How to Schedule a Meta Post (Facebook, Instagram, Threads) with Socialic MCP

To schedule a Meta post with Socialic MCP, you ask Claude to post to Facebook, Instagram, and Threads in one request — it lists your connected channels, checks each platform’s media rules (Instagram needs at least one image or video, Threads accepts images only, Facebook is the most flexible of the three), asks for anything missing, and schedules all three together or on their own times.

Facebook, Instagram, and Threads get grouped together here because they usually are in practice — all three trace back to the same Facebook-based connection in Socialic, and people tend to post to them as a set. But “Meta” isn’t one platform with one rulebook. This guide covers what’s shared, what’s different, and how to hand Claude a single request that respects all three.

In Socialic, an Instagram Business or Creator account and a Threads account both connect through a Facebook Page — see how to connect your social accounts to a scheduler for that setup. Once connected, each still shows up to Socialic MCP as its own separate channel with its own id, its own caption limit, and its own media rules. Grouping them in one request is a convenience, not a technical requirement — you could just as easily schedule each one separately.

Before asking Claude to post, it helps to know which platform is strict about what. Socialic MCP enforces the same rules the dashboard does:

This is also why “post this everywhere” doesn’t always mean the same request underneath. A video that works for Facebook and Instagram will get rejected the moment Threads is in the channel list — Claude catches this before submitting anything, not after.

Start by asking Claude something like “list my Facebook, Instagram, and Threads channels” — or just whichever of the three you’ve actually connected. This calls socialic_list_channels, which returns each channel’s id, status, caption limit, and requirements — so Claude (and you) know exactly what each one needs before drafting anything.

The same request works the same way in Claude Code:

If you already know the exact filename you want, you can name it directly in the same request that schedules the post — see the example below. If you don’t remember it, ask first: “what images do I already have in my Socialic media library?” This calls socialic_list_media_files and lists everything you’ve uploaded, so you can just tell Claude which one to use.

That “media library” is the same File Manager you’d see in the Socialic dashboard — drag-and-drop uploads, storage totals, the works. If you’ve never used it, here’s a quick rundown of uploading and organizing media; anything in there is fair game for Claude to reference by name, no re-upload needed.

A typical exchange looks like this:

Because the media was a single image, all three rules were satisfied automatically — Instagram had its required media, Threads got an image instead of video, and Facebook accepted it without needing anything at all. Swap that image for a video and the exchange changes: Claude would flag that Threads can’t take it and ask whether to drop the video or drop Threads from this post.

Here’s a real one, scheduling to a single connected Facebook Page with an existing media library file instead of a fresh upload:

Two things worth noticing in that exchange:

The Claude Code version of the same request, continuing straight from the media library lookup above:

That follow-up — “post the same photo to Threads too” — is the same idea as scheduling to all three at once, just spread across two messages instead of one. Claude already has the image and the caption from context, so it only needs the new channel to act on. This is also how you’d handle the case from earlier in this guide, where a video works for Facebook and Instagram but not Threads: schedule the two that take video together, then send Threads its own message with a still image instead.

One caption for three platforms works, but tailoring it usually performs better — Facebook tolerates a longer caption, Instagram rewards hashtags, Threads favors something short and conversational. You can ask for this directly:

Under the hood this is socialic_schedule_post taking your base caption as a shared default, with a per-channel override for Instagram and Threads — the same mechanism that lets you set a different scheduled time per platform, if you’d rather stagger Facebook, Instagram, and Threads across the day instead of posting all three at once.

“Meta” is a convenient shorthand, not a single set of rules. Facebook is the forgiving one, Instagram is the strictest about media, and Threads is the odd one out with images-only. Socialic MCP already knows all three rulebooks — the only thing you need to bring is media that satisfies whichever platforms you’re posting to.
