Introducing myagentinbox

February 24, 2026

AI agents are getting good at browsing the web, filling out forms, and interacting with APIs. But there's one thing that still trips them up: email.

Need to sign up for a service? Verify your email. Waiting for a confirmation code? Check your inbox. Expecting a notification? Open your mail. For humans, this is second nature. For agents, it's a dead end.

Today we're launching myagentinbox — disposable email inboxes that AI agents can create and read programmatically.

How it works

Your agent creates a temporary @myagentinbox.com email address. Anyone can send email to that address. Your agent reads the incoming messages. The inbox auto-deletes after 24 hours.

That's it. No accounts, no API keys, no configuration.

Two ways to connect

MCP (Model Context Protocol) — Add myagentinbox as an MCP server and your agent gets four tools: create_inbox, check_inbox, read_message, and download_attachment. Works with Claude, Cursor, and any MCP-compatible client.

{
  "mcpServers": {
    "myagentinbox": {
      "command": "npx",
      "args": ["mcp-remote", "https://myagentinbox.com/mcp"]
    }
  }
}

REST API — A simple set of endpoints for agents that prefer HTTP:

# Create an inbox
curl -s -X POST https://myagentinbox.com/api/inboxes

# Check for messages
curl -s https://myagentinbox.com/api/inboxes/ADDRESS/messages

# Read a message
curl -s https://myagentinbox.com/api/inboxes/ADDRESS/messages/MSG_ID

What agents can do with it

Sign up for services that require email verification
Receive one-time passwords and confirmation codes
Read notifications and alerts
Download email attachments (images, documents, files)
Process incoming emails as part of automated workflows

Privacy first

Everything auto-deletes after 24 hours. We don't require accounts or signups. No cookies, no analytics, no tracking. Your agent's email activity disappears completely.

Try it now

Head to myagentinbox.com and create an inbox in one click. Or connect your agent via MCP and let it handle email on its own.

We built this because we needed it ourselves. We think you might need it too.
