Post to X (Twitter) from Cursor
Cursor can post text, images and video on X (Twitter) through ClipSpeed. Add the ClipSpeed server with one config block, sign in, and then ask Cursor to post text, images and video, pick the time, and apply X (Twitter)'s settings, without leaving the Cursor editor's Agent.
Keep a human in the loop: Cursor shows the plan and asks before anything is public. Posting today: YouTube, TikTok, Instagram, X (Twitter) and LinkedIn.

How to post X (Twitter) from Cursor
Cursor reads MCP servers from a JSON file. Add the block, open Cursor Settings → MCP, click the sign-in for clipspeed, and the Agent has the tools. Connect X (Twitter) in ClipSpeed, then describe the post. Setup takes about a minute.
# One-time setup: .cursor/mcp.json (project) or ~/.cursor/mcp.json (global)
{
"mcpServers": {
"clipspeed": { "url": "https://api.clipspeed.ai/mcp" }
}
}
# Then ask Cursor:
> Post 'Shipped: scheduled posts from any AI agent. Details in the thread' to X
Cursor: Preview — nothing booked yet. X (Twitter) — text only. Book it?Cursor shows the tools under Settings → MCP once the server connects. If the list is empty, check the JSON and restart Cursor. ClipSpeed has not yet seen a real Cursor session connect; the setup is Cursor's documented MCP route and the URL is the same as every verified client.
- Create .cursor/mcp.json in the project (or ~/.cursor/mcp.json for every project) with the block shown.
- Open Cursor Settings → MCP. clipspeed appears; click to authenticate and approve the ClipSpeed sign-in.
- Open the Agent panel and ask it to list your channels.
- Connect X (Twitter) in the ClipSpeed app, or ask Cursor for a connect link: it is private, valid for ten minutes, and X (Twitter) signs you in itself.

What can Cursor do on X (Twitter)?
On X (Twitter), Cursor can post text, images and video with X's 280-character rule applied at booking. Every booking runs through the same rules as the ClipSpeed app.
Text, Image and Video posts
X (Twitter) takes text, image and video through ClipSpeed. Text-only posts work today. Video: MP4, MOV or WebM up to 1 GB by public link, or a finished ClipSpeed clip. Image: JPG, PNG, WebP or GIF up to 25 MB by public link.
280 characters, checked at booking
X (Twitter)'s own arithmetic, with every link counted as 23. Too long is refused with the real count, never trimmed at send time.
Exact time or refused
Name the minute and Cursor books it, or you are told why not and offered the next open slot. A booked X (Twitter) post is never moved behind your back.
Preview before anything posts
preview: true runs the whole booking and writes nothing. Cursor shows the plan, with each slot and the day's remaining cap, and books only on your yes.
Clips cut in the same chat
Submit a video or stream link, get captioned 9:16 clips with a viral score, and post the best as native video on X (Twitter). No download, no re-upload.
Pacing and numbers
Text and image posts on X (Twitter) are at least 30 minutes apart, up to 10 a day. Video on X (Twitter) is at least 2 hours apart, up to 4 a day under your plan. After a post goes out, Cursor can read back views and engagement where X (Twitter) provides them.
How does Cursor post to X (Twitter) through ClipSpeed?
You describe what you want in plain language and Cursor makes the ClipSpeed calls. A typical conversation has three beats.
Find your X (Twitter) channel
Ask Cursor whether X (Twitter) is connected. It calls list_channels and reads platform_settings, so it also knows what X (Twitter) accepts and the limits before you write a word.
Compose within the rules
Describe the post. Cursor drafts within X (Twitter)'s limits, counting links as 23; mention a clip or a file and it attaches it.
Schedule or publish
Name a time, or say now. The slot is booked exactly or refused with the next open one, and the reply carries the id you can cancel or edit by.
X (Twitter) settings reference
These are the schedule_post fields that apply to X (Twitter). Mention any of them in plain language and Cursor sets them; the server checks them at booking.
| Field | Type | Required | What it does on X (Twitter) |
|---|---|---|---|
platforms | string[] | Yes | Include "x". Up to ten platforms per call; each books its own slot. |
text | string | Yes for a text post | Up to 280 characters. Every URL counts as 23 no matter its length; the count is checked at booking. |
hashtags | string[] | No | Appended to the text and counted toward 280. |
media_kind | text | image | video | No | Detected from the file when omitted; text when there is no file. |
clip_id or media_url | string | No | A ClipSpeed clip, or a public https link to an image up to 25 MB or a video up to 1 GB. Leave both out for a text post. |
scheduled_at | ISO 8601 | No | Exact or refused with the next open slot. Omit to post as soon as possible. |
preview | boolean | No | Plan only; returns each slot and the day's remaining cap. |
Common X (Twitter) configurations
Ask Cursor for any of these and it applies the matching settings.

Example prompts for X (Twitter) in Cursor
Type these into the Cursor editor's Agent, or pass one to terminal in a script. Cursor calls ClipSpeed and confirms before publishing.
Post X (Twitter) with a scheduled time
Post 'Shipped: scheduled posts from any AI agent. Details in the thread' to X. Keep the text under 280 characters with links counted as 23. Preview first.
Cut the clips, then post the best
Clip this link, keep the top three by viral score, and schedule them to X (Twitter) at 11am, 3pm and 7pm tomorrow. Show me the plan before booking.
From a script with Cursor
cursor-agent -p "Summarise the changes since the last git tag as one X (Twitter) post under 280 characters. Schedule it via ClipSpeed for today at 10am; preview first and book if nothing is refused."
X (Twitter) limits and gotchas to know
X (Twitter) enforces a few rules that Cursor and ClipSpeed respect automatically, but knowing them helps you phrase requests.
- 280 characters, with every link counted as 23. ClipSpeed uses X's arithmetic at booking, so a post that is 290 characters by your editor's count but 275 by X's is accepted, and the reverse is refused with the real number.
- Threads are not a single call. Ask the agent for separate posts or wait for thread support; the page does not claim threads because they do not post today.
- Text posts are spaced 30 minutes apart and capped at ten a day per account; video posts are two hours apart under your plan's video cap. The reply names the next open slot when a time is taken.
- Hashtags count toward the 280. Ask for one or two, not a wall.
- X is one of the two platforms that take text-only posts through the agent tools today (LinkedIn is the other). Everything else needs a clip, an image or a video.
| Rule | X (Twitter) |
|---|---|
| Accepts | Text, Image, Video (text-only posts work today) |
| Text limit | 280 characters; every link counts as 23 |
| Title | No title field |
| Links in the caption | Kept and clickable; every link counts as 23 characters regardless of length |
| Pacing | Text and image posts on X (Twitter) are at least 30 minutes apart, up to 10 a day. Video on X (Twitter) is at least 2 hours apart, up to 4 a day under your plan. |
| Formats | Image: JPG, PNG, WebP or GIF up to 25 MB by public link. Video: MP4, MOV or WebM up to 1 GB by public link, or a finished ClipSpeed clip. Aspect: any; 16:9 or 1:1 reads best in the timeline |

What Postiz-style schedulers cannot do
Cut the clips first
Cursor 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. Cursor picks by score, writes the caption from the transcript, and books the clips on X (Twitter). 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. Cursor 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 on X (Twitter). 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: Cursor 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.
What is Cursor?
Cursor is the AI code editor built on VS Code. Its Agent runs multi-step tasks in your project, runs commands and calls MCP tools. With ClipSpeed in Cursor's MCP settings, the Agent can clip a video, generate media and schedule posts from inside the editor, and the Cursor CLI can do the same from a script.
How ClipSpeed works with Cursor
- Cursor reads .cursor/mcp.json and connects to the ClipSpeed server; sign in under Settings → MCP
- The Agent reads

X (Twitter) and Cursor: frequently asked questions
How do I post to X (Twitter) from Cursor?
Create .cursor/mcp.json in the project (or ~/.cursor/mcp.json for every project) with the block shown. Open Cursor Settings → MCP. clipspeed appears; click to authenticate and approve the ClipSpeed sign-in. Connect X (Twitter) in ClipSpeed (or ask Cursor for a connect link; it is private and valid for ten minutes), then describe the post in plain language. Cursor reads the X (Twitter) rules, drafts within them, shows the plan and books on your yes.
What can Cursor post to X (Twitter) through ClipSpeed?
Post text, images and video with X's 280-character rule applied at booking. X (Twitter) takes text, image and video posts, and text-only posts work today. Text is limited to 280 characters, with every link counted as 23.
Which X (Twitter) settings can Cursor control?
The fields in the settings reference above: text, hashtags, media_kind, clip_id or media_url, scheduled_at, preview. Mention any of them in plain language ("unlisted", "tomorrow at 9", "preview first") and Cursor sets the matching field before it books.
Do I need a X (Twitter) API key or developer account?
No. You connect X (Twitter) to ClipSpeed once through X (Twitter)'s own sign-in, and Cursor talks to ClipSpeed over OAuth. No X (Twitter) developer key, bearer token or password is pasted anywhere.
How many X (Twitter) posts a day can Cursor schedule?
Text and image posts on X (Twitter) are at least 30 minutes apart, up to 10 a day. Video on X (Twitter) is at least 2 hours apart, up to 4 a day under your plan. When a time is taken, the booking is refused with the next open slot rather than moved. Ask for preview to see a day's plan and the remaining cap before anything is booked.
Can Cursor post to X (Twitter) from a script or a cron job?
Yes. Cursor's headless mode (terminal) runs one prompt and exits, and the ClipSpeed server registered on that machine does the booking. On a runner with no browser, authenticate with a ClipSpeed API key header. Keep preview on so the run reports a plan before it books.
Is posting to X (Twitter) from Cursor different from Windsurf?
The booking is identical: the same rules, the same calendar, the same refusals. What differs is where you work. Cursor: the cursor editor; cursor-agent on the command line. Windsurf: windsurf editor, cascade agent; same url.
