# Schedule a tweet on X (Twitter) from an AI agent

Automatically schedule a tweet on X (Twitter) from an AI agent on x.com. Schedule a post on X (Twitter) to be sent at a later date and time, instead of posting now. Takes the text (280 characters at most) and sendAt, a local time with no offset, read in the account's own display timezone, from about 10 minutes to about 18 months ahead. Returns the scheduled_id, the text and send_at.

## Run it

Ask an AI agent connected to Reduck over MCP (`https://mcp.reduck.ai/mcp`) to run `reduck/x.com/schedule_tweet`, or run it from a terminal:

```bash
npx @reduck-ai/cli@latest run --script reduck/x.com/schedule_tweet
```

## Input

- `text` (string, required): The post's text. X caps this at 280 characters for a standard (non-subscriber) account.
- `sendAt` (string, required): When to send the post, as an ISO-8601 datetime (e.g. "2026-09-15T14:30:00"). X's composer only offers minute precision and reads/writes it in the account's own display timezone, not UTC — pass a naive local time (no offset) matching that timezone. X also refuses times inside the next ~10 minutes and more than ~18 months out.

## Output

- `text` (string, required)
- `send_at` (string, required)
- `scheduled_id` (string, required)
