An AI agent for a company Facebook Page: what it does and how we work with it

Running a company Facebook Page is repetitive work: text, a picture, a date and a check. An AI agent, a program you give tasks to in plain language, can take on part of it. We run our own Page this way. This article covers what such an agent can do, how we work with it and what to watch out for.

What an agent can do for a company

These are ideas for what can be built. We do not do all of this ourselves yet, and some of it needs extra permissions.

• A clinic or salon. The agent drafts posts about free slots and closures from the calendar.
• A shop. It turns a list of new products into draft posts with a photo and price.
• A club or association. It turns the calendar into event announcements and writes a short summary afterwards.
• A service business. It turns photos of finished work and a few sentences from an employee into a description ready to publish.
• Insights. Each week it sums up which posts worked and suggests the next ones.
• Comments and messages. It drafts replies and a person approves them. Meta also describes automatic replies to messages.
• Instagram. The API handles publishing and comments on Business and Creator accounts, so content can be adapted for both channels.
• Ads. The agent prepares a campaign, and a person launches it and sets the budget. Meta has an MCP server for this. We have not run it ourselves yet.

The same approach works beyond Facebook. Our agent also works with Google Play Console on releases, store listings and screenshots, and with Search Console on checking indexing. You can connect a CRM, a shop or an order system in a similar way if they have an API.

How it works for us

Our way of working is simple, and every post goes through a person:

1. The request. The owner writes, for example: "Prepare a post about the article on a first app and schedule it for Thursday at 9:00".
2. The draft. The agent reads the article and our writing rules, and checks the facts against the sources.
3. The preview. It shows the text and the post's picture. Nothing reaches Facebook yet.
4. The decision. The owner edits or approves. A changed text needs new approval.
5. The post. The agent publishes or schedules it. Facebook publishes a scheduled post itself.
6. The check. The agent reads the post back, compares the text and opens it without logging in.
7. The record. The date and text go into one file.

That is how the post about our new website came about. The first version was too technical, so we rewrote it for clients. The owner chose the picture from more than a dozen options.

What you need to set up

The agent does not sign in to your account and does not know your password. It gets separate access that you can withdraw at any time. That takes a few things:

• a business portfolio at Meta with your Facebook Page
• a technical app in Meta's dashboard, which is not a phone app and which nobody installs
• a separate account for the program, which Meta calls a system user
• an access key, called a token, stored somewhere safe
• an agent running on your computer, such as Claude Code or Codex

On top of that come permissions, a privacy policy and switching the app to Live mode. Meta may require App Review, though it did not for us, and not every business has system users. It is not hard, but it is easy to make a mistake you do not see straight away.

The traps we hit

• A post only we could see. The agent published its first post and the owner could see it on their own account. It looked fine. In a private window, though, Facebook said the content was not available. The cause was the app's Development mode, as data from this mode can only be seen by people with a role on the app. After switching to Live mode the post became visible. Since then we check every post without logging in.
• A cut-off token. Saving it through a Terminal prompt cut the key to 128 characters. Now we paste it into a system dialog, so it stays out of the chat. After saving we check only its length.
• What the API will not do. The API can only read the Page button. It also refused to change our username or pin a post. A person does those.
• The link limit. A Page may have a limit of 2 posts or comments with links a month, although Meta notes this does not apply to every Page. So we plan at most two posts with links a month.

The rules we set

The agent has access to the company's public profile, so we started with rules:

• A person approves every post. The text, the picture and the date.
• The agent does not talk to customers. A person handles messages, and a reply to a comment needs approval.
• The budget and payments stay with the owner.
• The access key never goes into a chat, a repository or a log. An agent that fetches a key on its own can also read it. That is why the key is separate and can be withdrawn at any time.
• Content follows the same rules as the website. Meta reduces the reach of posts that ask for reactions, so we do not ask for them.

What you can do on your own and what is worth outsourcing

For one post a week you do not need an agent. The planner in Meta Business Suite lets you set the date.

An agent starts to make sense when posts come from data you already have, such as a calendar, a shop or a list of projects. It also makes sense when Facebook needs to work with other systems. Then someone has to set up access, rules and checks, and keep an eye on them. That is worth outsourcing if nobody at your company wants to manage it.

Agree three things before you start. Who approves posts when the owner is on holiday. Where the agent gets its data and who keeps that data up to date. What happens when a post goes out with a mistake, meaning who fixes it and how quickly.

This describes the position on 4 November 2026. Meta often changes its dashboard and rules. If you have an idea where an agent like this would help, contact us. We will tell you whether it makes sense for your company.
