How to connect ClipSpeed to Grok Build
Add ClipSpeed as an HTTP MCP server in Grok Build's configuration, complete the sign-in, and the tools appear.
1 · Connect · about a minute
{
"mcpServers": {
"clipspeed": { "url": "https://api.clipspeed.ai/mcp" }
}
}ClipSpeed has not yet run an end-to-end check inside Grok Build. The server is standard MCP over HTTP; the configuration shape above is the common one and Grok Build's documentation is the reference for the file location.
2 · Then ask
- Add the clipspeed server with the URL to Grok Build's MCP configuration (see its docs for the file location).
- Start Grok Build; complete the ClipSpeed sign-in when prompted, or use an API key header.
- Ask it to list your channels.
- If the agent runs commands rather than MCP, the ClipSpeed CLI is in progress.
Verified terminal agents: Claude Code and Codex.

One connection powers every channel you run
Connect each platform to ClipSpeed once, through the platform's own sign-in. From then on Grok Build can post to any of them by name, and ClipSpeed publishes at the minute you set. Posting today: YouTube, TikTok, Instagram, X (Twitter) and LinkedIn. The badge on each platform tells you the truth about the rest.

Which way should I connect ClipSpeed to Grok Build?
The first row is the route this page documents. Every row reaches the same account, the same calendar and the same booking rules; they differ in how you sign in and what else is in the toolset.
| Method | How you connect | Auth | Toolset | Best for |
|---|---|---|---|---|
| MCP config (this page) | url in the MCP config | OAuth or key | Full | Grok Build users |
| ClipSpeed CLI + skill | In progress | API key | Scheduling, clipping | If MCP is unavailable |
| Claude Code or Codex | One command | OAuth | Full | Verified alternative |
The same server works with every other agent too: see the MCP server page and the AI agents overview.
Why use Grok Build for social media with ClipSpeed?
Grok Build brings the context: xAI's coding agent and CLI. ClipSpeed brings structured tools for every platform, the booking rules that keep an account healthy, and the two things no other scheduler's agent can do: cut the clips and generate the media in the same conversation.
Repo-aware posts
Release notes become posts within each platform's limit.
Clips attached
Clip the demo, attach the best.
Exact-or-refused
Slots are booked or refused with the next open one.
Clips from inside the tool call
Submit a video or a live stream, get back captioned 9:16 clips with a viral score, and book the best ones. The clipping step is a tool, not a separate product.
Image and video generation
Generate a product shot, a quote card or a short opener with ClipSpeed's models, see the credit price first, and post the hosted result with media_url.
Rules that run on the server
Caps, spacing, exact-or-refused booking, duplicate protection and per-platform limits are enforced when Grok Build books, so a hurried prompt cannot flood a platform or post the same thing twice.
What is Grok Build?
Grok Build is xAI's coding agent and command-line tool. It runs tasks in your project and can call MCP servers. With ClipSpeed added, it can clip a video, generate media and schedule posts.

How ClipSpeed works with Grok Build
Once connected, Grok Build sees every ClipSpeed tool the moment the sign-in completes: channels, platform rules, posts, analytics, clipping and generation. It chains them for you; the rules below are what keeps that safe.
- Connects over HTTP
- Reads platform rules
- Exact-or-refused booking
preview: true- Same tools everywhere
How booking works, whatever the client
- Exact or refused. A time you name is booked to the minute or refused with the reason and the next open slot. ClipSpeed never moves a booked post without asking.
- As soon as possible is placed and said. Leave the time out and the reply tells you exactly where the post landed.
- Preview books nothing.
preview: trueruns the whole booking, including caps, spacing and slot choice, and writes nothing. It is how a week gets planned before it is booked. - Limits are refused at booking, never trimmed at send time. The reply carries the real count so the fix is one edit.
- Pacing protects the account. Text posts on X are at least 30 minutes apart (ten a day); LinkedIn text is an hour apart (three a day); video uploads are two to four hours apart under your plan's daily cap.
- One piece of content goes to one platform once. The same text or the same file to the same platform is recognised as a duplicate and refused.
- Cancel is undoable for 72 hours in the ClipSpeed app. Copy can be edited while a post is still scheduled; the time cannot, by design.

# Rules
- Read platform_settings before composing; limits are refused, never trimmed.
- Preview a plan (preview: true) before booking; never skip the user's approval.
- A refused slot comes back with the next open one. Use it; never guess a time.
- One piece of content goes to one platform once.What Postiz-style schedulers cannot do
Cut the clips first
Grok Build does not need finished video to start. Hand it a YouTube link, a podcast, a stream VOD or a local export. ClipSpeed finds the moments, cuts them to 9:16 with word-by-word captions, scores each one 0 to 100 for shareability, and returns them in the same conversation. Grok Build picks by score, writes the caption from the transcript, and books the clips on YouTube, TikTok, Instagram, X (Twitter) and LinkedIn. Three tool calls, one approval, no download and no re-upload.
- Clips arrive with a title written from the hook, a transcript and a viral score, so the agent can choose and caption without watching the footage.
- Live streams can be clipped while they are still on air; the agent books the highlights for the next morning before the stream ends.
- Every clip is already hosted, so
schedule_posttakes its id directly. Nothing moves through your laptop.
submit_to_clipspeedPaste the link. ClipSpeed starts the job and returns a project id.check_clipsPoll with the project id. Back come the finished 9:16 clips with titles, transcripts, viral scores and preview links.schedule_postPass the clip id, the platforms, a caption and a time. Grok Build shows the plan with preview: true, you say yes, it books.generate_image or generate_videoDescribe the shot. ClipSpeed runs it on the model that fits (Seedance, Kling, Veo, Nano Banana Pro, GPT Image and others) and quotes the credits first.wait_for_generationReturns the hosted result link and a preview the agent can show you.schedule_post with media_urlThe result link goes straight into the booking. The caption, the time and the file are approved together.The other half nobody else has
Generate the image or video, then post it
A product shot for Instagram, a 16:9 announcement graphic for X, a six-second opener before a clip: Grok Build can make an image or a short video with ClipSpeed's image and video models and book the result in the same reply. There is no separate design tool, no export, no upload page. The generated file is hosted, so media_url is the only thing the booking needs.
- The price in credits is quoted before anything renders, within the per-generation and daily caps you set in Settings.
- Results are previewed in the conversation, so you approve the picture and the post at once.
- Images post as JPG, PNG or WebP up to 25 MB; video posts as MP4, MOV or WebM up to 1 GB.
Verification status
Grok Build is marked as the generic MCP route until ClipSpeed has run it end to end. If Grok Build in your version installs plugins rather than MCP servers, the ClipSpeed CLI and skill are the path, and they are in progress.
What can you ask Grok Build to do?
Anything the ClipSpeed tools expose: channels, posts, media, clips, generation and analytics. Four typical requests and what Grok Build does with each. Copy one and change the names.

Grok Build and ClipSpeed: frequently asked questions
How do I connect ClipSpeed to Grok Build?
Add ClipSpeed as an HTTP MCP server in Grok Build's configuration, complete the sign-in, and the tools appear. Add the clipspeed server with the URL to Grok Build's MCP configuration (see its docs for the file location). Start Grok Build; complete the ClipSpeed sign-in when prompted, or use an API key header. Nothing else is installed, and the same account you use in the ClipSpeed app is the one Grok Build books into.
Do I need a paid ClipSpeed plan to schedule from Grok Build?
Scheduling needs an active ClipSpeed plan or the $1 trial, and it is included on every paid plan at no extra cost. Grok Build itself is billed by xAI under your own account. Connect during the trial, book a few posts, and the plan screen in ClipSpeed takes it from there.
Is Grok Build the same as Grok Bot?
No. Grok Build: terminal, coding agent. Grok Bot: cloud, always on, routines on a cloud computer. Grok: x and grok.com, the chatbot. All of them reach the same ClipSpeed account and the same calendar; this page covers Grok Build.
What can Grok Build do with ClipSpeed?
List your connected channels, read each platform's rules, write posts within those rules, schedule or preview them, edit or cancel what is scheduled, and read the numbers after a post goes out. It can also cut a video or a live stream into captioned 9:16 clips with a viral score, generate images and video, and book the results. Today that posts to YouTube, TikTok, Instagram, X (Twitter) and LinkedIn; text-only posts go to X (Twitter) and LinkedIn.
Will posts go out while I am away?
Yes. Once Grok Build books a post, ClipSpeed holds it and publishes at the scheduled minute whether or not the session is open. For fully unattended runs, pair ClipSpeed with a headless agent such as Claude Code or Codex.
Does Grok Build need my social media passwords?
No. You connect each platform to ClipSpeed once through that platform's own sign-in; ClipSpeed never sees the password and Grok Build never sees the platform at all. Grok Build authenticates to ClipSpeed over OAuth, so no key is pasted anywhere, and it can only reach channels already connected in your account. Keep Grok Build's confirmation step on for anything that goes live.
Which platforms can Grok Build post to through ClipSpeed?
Today: YouTube, TikTok, Instagram, X (Twitter) and LinkedIn. Next on the rail: Facebook, Threads, Bluesky and Pinterest. 21 more platforms, from Telegram and Discord to Reddit and WordPress, are described on their pages with an honest status badge and are not bookable until that badge changes. Each platform below has its own Grok Build guide with a settings reference and the limits that apply.
Grok Build does not show the ClipSpeed tools. What should I check?
Confirm the connection finished: the ClipSpeed sign-in (or the API key header) has to complete before the tool list is advertised. Then start a fresh session, since servers load at startup. If a channel is missing rather than a tool, connect the platform in ClipSpeed first and ask Grok Build to list channels again.
Has ClipSpeed verified Grok Build?
Not yet. The badge changes when we have.
Is Grok Build the same as Grok?
No. Grok is the chatbot on X and grok.com; Grok Build is the coding agent for the terminal.
