Give an agent its own inbox: send, receive, and pull signup codes from real 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
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.
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: create_inbox, list_inboxes, delete_inbox, send_email,
read_messages, read_message, reply_to_message, forward_message,
wait_for_email, get_verification_code, get_verification_link,
list_threads, read_thread, get_usage.
The one agents reach for most is get_verification_code — 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.
