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 Threads, and what Threads 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 Threads 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 Threads tools Grok Bot gets
post_to_meta: publishes text, an image or a video withtarget: "threads", optionally geotagged.schedule_post: queues it alongside every other channel.list_threads_posts / threads_insights: what you have posted, and how each one did.list_threads_replies / reply_to_thread / hide_thread_reply: read the replies, answer as the brand, hide what does not belong.list_threads_mentions: who is talking about you.search_threads_keyword / search_threads_locations: keyword search and the location ids a geotag needs.delete_thread: removes a post.
Threads is the channel where Hermoso goes furthest past publishing. Beyond posting there is a full read-and-respond surface (replies, mentions, keyword search and per-post insights), which makes it usable as a listening channel as well as an outlet. Note that Threads is a separate OAuth grant from Facebook even though it shares the Page.
Threads limits worth knowing before you automate anything
| Text | A Threads post is capped at 500 characters, the tightest here apart from X. 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. “Threads has no unlisted, private or draft post.” A Threads post exists publicly or not at all. |
| Carousel | 2 to 20 slides, images and video mixed. Both bounds are Meta’s own words, quoted in the table that enforces them: “Carousels must have at least 2” items, and “no more than 20 total images, videos, or a mix of the two.” That makes Threads the most generous mixed-media carousel of any channel here. |
| Which account | pageId. The same connected Page identity carries Facebook, Instagram and Threads. |
Try it in Grok Bot
Ask for it in ordinary language. These are plain sentences, not a DSL:
“Every morning, read my mentions and replies, tell me the question people keep asking, and draft one post under 500 characters answering it.”
That walks get_brand → generate_text → post_to_meta (target: "threads") → list_threads_replies. 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 Threads: the part that bites
Split the loop along the line the tools already draw. Mentions, replies, keyword search and insights have no public effect, so a Bot can do the entire listening job unattended and stop at the draft. The 500-character cap is enforced when the post is queued rather than when it fires, so an over-long batch fails immediately instead of at 9am on a day you are not watching.
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 Threads before you post
search_threads searches public Threads by keyword through the research surface, and search_threads_keyword does the same through your connected Threads account. There is no Threads ad library, because there are no Threads ads to archive.
The paid half
There is no Threads ads product in Hermoso, and it would be wrong to imply one. Threads here is an organic channel: publish, read, reply, measure. The paid tools cover Meta (Facebook and Instagram), Google Ads, Microsoft Advertising, Reddit Ads, LinkedIn, Pinterest, X Ads, TikTok Ads, Snapchat Ads, ChatGPT Ads, Apple Search Ads and AppLovin Ads.
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 Threads?
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 Threads, plus the ones that research the ads already running in your market and render the creative in the first place.
How do I connect Threads 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 Threads inside Hermoso under Settings → Connectors, which is an OAuth consent screen in a browser. After that Grok Bot publishes to Threads as an ordinary tool call.
Can Grok Bot post a carousel to Threads?
Yes, 2 to 20 slides, images and video mixed. Both bounds are Meta’s own published numbers for the Threads API. Grok Bot calls the same publish tool either way, and a channel that cannot carry a carousel is refused with the real reason attached.
Can Grok Bot research Threads before it posts?
Yes. search_threads searches public Threads by keyword through the research surface, and search_threads_keyword does the same through your connected account.
Does Grok Bot need my Threads password?
No. You connect Threads to Hermoso once through an OAuth consent screen in a browser, and Grok Bot then reaches it as a tool call. Linking an account is the one step that is not headless; nothing after it needs a password, and no credential is ever handed to the model.
Can Grok Bot run Threads ads as well as posting?
No. There is no Threads ads product in Hermoso. Threads here is organic: publish, read replies and mentions, answer, and measure.
