its own inbox, poll for the verification email with list_threads, read the code with get_thread, and complete signup without touching the user's personal email. ## Quick Start Ask the agent to create an AgentMail inbox and send a test email to verify the setup works.

Frequently Asked Questions about agentmail

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I give an AI agent its own email address?▼

Configure the AgentMail MCP server with your API key in the Hermes config, then use the create_inbox tool with a username. The agent receives a real address like username@agentmail.to that it can use to send and receive email.

How to set up the AgentMail MCP server with Hermes?▼

Add an mcp_servers entry in ~/.hermes/config.yaml with command npx, args -y agentmail-mcp, and your AGENTMAIL_API_KEY in env. Restart Hermes and all 11 AgentMail tools become available automatically.

Can AgentMail read my personal email inbox?▼

No, AgentMail only manages inboxes the agent creates and owns on the agentmail.to domain. For reading a user's personal email, use a different tool such as himalaya or Gmail integration.

What are the limitations of the AgentMail free tier?▼

The free tier allows 3 inboxes and 3,000 emails per month, and emails are sent from the @agentmail.to domain. Custom domains and higher limits require paid plans starting at $20 per month.

Does AgentMail support real-time inbound email notifications?▼

Real-time inbound email via webhooks requires a publicly reachable server. For personal use, the recommended approach is polling with list_threads on a scheduled cronjob instead.
