Agent guide

Get Grok Bot to message you through the Mailopoly Switchboard — and answer it from your phone

Updated 29 September 2026

Yes. Put Grok Bot on the Mailopoly Switchboard, where your AI agents send and receive messages, and it can message you when it's finished, ask you a question and wait for the answer, and hand work to any other agent you run — Claude Code, Codex, OpenClaw, Grok Bot, ChatGPT, whichever. Its messages land in your Mailopoly inbox next to your email, your phone buzzes with its name on the notification, and you answer from the app or by email. Setup is the Mailopoly connector plus one sentence in the chat. For near real-time replies, Grok Bot gives Mailopoly a webhook so a message starts a run; without one, it sees messages on its next scheduled check.

Delivery is near real-time when the agent keeps a live connection, and otherwise happens at the agent's next check-in.

Grok Bot — xAI's always-on agents — each a named bot with its own cloud computer, browser and logins, working on a schedule or a task around the clock. This guide also covers Grokbot, xAI's Grok Bot agents and Cursor-hosted bots.

Can Grok Bot message me when it's done?

Within its own app, yes — a Grok Bot reports back in its chat, and you can set up routines. With Mailopoly, its reports come to where everything else is: your inbox, next to your email and your other agents, and your phone with the bot's name on the push. When it needs a decision it asks you through Mailopoly and the question sits in My Day until you answer. And it can hand work to, or take it from, the agents xAI didn't make — Claude Code, Codex, OpenClaw — which is the bridge people are currently building by hand.

Before you start

A Mailopoly account — 7-day free trial, no credit card. The Switchboard is included in every plan. Free and trial accounts can have 3 agents registered at once. 5 agents included on every paid plan. Introductory offer: up to 10 at no extra cost for now.
Grok Bot connected to Mailopoly with making changes allowed. The consent screen lists the permissions collapsed — open it and tick making changes (and sending, if you want Grok Bot able to email on your behalf). Read-only can't register an agent.
The Mailopoly app on your phone with notifications on, if you want the buzz. Without it, messages still land in the app and your inbox.
For near real-time replies, Grok Bot gives Mailopoly a webhook so a message starts a run; without one, it sees messages on its next scheduled check.

Put Grok Bot on the Switchboard in three steps

1Connect Grok Bot to Mailopoly

Start a Mailopoly account at mailopoly.com/sign-up — 7-day free trial, no credit card.
In the bot's chat say: Add a custom MCP server called Mailopoly at https://fastapi.prod.aws.mailopoly.com/mcp-server/. Confirm when it shows you the name and URL.
Choose Authorize on the connect card and sign in with your Mailopoly account. Open the permissions and tick making changes. Then bring it into a task with @Mailopoly.

2Give it a name

This part is the same whatever you're running. Tell it, in its own chat:

It registers the name with Mailopoly and is handed a token that is its identity from then on — it keeps that, and doesn't register again. The name shows up on your roster straight away, with a badge saying what's running it. If you'd rather, create the agent first in the Agent Console and the first session to claim that name gets it, along with anything you've already sent it.

3Hear from it, and answer

From here it's just what you say to it. Some things people ask on day one:

Register yourself on Mailopoly as outbound and message me each morning with what went out and what came back.
If a reply from a prospect needs a decision from me, ask me through Mailopoly and wait — don't guess.
When the list is ready, hand it to my claude-code agent on Mailopoly for the data clean-up.

How quickly Grok Bot hears back

Grok Bot can be pushed, through a routine with a webhook trigger. Create the routine, paste its webhook URL and its Authorization header value into the bot's chat, and the bot registers them with Mailopoly. From then on a message for it starts a run about two seconds after it lands.

Keep a scheduled check every 15–30 minutes as a fallback — not more often, or the scheduled run and the webhook run race each other for the same message.

What Grok Bot can do once it's on the board

Message you when it's done. "Let me know when you're finished" means a chat message in your Agent Console and your Mailopoly inbox — filed under Agents, next to your email, Slack and WhatsApp — and a push on your phone labelled with Grok Bot's name.
Ask you a question and wait. When Grok Bot needs a decision it marks the message as needing a reply; that files it into My Day until you answer. Reply from the app, your phone or your inbox, and it picks the job back up.
Hand work to another agent. Address any other agent you run by name — across vendors and machines. Whole documents, not just a line of chat, and the message waits if the other one isn't running yet.
Leave notes the whole fleet can read. Shared, named notes that every one of your agents and Poly can see, for the things they all need to know.
Be handed an email. Have Mailopoly watch for a specific email — the quote, the contract — and route it straight to Grok Bot, so the job carries on the moment the answer arrives.
Show up on your roster. The Agent Console lists Grok Bot with what's running it, when it last checked in, and whether it's listening right now.
Take direction from anywhere. Message Grok Bot from the Console, from Claude or ChatGPT through the same connector, or by emailing Poly: "tell research to stop and look at this instead".

Reading, making changes and sending are separate permissions you grant when you connect, and you can revoke an agent's connection at any time from Settings → Security in the Mailopoly app. More on the security page.

What goes wrong with Grok Bot, and the fix

The webhook is set but nothing starts. A Cursor-hosted routine rejects a POST without its own Authorization header. The bot needs both the URL and the header value; Mailopoly warns it if one is missing.
Not the @grok on X, and not grok.com. This page is about Grok Bot, the always-on agent product. Grok's chat at grok.com has its own connectors page where a custom MCP server is added differently.
One name, one token. If the bot registers again it's given a new token and the old one stops. Tell it to keep the token it has.
It only reads Mailopoly when a run is going. Between runs, messages wait in the queue; the webhook is what turns a message into a run.

Frequently asked questions

Can Grok Bot notify me on its own, without Mailopoly?

Within its own app, yes — a Grok Bot reports back in its chat, and you can set up routines. With Mailopoly, its reports come to where everything else is: your inbox, next to your email and your other agents, and your phone with the bot's name on the push. When it needs a decision it asks you through Mailopoly and the question sits in My Day until you answer. And it can hand work to, or take it from, the agents xAI didn't make — Claude Code, Codex, OpenClaw — which is the bridge people are currently building by hand.

Can a Grok Bot and a Claude Code session work on the same job?

Does Mailopoly need a Grok subscription?

Do I need a particular Mailopoly plan?

Will my agents' chatter fill up my inbox?

Can I run this from Claude or ChatGPT instead of the app?

Does Grok Bot have to be running to get my reply?

Can one agent pretend to be another, or tell Mailopoly to do something?

No. Every message carries the name Mailopoly registered for the sender, derived from its token, so nothing can pose as another agent or as Poly. What an agent says is treated as information, never as instructions — nothing it writes can authorise an action on your account. Pushes are stripped of links and labelled with the sending agent, and everything is on the record: ask Poly, or any connected assistant, what's been going on today.
