Email for AI agents

# An inbox for your agent. On terms you set.

Connect Claude Code, Codex, Cursor or any MCP client to a real mailbox. It reads, replies and sends from your addresses, within the access you approve, for as long as you allow.

Or let the agent set itself up

Paste this into any agent that can run a terminal command. It reads a guide written for agents, then tells you the one step that needs you.

Prompt for your agent

Run \`npx @openemail/cli agents\` and read the guide it prints. Then tell me what I need to do to sign you in to my Nextmail mailbox, and wait for my go-ahead before you send anything.

## Built to be handed over. Then left alone.

MCP tools

Each named for what it does. An app sees only the tools its approval covers.

No key to paste

Browser sign-in

The client signs in through your browser, and you approve it like any other app.

Accounts needed

openemail temp new makes a disposable inbox that takes mail for up to a day.

548

API operations

The same mailbox from a script, through the SDK, the command line or plain HTTP.

## Your agent's mailbox. Every click is a tool call.

Use it the way your agent will. Each action shows the MCP call that does the same thing.

## You approve it. Like any other app.

When the client signs in, you pick the workspace, what it may do, which addresses it reaches and for how long. Account → Connected apps changes or removes it later.

- **Your role is the ceiling**
  An app never holds a permission you lack, and when your role loses one, the app loses it on its next call.
- **Some things are never granted**
  No app can create or rotate API keys, open billing or manage the workspace, whatever you tick.
- **Risky changes wait for you**
  Adding a webhook, writing a rule, changing roles or removing a domain needs your verification code, or a 60-minute allowance you switch on for that app.

[How an approval is scoped](https://openemail.uk/docs/mcp/scope.md)

## Asked first. Answered plainly.

## 501 tools. Each named for what it does.

An app gets only the tools its approval covers, so one held to reading has no sending tool at all.

[What each tool does](https://openemail.uk/docs/mcp/tools.md)

Who it is for

## One mailbox. Four ways in.

### Business

Addresses for everyone, members never counted as seats.

### Developers

The same mailbox over an API, an SDK, a CLI and MCP.

### AI & agents

An inbox your agent can work, with access you approve.

### Personal

A free address at openemail.uk, with the client behind it.

## Give it an address. Watch it work.

MCP, the API and the command line come with every plan, the free one included. Connect a client and approve exactly what it reaches.
