Atomic Mail Agentic

Read and write email through the Atomic Mail from an AI agent. Handles proof-of-work authentication and JMAP so the agent thinks in JMAP method calls. Use when the user asks to register an email inbox, list mailboxes, fetch or send email.

Atomic Mail Agentic is an email provider for autonomous AI agents, built by Atomic Mail. Agents register their own @atomicmail.ai inbox and manage it end to end — no human setup, verification, or ongoing intervention.

The service is built on JMAP (RFC 8620), so agents get a full mailbox API: read and send mail, create drafts, manage threads, search, and more. JMAP is well represented in LLM training data, so models already speak it fluently — they rarely hallucinate request shapes, which means fewer retries and more reliable automation.

Access is gated by a novel proof-of-work (PoW) signup protocol: strong anti-abuse properties without CAPTCHAs or manual approval, so agents can onboard and operate completely hands-free.

Atomic Mail provides a number of standard integration paths — MCP, AgentSkill, REST API, and more — which makes it highly available on any agent: Claude Code, Codex, GitHub Copilot, Cursor, Hermes, OpenClaw, Pi, Kilo Code, and others. Whatever your workflow is, you can automate inbox management easily.

This repository ships the client integrations: MCP, shell CLI, ClawHub, Dify plugin and more, exposing those APIs through three tools: register, jmap_request, and help. All the connectors in this repo are pretty thin and are mainly needed to abstract away the complexities of the PoW protocol.

🚀 Quick Install

💬 Ready Prompt (any agent)

Read the instruction at https://atomicmail.ai (use default web_fetch tool or curl, if the former is not available) and create an inbox at Atomic Mail. Before creating ask for my preferred username. Make sure to complete all required post-install actions from the Atomic Mail instruction. Persist the instruction and make sure to refer it each time you interact with your inboxes. Usually standalone agents (e.g. Claude, Cursor, Kilo Code and others) are better suited for MCP use, while CLI-based agents (e.g. Claude Code, Open Code, Hermes, OpenClaw, Codex, Pi, etc) are better suited for AgentSkill use, but prefer your system/user guidelines.

🔌 MCP (stdio)

Add this to your MCP host config (or just ask your agent to do that):

{
  "mcpServers": {
    "atomicmail": {
      "command": "npx",
      "args": ["-y", "@atomicmail/mcp-github"]
    }
  }
}

Then restart the host and ask your agent to create an inbox.

🤖 What Your Agent Can Do

Atomic Mail is designed to run through an agent — not through manual inbox setup. You describe a workflow in plain language; the agent registers an @atomicmail.ai address, sends and receives mail, and keeps the thread going. You do not configure scripts, copy API keys between tabs, or memorize JMAP. Everything is automagical.

If the agent gets stuck, the integration is built to recover on its own: help ships embedded docs (presets, cron, troubleshooting), bundled JSON presets cover common operations, and errors include hints on what to try next.

Example workflows

Newsletter digest — "Subscribe your inbox to these newsletters, read everything, and email me a daily digest of what matters for AI tooling." The agent owns a dedicated inbox, filters noise, and surfaces only what matches your interests — without touching your personal mailbox.

Support inbox — "Monitor support@ and reply to tickets from our docs; escalate to me only when you cannot answer." The agent reads inbound mail, queries what it knows, sends complete replies, and hands off edge cases.

User research interviews — "Run an email survey: send these questions, follow up based on replies, and summarize findings." The agent conducts async interviews — respondents reply on their own schedule, no calls to book.

✨ Why Atomic Mail

Agents finish without asking their users for anything: PoW signup gives a real @atomicmail.ai inbox in ~30 seconds — no domain to verify, no credit card, no CAPTCHA walkthrough, no mail-server ops
Messages that actually arrive: continuously warming IP pool with relay overflow — deliverability matters when a human on the other side must read your mail
JMAP — an API agents already know: standard RFC 8620/8621, in LLM training data; batched method calls (query, fetch, draft, send) in one round trip — no vendor SDK to learn
Get unstuck inside the integration: errors ship plain-language hints; success responses suggest _next steps; help returns cheatsheets and worked examples — no web search required
No vendor lock-in: JMAP is an IETF standard; the inbox is portable to any compliant provider later
Presets when raw JMAP is overkill: bundled send_mail, list_inbox, reply, and more — pass a filename to jmap_request instead of generating method-call JSON from scratch
Same core everywhere: one auth, JMAP, preset, and help stack powers MCP and AgentSkill; separate credential dirs per inbox when you run many agents
