SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

AgentMail lets an AI agent operate with its own dedicated email identity so it can send, receive, and manage email conversations without relying on the user’s personal inbox.

Core Features & Use Cases

  • Dedicated agent inbox: Create and manage agent-owned inbox addresses (e.g., hermes-agent@agentmail.to) for authentic email-based workflows.
  • Autonomous email operations: Send new messages, reply within threads, and forward messages as part of ongoing tasks.
  • Inbox conversation management: List inboxes and threads, retrieve specific threads, and download attachments when needed.
  • Integration via MCP: Provides tool access through the AgentMail MCP server, enabling the Hermes agent to call email functions on demand.

Quick Start

Configure an AgentMail MCP server in your Hermes config, then ask the agent to create a new inbox and report the assigned email address.
