Post to Bluesky from GitHub Copilot
GitHub Copilot can post to Bluesky on Bluesky through ClipSpeed. Add the ClipSpeed server with one config block, sign in, and then ask GitHub Copilot to post to Bluesky, pick the time, and apply Bluesky's settings, without leaving VS Code's agent mode and the Copilot CLI. Bluesky is coming next on ClipSpeed's rail; this page describes how it works and says so.
Keep a human in the loop: GitHub Copilot shows the plan and asks before anything is public. Posting today: YouTube, TikTok, Instagram, X (Twitter) and LinkedIn.

How to post Bluesky from GitHub Copilot
VS Code reads MCP servers from .vscode/mcp.json. Add the entry, start the server from the editor, sign in, and agent mode has the tools. Connect Bluesky in ClipSpeed, then describe the post. Setup takes about a minute.
# One-time setup: .vscode/mcp.json
{
"servers": {
"clipspeed": { "type": "http", "url": "https://api.clipspeed.ai/mcp" }
}
}
# Then ask GitHub Copilot:

GitHub Copilot: Preview — nothing booked yet. Bluesky — text under 300. Book it?ClipSpeed has not yet run an end-to-end check inside Copilot. The server is standard MCP over HTTP, which VS Code's agent mode supports.
- Create .vscode/mcp.json in the workspace with the block shown.
- Open the file; VS Code shows a Start action above the server. Start it and approve the ClipSpeed sign-in.
- Open Copilot Chat in agent mode, confirm clipspeed is in the tools picker, and ask it to list your channels.
- Connect Bluesky in the ClipSpeed app, or ask GitHub Copilot for a connect link: it is private, valid for ten minutes, and Bluesky signs you in itself.
What can GitHub Copilot do on Bluesky?
On Bluesky, GitHub Copilot can post 300-character text, images and short video to Bluesky. Every booking runs through the same rules as the ClipSpeed app.
Text, Image and Video posts
Bluesky takes text, image and video through ClipSpeed. Video: MP4 up to three minutes on Bluesky. Image: JPG or PNG; up to four images per post on Bluesky, one through the first release.
300 characters, checked at booking
Bluesky's own arithmetic. Too long is refused with the real count, never trimmed at send time.
Exact time or refused
Name the minute and GitHub Copilot books it, or you are told why not and offered the next open slot. A booked Bluesky post is never moved behind your back.
Preview before anything posts
preview: true runs the whole booking and writes nothing. GitHub Copilot 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 Bluesky. No download, no re-upload.
Pacing and numbers
Planned: Text and image posts on Bluesky are at least 30 minutes apart, up to 10 a day. Video on Bluesky is at least 4 hours apart, up to 4 a day under your plan. After a post goes out, GitHub Copilot can read back views and engagement where Bluesky provides them.
How does GitHub Copilot post to Bluesky through ClipSpeed?
You describe what you want in plain language and GitHub Copilot makes the ClipSpeed calls. A typical conversation has three beats.
Find your Bluesky channel
Ask GitHub Copilot whether Bluesky is connected. It calls list_channels and reads platform_settings, so it also knows what Bluesky accepts and the limits before you write a word.
Compose within the rules
Describe the post. GitHub Copilot drafts within Bluesky'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.
Bluesky settings reference
These are the schedule_post fields that apply to Bluesky. Mention any of them in plain language and GitHub Copilot sets them; the server checks them at booking. Fields marked planned land with the Bluesky release.
| Field | Type | Required | What it does on Bluesky |
|---|---|---|---|
platforms | string[] | Yes | Include "bluesky". Up to ten platforms per call; each books its own slot. |
text | string | Yes for a text post | Up to 300 characters (graphemes). Links are clickable. |
hashtags | string[] | No | Appended; they count toward 300. |
media_kind | text | image | video | No | Detected from the file when omitted. |
clip_id or media_url | string | No | A ClipSpeed clip or a public link to an image or a video up to three minutes. |

From a script with GitHub Copilot
copilot -p "Summarise the changes since the last git tag as one Bluesky post under 300 characters. Schedule it via ClipSpeed for today at 10am; preview first and book if nothing is refused."
Bluesky limits and gotchas to know
Bluesky enforces a few rules that GitHub Copilot and ClipSpeed respect automatically, but knowing them helps you phrase requests.
- 300 characters per post, counted in graphemes. Longer is refused at booking with the count.
- Video on Bluesky is capped at three minutes by the network. ClipSpeed clips fit; a long upload does not.
- Bluesky allows four images per post; the first release posts one.
- Bluesky is the next rail. Until it posts, bookings are refused plainly and the badge says Coming soon.
- Planned pacing: ten text or image posts a day 30 minutes apart, video four hours apart.
| Rule | Bluesky |
|---|---|
| Accepts | Text, Image, Video |
| Text limit | 300 characters |
| Title | No title field |
| Links in the caption | Kept and clickable |
| Pacing | Planned: Text and image posts on Bluesky are at least 30 minutes apart, up to 10 a day. Video on Bluesky is at least 4 hours apart, up to 4 a day under your plan. |
| Formats | Image: JPG or PNG; up to four images per post on Bluesky, one through the first release. Video: MP4 up to three minutes on Bluesky. Aspect: any |
| Status | Coming next on ClipSpeed's rail; bookings are refused with a plain message until then |
What Postiz-style schedulers cannot do
Cut the clips first
GitHub Copilot 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. GitHub Copilot picks by score, writes the caption from the transcript, and books the clips on Bluesky. 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. GitHub Copilot 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 Bluesky. 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: GitHub Copilot 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 GitHub Copilot?
GitHub Copilot's agent mode in VS Code runs multi-step tasks in your workspace and calls MCP tools; the Copilot CLI does the same in a terminal. With ClipSpeed added as an HTTP MCP server, Copilot can clip a video, generate media and schedule posts to your connected platforms.
How ClipSpeed works with GitHub Copilot
- VS Code starts the server from .vscode/mcp.json and handles the OAuth sign-in
- Agent mode reads

Bluesky and GitHub Copilot: frequently asked questions
How do I post to Bluesky from GitHub Copilot?
Create .vscode/mcp.json in the workspace with the block shown. Open the file; VS Code shows a Start action above the server. Start it and approve the ClipSpeed sign-in. Connect Bluesky in ClipSpeed (or ask GitHub Copilot for a connect link; it is private and valid for ten minutes), then describe the post in plain language. GitHub Copilot reads the Bluesky rules, drafts within them, shows the plan and books on your yes. Bluesky is coming next; until the badge changes, the booking is refused with a plain message.
What can GitHub Copilot post to Bluesky through ClipSpeed?
Post 300-character text, images and short video to Bluesky. Bluesky takes text, image and video posts. Text is limited to 300 characters.
Which Bluesky settings can GitHub Copilot 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 GitHub Copilot sets the matching field before it books.
Do I need a Bluesky API key or developer account?
No. You connect Bluesky to ClipSpeed once through Bluesky's own sign-in, and GitHub Copilot talks to ClipSpeed over OAuth. No Bluesky developer key, bearer token or password is pasted anywhere.
How many Bluesky posts a day can GitHub Copilot schedule?
Planned: Text and image posts on Bluesky are at least 30 minutes apart, up to 10 a day. Video on Bluesky is at least 4 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 GitHub Copilot post to Bluesky from a script or a cron job?
Yes. GitHub Copilot'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 Bluesky from GitHub Copilot different from Cursor?
The booking is identical: the same rules, the same calendar, the same refusals. What differs is where you work. GitHub Copilot: vs code agent mode, jetbrains, the copilot cli. Cursor: cursor editor, standard mcp route, not yet verified by us.
