# How to schedule an X thread with an AI assistant

> Use schedule_thread or publish_thread_now with one X account id & between 2 and 25 tweets. Check get_x_cap_usage before a large batch, since X has a monthly posting cap. These tools are for X threads, not Meta Threads.

Updated: 2026-10-05.

## Two tools, one job

DunSocial's MCP has `schedule_thread` for a thread at a future time & `publish_thread_now` for one right away. Both post an X (Twitter) thread.

They are not for Meta's Threads app. That's a different platform with its own account type.

## The rules

- Exactly one X account, passed as a single social account id
- Between 2 & 25 tweets
- Each tweet has content & can have its own media
- Scheduling also needs a time

Get the account id from `list_social_accounts`. A handle isn't an id.

## An example request

A plain-language ask is enough, as long as it names the account & the time:

> Schedule a 4-tweet X thread for this afternoon on my main X account, explaining how our scheduling queue works.

The assistant drafts the tweets, picks the right account id & calls `schedule_thread` with an ISO timestamp.

## Check the cap first

X has a monthly posting cap in DunSocial. Reaching it makes further scheduling or publishing to X return a rate-limit style error.

Ask the assistant to call `get_x_cap_usage` before a large batch so a long thread doesn't fail partway through the plan.

## Character limits

Each tweet is checked against the X limit, which is 280 characters, or 25,000 when the connected account has X Premium. Long threads are where the limit is easiest to hit by accident.

Run `validate_post` on the content before scheduling. The tool is a dry run, so it costs nothing & shows exactly which tweet is too long.

DunSocial applies the Premium limit only when the connected X account actually has Premium, so don't assume it for every account.

## Review before it goes out

A scheduled thread appears on the DunSocial calendar like any other post, so you can read it, reorder a tweet or cancel it before the time arrives.

For anything public under your name, schedule instead of publishing now. It gives you a window to read what the assistant wrote.
