Grok can’t see your accounts today. Add HeyMetra and it can.
A Grok connector lets Grok read your accounts as it answers. HeyMetra is one, for your marketing and revenue accounts.

Over our last six email campaigns, how did the list grow and how many people unsubscribed each time?
Read Zoho Marketing Automation with HeyMetra
The list grew from 8,400 to 9,150. In the two September weeks you sent twice a week, unsubscribes doubled; once a week looks like the pace your list takes.
Not in the grid because nothing is read from them: Slack, Telegram and Email are destinations. Each one lets Grok send to the place you linked. A message goes out as soon as it is sent. Switch on Ask before sending to approve each one first; an email to an address you did not save always waits for you.
Why one server rather than four
Grok treats each connector you add as a separate source. That works for how many orders came in this week. It does not work for which of those orders started as a chat on your site, because the answer sits in more than one account and Grok would be joining them by guesswork. Behind one connection, every account answers in the same conversation from one sign-in, so Grok is not juggling a server per account.
Held against the two alternatives worth naming: HeyMetra vs AdKit, an MCP server for ad accounts alone, and HeyMetra vs Supermetrics, which lands a copy of the data somewhere rather than answering out of the account.

Adding one in Grok
See the setup
Why Grok: The assistant people already have open in X. Like Claude and Perplexity, the connection is added once to the account rather than to a file.
Worth knowing for Grok: xAI calls this “bring your own MCP”.

Authorize the accounts you want reachable. This happens once, in HeyMetra, and is the part that is the same wherever you ask. No HeyMetra account yet? The trial covers this step.
In Grok, open grok.com/connectors → New Connector → Custom, and paste the address.

Ask Grok something that needs one of the accounts. The model picks the tool; you never name it.
These interfaces move, and this one has moved before. Where a step here disagrees with what is on your screen, trust the screen. Then check Grok's own documentation, which is what these steps were written from. And tell us, so the page stops being wrong for the next person.
Use it from the Grok subscription you already pay for.
Pricing
There is no second model to buy here. The answering happens in Grok; HeyMetra supplies the accounts and asks you before anything in them changes.
grok.com/connectors → New Connector → Custom. It is added to your account rather than to a file, so it is there in every conversation afterwards and on every device you sign in on.
Is there anything specific to Grok I should know?
xAI calls this “bring your own MCP”. Everything else is the same as it is anywhere else: one address, the sign-in you already have, and the tools appear.
Does Grok support MCP?
Yes. Grok adds remote MCP servers from grok.com/connectors: New Connector → Custom, which asks for the MCP server URL. xAI calls this "bring your own MCP".
Where do I add an MCP server in Grok?
Grok adds remote MCP servers from grok.com/connectors: New Connector → Custom, which asks for the MCP server URL. xAI calls this "bring your own MCP". After that, Grok discovers the tools the server exposes and decides which to call while it answers you. You never name a tool.
Is a remote connector different from a local one?
Yes. A local one runs as a process on your own machine and stops when you close Grok. A remote one runs on the operator’s infrastructure and is reached over HTTP, so there is nothing to install and nothing to keep running, and the credentials live with the operator.
Can a connector change my accounts?
Only if you said it may. Connecting an account to HeyMetra asks that question once: read-only, or may the assistant propose changes there too. An account left read-only carries no tool that can change anything, and Search Console and Jira connect read-only with no option to change. Where you said yes, Grok tells you in one line what it will change and waits; nothing reaches the account until you say yes in the chat. A message to a channel you linked goes out when it is sent, unless you switch on Ask before sending.
Other AI assistants
The same connection, from any of them. What differs is where the setting lives and what that app calls it: Grok says “connectors”.
An MCP connector is one authorized account behind an MCP server. How a standard connector differs from a custom one, and when you need the second.
