Agentmail
Give your product agent a real email inbox API—send, receive, and thread mail like Gmail—so workflows can sign up, verify accounts, and talk to humans over email.
Overview
ai.smithery/agentmail is an MCP server for the Build phase that connects coding agents to the AgentMail inbox API so AI agents can send and receive email.
What is this MCP server?
- AgentMail inbox API designed for AI agents (send/receive email semantics)
- Smithery-hosted streamable HTTP MCP entry (v1.0.0)
- Bearer smithery_api_key required for remote auth
- Open-source bridge: agentmail-to/agentmail-smithery-mcp on GitHub
- Positioned as “Gmail-like” dedicated inboxes for agents—not human-only SMTP snippets
- Published server version 1.0.0
- Repository github.com/agentmail-to/agentmail-smithery-mcp
- Smithery remote URL server.smithery.ai/agentmail
Community signal: 4 GitHub stars.
What problem does it solve?
Building agent email from scratch means wrestling with providers, webhooks, and threading when you just need an inbox that your agent can use like a user account.
Who is it for?
Indie builders creating agents that must receive magic links, answer customers, or run email-driven workflows in production-ish prototypes.
Skip if: Bulk marketing blasts, high-volume transactional mail at enterprise scale without AgentMail’s own limits, or teams that only need read-only Gmail OAuth in a browser.
What do I get? / Deliverables
Once configured, your agent stack can provision and operate agent inboxes through MCP tools backed by AgentMail instead of one-off SMTP scripts.
- MCP-accessible inbox operations for agent send/receive flows
- Faster integration of email-backed agent features in your codebase
- Documented remote endpoint for team MCP configs (server.smithery.ai/agentmail)

Journey fit
Agents that ship as products need comms infrastructure; this MCP lands while you wire agent capabilities and external integrations. agent-tooling is the right shelf because the value is inbox primitives for autonomous agents, not generic frontend UI.
How it compares
Agent inbox API over MCP, not a copywriting skill or a newsletter growth playbook.
