ai.smithery/agentmail is an MCP server that connects coding agents to the AgentMail inbox API so AI agents can send and receive email.
About
ai.smithery/agentmail is a Smithery MCP remote for AgentMail, an email inbox API built for AI agents rather than humans clicking in a webmail UI. developers shipping agent-first products—onboarding bots, support copilots, outbound research agents, or workflow automations that must receive verification links and reply in threads—register this during build/agent-tooling to expose inbox operations inside Claude Code, Cursor, or Codex. Instead of bolting together raw SMTP, DNS, and provider dashboards, you get an agent-oriented contract surfaced as MCP tools over streamable HTTP with Smithery authentication. You still own product policy: rate limits, abuse prevention, and PII handling are on your app. The server is a thin integration layer (agentmail-smithery-mcp) over the AgentMail service; pair it with your orchestration code and review before exposing inboxes to end users. It accelerates “agent has an email address” demos into something you can harden for launch.
- 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

What it does
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.
Who is it for?
Best when you're 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 you get
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)
