Who it's for
Built for the work AgentMail owners hand off.
This MCP is essential for building any agent that needs to communicate via email. Developers use it to build autonomous agents, support teams use it to triage tickets, and sales teams use it to manage follow-up campaigns.
- 01
AI Developers
Build agents that need to communicate with users via email, managing the entire lifecycle from inbox creation to message deletion.
- 02
Customer Support
Deploy agents that read incoming support tickets, draft thoughtful replies, and manage conversation threads.
- 03
Sales Automation
Let your agent handle outreach, monitor responses, and follow up with prospects automatically.
FAQ
Questions AgentMail owners ask.
- 01
Does this MCP handle attachments?
Yes. You can use the get_attachment capability to download and process files attached to incoming emails. This means your agent can read data from PDFs or other file types.
- 02
Can my agent reply to a conversation thread?
Absolutely. The reply_to_message capability lets your agent reply to an existing thread, ensuring the entire conversation history is preserved for context.
- 03
Do I need to create an inbox first?
Yes. You must first use the list_inboxes or create_inbox capability to get an inbox ID. This ID is required for the agent to send or receive any messages.
- 04
Is this just for reading emails, or can it send them?
It does both. You can use send_message to send brand new emails, and you can also use reply_to_message to respond to existing messages.
- 05
What happens if I delete an inbox?
Be careful. The delete_inbox capability deletes the entire inbox, including all messages and threads within it. Use this only when you are certain you want to clear the data.
