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.

Everything an inbox does.
Through one connection.
Pick a part to watch it work. Each one is a real tool, command or event.
$ openemail temp newOne address to paste.
Any MCP client.
The server speaks MCP over HTTP. Add its address to your client, sign in once in the browser and approve what it may reach.
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.
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.

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.

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

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.
Agent callsClick around the mailbox to see each call.

- ›getThread{"id":"thr_7c1e4a90"}{"subject":"Refund for order 4821","messages":1}
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.
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.
