The fastest way to clip and post videos to X is to have Grok Bot run OpusClip for you. Connect OpusClip to Grok Bot over MCP, give the bot a long video, and it will get back captioned clips, pick the ones that fit your account, write X posts for each, and schedule them after you approve. It works for podcasts, livestreams, interviews, product demos, and any long video with a few moments worth sharing.

This guide covers the setup, a copy-paste instruction, how to shape clips for X, and the guardrails we recommend.

Why Grok Bot for X posting

Grok Bot is built to keep working in the background, sign in to the tools you already use, and come back when something needs approval. That suits X, where consistency matters and the best-performing accounts post often. Grok Bot X posting works best when the bot manages the calendar and a video tool does the editing, because a general agent cannot rank the best moments in a long recording or time captions to each word on its own.

OpusClip handles that part. It analyzes the whole video, ranks the strongest moments, adds captions, and can schedule clips to X (in beta) as well as YouTube, TikTok, Instagram, LinkedIn, and more.

What you need

• Grok Bot: available on SuperGrok, SuperGrok Plus, SuperGrok Heavy, and Cursor Pro, Pro+, Ultra, and Teams plans, on desktop and iOS.
• OpusClip Pro, Max, or Business: needed to run clipping and scheduling tools.
• Your X account connected in OpusClip: link it once in OpusClip's social accounts.
• A long video: a YouTube or Vimeo link, a Zoom recording, or a file in Google Drive or Dropbox.

Step 1: Connect OpusClip to Grok Bot

If OpusClip appears in your bot's Plugins list, choose Add and then Authenticate. Otherwise, add it as a custom MCP server in chat:

1. Open a chat with your bot and type: Add a custom MCP server called OpusClip at https://mcp.opus.pro/mcp
2. The bot shows the name and URL and asks you to confirm. Check the URL, then choose Add it.
3. The bot posts a connect card in the chat. Choose Authorize and sign in to OpusClip in your browser.
4. Type @ in the chat to attach OpusClip to a task.

Full details are in our guide to add the OpusClip MCP server to Grok Bot.

Step 2: Decide what a good X clip looks like

• Short and self-contained: one idea per clip, no setup needed from earlier in the video.
• Front-loaded: the strongest line in the first few seconds.
• Captioned: many people scroll with sound off.
• Format: vertical works well on mobile; square or landscape can suit desktop-heavy audiences. OpusClip can reframe to 9:16, 1:1, or 16:9.
• Post copy that adds something: a take, a question, or a number, not just the clip title.

Step 3: Give the bot the job

Paste this and edit the brackets:

Using OpusClip, clip this video: [link]. Keep the 5 strongest clips under 60 seconds with captions. Prefer bold opinions, surprising numbers, and clear how-to moments. For each clip, write an X post under 200 characters that makes a point rather than describing the clip. Show me the clips and posts. Do not post or schedule anything until I approve.

OpusClip needs a few minutes for a long video. The bot checks back on its own and reports when the clips are ready.

Step 4: Review, edit, and approve

Reply in plain language and the bot applies the changes through OpusClip:

• "Start clip 3 at the question." Trims the opening.
• "Remove filler words from all clips." Tightens pacing.
• "Make clip 1 square." Changes the frame for desktop viewers.
• "Rewrite post 2 as a question." Adjusts the copy.

Step 5: Schedule to X

Once you approve, the bot schedules the clips to X through OpusClip:

Schedule the approved clips to X, one per day at 9am and 5pm Eastern, alternating, starting tomorrow. Send me the schedule when done.

You can add YouTube Shorts, TikTok, LinkedIn, and other connected accounts in the same step so one video feeds every channel.

Turn it into a routine

Because Grok Bot keeps working around the clock, you can make this standing:

Every weekday morning, check [my YouTube channel] for new videos. Clip each new one with OpusClip and send me X post drafts for approval.

That is how you post video clips to X automatically without giving up control of what goes out. Grok Bot also learns your preferences over time, so drafts should need fewer edits.

X video clips from YouTube: what works best

• Podcasts and interviews: strong opinions and stories travel well on X.
• Livestreams: clip the highlights while the conversation is still going.
• Product demos: one feature per clip, with a link in the reply.
• Talks and panels: single quotable lines with captions.
• Your back catalog: old videos with proven ideas. See how TFTC turned old videos into new revenue on X for what that looks like in practice.

Using Grok Bot as an AI agent for X growth

Clips are one part of growth on X. Once the video workflow runs, you can give the same bot follow-up jobs: summarize replies to your latest clip, suggest which topics to clip next based on what performed, and flag posts worth responding to. Keep the video work in OpusClip and the judgment calls with you.

Guardrails

• Always approve posts: the OpusClip MCP server posts and schedules as soon as those tools are called, so tell the bot never to post or schedule without your approval.
• Check facts in clips: numbers and claims pulled out of context can mislead.
• Mind the cap: OpusClip API access includes 15 hours or 900 credits per workspace per month, and four projects at a time.
