OAuth in one click · Post, thread, schedule

Schedule X posts from your agent, or the calendar

Connect X once. Then post now, queue a thread, or fill next week — driven by Claude Code, Codex, or any MCP client, or clicked together in the Console. Groniz owns the OAuth, the character limits, and the delivery.

On X, specifically

The bits X makes hard, handled

280 characters, or 4,000

Groniz counts as you write — 280 on a standard profile, 4,000 once the account is set to Premium — and stops the post at the limit instead of letting X reject it later.

Threads post in order, as one unit

Give it a root post and its continuations. Groniz publishes the root, then chains each reply to the one before it, so the thread lands in sequence instead of racing itself.

Queue a week, not an evening

Drop posts onto the calendar and give X a real cadence. Nothing sits in a reminders app waiting for you to be at a keyboard at 9am.

Everything else

Run your whole X presence

Queue, draft, sign off, measure. Whatever you do by hand here, your agent can do over MCP or the CLI.

The X queue, beside every other one

X rarely runs alone. Put its cadence on the same calendar as the rest, and reuse a post that worked on X wherever else it fits — Groniz refits the text to each network’s own limit on the way out.

Drafting, when the hook won’t come

Describe the point you want to make and get a post — or a whole thread, split into its continuations — back to edit. It is a starting draft, not a send button: nothing leaves until you say so.

A second pair of eyes on the timeline

X is unforgiving of the post you can’t unsend. Give teammates their own roles, and hold anything you want checked behind an approval until the right person signs it off.

See what actually landed

Impressions, likes, retweets, replies, quotes and bookmarks, per post — read in the same place you scheduled it, so the hooks worth repeating are easy to spot.

Agent-driven

X is just a target for your agent

Install the Groniz skill and your agent — Claude Code, Codex, ChatGPT, any MCP client — learns to drive X for you. You keep the judgement; it keeps the keys out of your scripts.

You Post the thread I drafted, and only let people I follow reply.

groniz posts:create \
  -c "1/ Why we built this" -c "2/ How it works" -c "3/ Try it" \
  -d 2000 \
  --settings '{"who_can_reply_post":"following"}' \
  -s "2026-07-18T09:00:00Z" -i "x-id"

Each -c is one post in the chain; -d spaces them, and who_can_reply_post sets the reply control X is known for.

X questions

Scheduling X, answered

What does Groniz ask for when I connect X?+
You authorize Groniz on X itself, granting it read and write access so it can publish on your behalf. Nothing else is requested, the authorization is tied to that one account, and you can revoke it from your X settings at any time without touching Groniz.
Can I schedule a whole thread, not just one post?+
Yes. A thread is a root post plus its continuations. Groniz publishes the root first, then chains each continuation as a reply to the previous one, in order, so the thread reads correctly on your timeline.
What can my agent actually do on X?+
Publish a post immediately, queue one for a time you choose, and send a full thread as a single instruction. It works the same over MCP and the CLI, and the agent authenticates to Groniz with an API key — the X authorization stays on the Groniz side, so a leaked script key never becomes a leaked X account.
Does it handle the 280-character limit for me?+
Yes. Groniz counts as you write and stops you at the limit for that account — 280 characters on a standard profile, or 4,000 when the account is set to Premium — so the post fails in the editor rather than at X.
Can I attach images or video to a scheduled X post?+
Yes. Upload the media in Groniz and attach it to the post, scheduled or immediate. X’s own per-post limits apply — up to four images, or a single video.
Do I need my own X developer app?+
No. Connecting X from Groniz is a normal authorization flow on x.com — there are no API keys to create, no developer portal to visit, and no tier to pick before you can schedule your first post.
