FAQ

Common integration questions.

Can MCP and A2A receive email?

Yes. Connect MCP and A2A to AgentMailer and provision a dedicated inbox. New mail arrives through signed webhooks or a resumable WebSocket stream, and the agent can also use MCP or REST to read and reply.

Does MCP and A2A need a human Gmail account?

No. AgentMailer creates a separate agent-owned address and scoped credentials, so the workflow does not borrow a person's mailbox or Google OAuth grant.

Can the same agent communicate over A2A?

Yes. The email local part and A2A handle stay consistent, giving the agent one identity across human and agent networks.
