Dead Simple Email MCP server

Dead Simple Email

<!-- mcp-name: email.deadsimple/dead-simple-email -->

Email infrastructure for AI agents. One call gives an agent a real, deliverable inbox — no SMTP credentials, no DNS, no dashboard.

deadsimple.email · Docs · API reference

Sign up with no human in the loop

An agent can provision its own account, API key and live inbox in a single unauthenticated call:

curl -X POST https://api.deadsimple.email/v1/auth/agent-signup

That returns a trial account (1 inbox, 10 sends/hour, 25/day). Claim it later with a verified email to move to the Free plan, keeping the same key and inboxes.

MCP server

Listed in the official MCP Registry as email.deadsimple/dead-simple-email, and on Smithery and Glama.

Remote (recommended) — nothing to install:

{
  "mcpServers": {
    "dead-simple-email": {
      "type": "http",
      "url": "https://api.deadsimple.email/mcp",
      "headers": { "Authorization": "Bearer dse_your_api_key" }
    }
  }
}

Local (stdio):

{
  "mcpServers": {
    "deadsimple": {
      "command": "python",
      "args": ["-m", "deadsimple.mcp"],
      "env": { "DSE_API_KEY": "dse_your_api_key" }
    }
  }
}

14 tools: createinbox, listinboxes, deleteinbox, sendemail, readmessages, readmessage, replytomessage, forwardmessage, waitforemail, getverificationcode, getverificationlink, listthreads, readthread, getusage.

The one agents reach for most is getverificationcode — it pulls the OTP or magic link out of the newest inbound message, so an agent can sign itself up for a third-party service or clear a 2FA prompt without ever parsing an email body.

SDKs

pip install deadsimple-email
npm install @deadsimple/email

from deadsimple import DeadSimple

dse = DeadSimple("dse_your_api_key")
inbox = dse.inboxes.create(display_name="Support Bot")
dse.messages.send(inbox.inbox_id, to=["someone@example.com"],
                  subject="Hello", text_body="Sent by an agent.")

Framework integrations for LangChain, CrewAI, LlamaIndex, AutoGen and OpenAI Agents live in python/src/deadsimple/integrations/.
