Publish notes to Nostr from Cursor
Cursor can publish notes on Nostr through ClipSpeed. Add the ClipSpeed server with one config block, sign in, and then ask Cursor to publish notes, pick the time, and apply Nostr's settings, without leaving the Cursor editor's Agent. Nostr is on the roadmap on ClipSpeed's rail; this page describes how it works and says so.
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 publish notes Nostr 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 Nostr 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:
> Publish a note about the launch at 9am
Cursor: Preview — nothing booked yet. Nostr — text. 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 Nostr in the ClipSpeed app, or ask Cursor for a connect link: it is private, valid for ten minutes, and Nostr signs you in itself.

What can Cursor do on Nostr?
On Nostr, Cursor can publish signed notes with linked media to your relays. Every booking runs through the same rules as the ClipSpeed app.
Text, Image and Video posts
Nostr takes text, image and video through ClipSpeed. Video: linked by URL. Image: linked by URL.
Limits checked at booking
Nostr notes have no protocol limit; most clients truncate near 1,000 characters. Titles are optional.
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 Nostr 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 Nostr. No download, no re-upload.
Pacing and numbers
Planned: Text posts on Nostr are at least 30 minutes apart, up to 10 a day. After a post goes out, Cursor can read back views and engagement where Nostr provides them.
How does Cursor post to Nostr through ClipSpeed?
You describe what you want in plain language and Cursor makes the ClipSpeed calls. A typical conversation has three beats.
Find your Nostr channel
Ask Cursor whether Nostr is connected. It calls list_channels and reads platform_settings, so it also knows what Nostr accepts and the limits before you write a word.
Compose within the rules
Describe the post. Cursor drafts within Nostr's limits; 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.
Nostr settings reference
These are the schedule_post fields that apply to Nostr. Mention any of them in plain language and Cursor sets them; the server checks them at booking. Fields marked planned land with the Nostr release.
| Field | Type | Required | What it does on Nostr |
|---|---|---|---|
platforms | string[] | Yes | Include "nostr". Up to ten platforms per call; each books its own slot. |
text | string | Yes | The note. No protocol limit; keep it short because clients truncate. |
relays | string[] | Planned | Relays to publish to; defaults to the ones on your connected profile. |
media_url | string | No | A public link; Nostr embeds media by URL. |
scheduled_at | ISO 8601 | No | Exact or refused with the next open slot. |
preview | boolean | No | Plan only. |
Common Nostr configurations
Ask Cursor for any of these and it applies the matching settings.

Example prompts for Nostr 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.
Publish notes Nostr with a scheduled time
Publish a note about the launch at 9am. Preview first.
Cut the clips, then post the best
Clip this link, keep the top three by viral score, and schedule them to Nostr 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 Nostr post. Schedule it via ClipSpeed for today at 10am; preview first and book if nothing is refused."
Nostr limits and gotchas to know
Nostr enforces a few rules that Cursor and ClipSpeed respect automatically, but knowing them helps you phrase requests.
- Notes are signed with your key. ClipSpeed will use a signing method that never asks for your private key in chat; details land with the release.
- There is no protocol character limit, but clients truncate long notes, so short wins.
- Media is a URL in the note, not an upload; ClipSpeed clips are already hosted.
- Nostr is on ClipSpeed's roadmap, not the next rail. Bookings are refused plainly until it posts.
- A note is published to each relay you choose; a relay that is down simply misses it.

|---|---|

| Text limit | Nostr notes have no protocol limit; most clients truncate near 1,000 characters |

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 Nostr. 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 Nostr. 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

Nostr and Cursor: frequently asked questions
How do I publish notes to Nostr 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 Nostr 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 Nostr rules, drafts within them, shows the plan and books on your yes. Nostr is on the roadmap; until the badge changes, the booking is refused with a plain message.
What can Cursor post to Nostr through ClipSpeed?
Publish signed notes with linked media to your relays. Nostr takes text, image and video posts.
Which Nostr settings can Cursor control?
The fields in the settings reference above: text, relays, 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 Nostr API key or developer account?
No. You connect Nostr to ClipSpeed once through Nostr's own sign-in, and Cursor talks to ClipSpeed over OAuth. No Nostr developer key, bearer token or password is pasted anywhere.
How many Nostr posts a day can Cursor schedule?
Planned: Text posts on Nostr are at least 30 minutes apart, up to 10 a day. 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 Nostr 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 Nostr 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.
