Question 1

Can Grok post to social media on its own?

Accepted Answer

No. Grok can read X, but it cannot publish to X, Instagram, LinkedIn or any other network. PosteAhora is the MCP server that gives it that ability: you connect your accounts in PosteAhora once, and Grok publishes through those connections. It never sees your passwords, only the tools we expose.

Question 2

How do I add PosteAhora to Grok?

Accepted Answer

In PosteAhora, open AI & Integrations → Grok and copy your connector URL. On grok.com, go to Connectors, click New Connector, choose Custom and paste the URL. Grok discovers the tools by itself and they show up in your chats.

Question 3

Which Grok plans can add a custom connector?

Accepted Answer

Custom connectors are a paid Grok feature, and xAI decides which plans get them. On Grok Business and Enterprise, a team admin provisions the connector first. If you don't see New Connector → Custom on grok.com, your plan doesn't include it yet. The xAI API route below works on any API account.

Question 4

Why a connector URL and not a sign-in?

Accepted Answer

The connector URL carries your access, so Grok needs nothing else and it works however Grok handles authentication. Treat it like a password: anyone with it can post as you. You can revoke it from AI & Integrations in PosteAhora at any time and create a new one.

Question 5

Does it work with the xAI API?

Accepted Answer

Yes. Pass PosteAhora as a remote MCP tool in the Responses API: type mcp, server_url https://mcp.posteahora.com/mcp, and a PosteAhora API key as the authorization. xAI connects to our server for you, over Streamable HTTP. The same call works with the OpenAI SDK pointed at api.x.ai.

Question 6

Does posting to X through Grok cost anything extra?

Accepted Answer

Not from Grok's side. On ours, every X post, whether you, Grok or the API created it, counts toward your plan's monthly X post allowance. Other networks don't have that allowance.

Question 7

Will Grok publish something I did not approve?

Accepted Answer

A scheduled post waits in your PosteAhora queue, where you can edit or delete it before it goes out. Nothing leaves early unless you ask Grok to publish it now. Ask Grok to save a draft or an idea instead if you want to review everything first.

Question 8

What about Grok Bot and Grok Build?

Accepted Answer

They connect to the same server. Grok Bot is xAI's always-on agent with its own cloud computer, good for recurring posting. Grok Build is xAI's coding agent in the terminal, good for announcing releases. Each has its own page with setup steps.
