Hermoso is a marketing MCP server: 906+ tools over one OAuth’d endpoint that let an agent research the ads already running in a market, generate finished image and video ads, publish them, and build the paid campaigns behind them. Grok Bot reaches all of it through one connection. This page covers one slice of that: what Grok Bot can actually do on Instagram, and what Instagram will not let it do.
Connect Hermoso to Grok Bot
- Fastest: add the Hermoso Marketing Bot template. Open the template and add it to Grok Bot. It arrives wired to Hermoso but with no key, because templates never carry secrets, so it asks for one: create a key under MCP & CLI → Terminal & API keys and paste it into the Bot’s chat. A key carries real spend authority, so treat it like a password.
- Or sign in from the Bot’s own terminal. Every Bot gets a browser, a filesystem and a shell, so the keyless install works there too:
Thenpm install -g hermoso && hermoso auth loginhermosocommand is then available to the Bot with nothing pasted into a config file. Settings → Plugins is a catalog of pre-built connectors that does not list Hermoso, so the template and the terminal are the ways in today. - Using Grok Build instead? xAI’s terminal coding agent is a separate product with its own setup: see Hermoso in Grok Build.
- Ask a Bot for something. “Pull my three closest competitors’ longest-running ads and remix the best hook into a 9:16 video,” or “post this render to the channel.” The agent picks the tools; you approve the spend.
Hermoso is not affiliated with or endorsed by xAI and does not claim to be. The Hermoso Marketing Bot template is published by Hermoso; the same steps are in the app under MCP & CLI, on the Grok Bot tab of the agent setup.
Then connect Instagram itself, once, under Settings → Connectors in Hermoso. That is an OAuth consent screen, so it is the one step that needs a browser. Everything after it is a tool call.
The Instagram tools Grok Bot gets
post_to_meta: publishes to Instagram withtarget: "instagram". Instagram is a visual channel and the API agrees: a post needs an image or a video.schedule_post: queues it on the shared calendar, with a per-channel caption if the copy should differ from your Facebook or LinkedIn version.list_meta_comments / reply_to_meta_comment / moderate_meta_comment: read, reply and moderate under a post.meta_page_insights / meta_post_insights: reach, impressions, saves and engagement, per account and per post.search_instagram: keyword search across public Instagram Reels, for research rather than publishing.
Two Instagram facts worth knowing before you automate anything. There is no native Instagram scheduling in Meta’s API, so a schedule is Hermoso’s queue rather than Instagram’s, and passing Facebook’s scheduleAt for Instagram is refused rather than silently posted now. And an Instagram caption cannot be edited once the post is live: the only thing Meta lets you change on a published post is whether comments are enabled. Deleting one is supported: manage_meta_post removes ordinary posts, Stories, Reels and entire carousel albums, though never a single card out of an album.
Instagram limits worth knowing before you automate anything
| Text | An Instagram caption is capped at 2,200 characters. It is enforced when the post is created or queued, so an overlong post is refused while you are still there to fix it instead of being silently cut on the way out. |
|---|---|
| Visibility | Public only. Meta’s Content Publishing API publishes immediately or not at all, and Instagram “has no unlisted, private or draft post.” If you want a review step on Instagram, it has to happen before the call, not after. |
| Carousel | 2 to 10 slides, and images and video may be mixed. That upper bound is Meta’s own, quoted in the capability table it enforces: “Carousels are limited to 10 images, videos, or a mix of the two.” The floor of 2 is ours, because one slide is not a carousel on any platform. A single-slide ask publishes as an ordinary post rather than being refused. |
| Which account | pageId. Instagram publishes through the connected Facebook Page, so the same identity field selects it. |
Try it in Grok Bot
Ask for it in ordinary language. These are plain sentences, not a DSL:
“Build me a 5-slide carousel from this week's product shots and a 9:16 video of the best angle, then stop and show me both before anything goes out.”
That walks search_instagram → plan_ad → render_ad → post_to_meta (target: "instagram"). Approval is Grok Bot’s setting rather than ours, and the shared machine is the reason to think about it: isolation is per user, not per Bot, so anything one Bot connects, every Bot on that machine can reach.
Grok Bot on Instagram: the part that bites
Instagram is the one channel where the CAPTION is final: Meta lets you change nothing on a live post except whether comments are enabled. Taking it down is fine, since manage_meta_post deletes posts, Stories, Reels and whole albums, so the thing worth a second look is the words. Everything upstream is reversible anyway: research, planning, rendering, captioning. Write the job so a person reads the caption before it posts.
For a long unattended run the hermoso CLI is the cheaper path: the agent shells out per command instead of carrying an 906+ tool manifest through every turn of a job that might run for days.
Research Instagram before you post
search_meta_ads covers Instagram placements as well as Facebook, since it is one library. For organic, search_instagram searches public Reels by keyword, which is the surface where the format actually moves; profile and hashtag pulls go through fetch_social_data and search_instagram_hashtag.
The paid half
Instagram placements are bought through the same Meta campaign tree as Facebook: create_meta_campaign → create_meta_adset → create_meta_ad, with placements selectable per platform and position. preview_meta_ad shows the real rendered ad per placement before you spend, and meta_insights breaks results down by age, gender, placement and country. That breakdown is what shapes the next creative.
What Grok Bot cannot do on its own
An agent with a budget is only useful if the blast radius is bounded, so the fence is in the server rather than in a prompt. Every ad campaign, ad set, ad group and ad is created paused, and the status switches that arm real money refuse to run without an explicit confirmation flag. Every render is quoted first (hermoso_capabilities publishes each model’s exact credit cost before anything spends). Credits are reserved before the first provider call and settled at the exact cost afterwards, so a failed dispatch refunds rather than leaving you billed for nothing. Deletes are confirm-gated too, and every campaign tree is read back from the ad platform before your agent tells you what it built.
One step is deliberately not headless: linking an account is an OAuth consent screen, so you connect the channel once in a browser. Everything after that is a tool call.

Frequently asked questions
Can Grok Bot post to Instagram?
Yes, through Hermoso's MCP server. Add the Hermoso Marketing Bot template from x.ai/bot/THQqogUKuhn1whWU0hrmb, which arrives wired to Hermoso and asks for an API key you create under MCP & CLI, Terminal & API keys. Or run npm install -g hermoso && hermoso auth login in the Bot's own terminal, which stores the credential with nothing pasted. Grok Bot then has 906+ tools, including the ones that publish to Instagram, plus the ones that research the ads already running in your market and render the creative in the first place.
How do I connect Instagram to Grok Bot?
Two steps, once each. Add the Hermoso Marketing Bot template from x.ai/bot/THQqogUKuhn1whWU0hrmb, which arrives wired to Hermoso and asks for an API key you create under MCP & CLI, Terminal & API keys. Or run npm install -g hermoso && hermoso auth login in the Bot's own terminal, which stores the credential with nothing pasted. Then connect Instagram inside Hermoso under Settings → Connectors, which is an OAuth consent screen in a browser. After that Grok Bot publishes to Instagram as an ordinary tool call.
What is the Instagram caption limit when posting from Grok Bot?
An Instagram caption is capped at 2,200 characters, and the limit is enforced when the post is queued rather than when it fires. Hermoso enforces it when the post is created or queued, so Grok Bot is told immediately rather than failing later when nobody is watching.
Can Grok Bot run Instagram ads as well as posting?
Yes, through the Meta campaign tree. Instagram placements are selected inside a Meta ad set. preview_meta_ad renders the real ad per placement before you spend.
Can Grok Bot post privately or as a draft to Instagram?
No. Instagram’s Content Publishing API publishes or does nothing. There is no unlisted, private or draft post. A published caption also cannot be edited; the only field Meta lets you change on a live post is whether comments are enabled. Deleting a post is supported, and covers ordinary posts, Stories, Reels and entire carousel albums. Hermoso refuses a visibility Instagram cannot honour at the moment you ask for it, rather than quietly publishing something weaker.
Can Grok Bot research Instagram before it posts?
Yes. search_meta_ads covers Instagram placements in the Meta Ad Library, and search_instagram searches public Reels by keyword.
