Post to Mastodon from Meta Muse AI
Meta Muse AI can post to Mastodon on Mastodon through ClipSpeed. Add the ClipSpeed connector, sign in, and then ask Meta Muse AI to post to Mastodon, pick the time, and apply Mastodon's settings, without leaving the Muse app, muse.ai and WhatsApp. Mastodon is on the roadmap on ClipSpeed's rail; this page describes how it works and says so.
Keep a human in the loop: Meta Muse AI shows the plan and asks before anything is public. Posting today: YouTube, TikTok, Instagram, X (Twitter) and LinkedIn.

How to post Mastodon from Meta Muse AI
Muse builds the connector from your description. Paste the message, approve the sign-in link it sends back, and it saves the connector and a skill. Connect Mastodon in ClipSpeed, then describe the post. Setup takes about a minute.
# One-time setup: new message to Muse
Add my ClipSpeed connector: https://api.clipspeed.ai/mcp
- It is a standard MCP server over HTTP with OAuth. Send me the sign-in link and I will approve it.
- Save a skill so every request about clips, posts or scheduling goes through the ClipSpeed tools.
Once connected, list my connected channels.
# Then ask Meta Muse AI:
> Post the announcement to Mastodon at 9am
Meta Muse AI: Preview — nothing booked yet. Mastodon — text under 500. Book it?ClipSpeed has not yet run an end-to-end check inside Muse, and ClipSpeed is not listed in Muse's connector directory. The route above is Muse's custom-connector flow with a standard MCP server.
- Paste the setup message into a new Muse conversation on the web, in the app or on WhatsApp.
- If Muse asks, confirm the server is a URL over HTTP and uses OAuth, not an API key.
- Open the sign-in link Muse sends back and approve it with your ClipSpeed account.
- Connect Mastodon in the ClipSpeed app, or ask Meta Muse AI for a connect link: it is private, valid for ten minutes, and Mastodon signs you in itself.
What can Meta Muse AI do on Mastodon?
On Mastodon, Meta Muse AI can post 500-character text, images and video to a Mastodon account on any server. Every booking runs through the same rules as the ClipSpeed app.
Text, Image and Video posts
Mastodon takes text, image and video through ClipSpeed. Video: MP4 or WebM. Image: JPG, PNG or GIF; up to four per post on Mastodon.
500 characters, checked at booking
Mastodon'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 Meta Muse AI books it, or you are told why not and offered the next open slot. A booked Mastodon post is never moved behind your back.
Preview before anything posts
preview: true runs the whole booking and writes nothing. Meta Muse AI 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 Mastodon. No download, no re-upload.
Pacing and numbers
Planned: Text posts on Mastodon are at least 30 minutes apart, up to 10 a day. Video on Mastodon is at least 4 hours apart, up to 4 a day under your plan. After a post goes out, Meta Muse AI can read back views and engagement where Mastodon provides them.
How does Meta Muse AI post to Mastodon through ClipSpeed?
You describe what you want in plain language and Meta Muse AI makes the ClipSpeed calls. A typical conversation has three beats.
Find your Mastodon channel
Ask Meta Muse AI whether Mastodon is connected. It calls list_channels and reads platform_settings, so it also knows what Mastodon accepts and the limits before you write a word.
Compose within the rules
Describe the post. Meta Muse AI drafts within Mastodon'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.
Mastodon settings reference
These are the schedule_post fields that apply to Mastodon. Mention any of them in plain language and Meta Muse AI sets them; the server checks them at booking. Fields marked planned land with the Mastodon release.

Mastodon limits and gotchas to know
Mastodon enforces a few rules that Meta Muse AI and ClipSpeed respect automatically, but knowing them helps you phrase requests.
- 500 characters is the default limit, with every link counted as 23. Some servers allow more; ClipSpeed will use your server's limit at booking.
- Your account lives on one server; you connect that server, not mastodon.social in general.
- Mastodon is on ClipSpeed's roadmap, not the next rail. Bookings are refused plainly until it posts.
- Content warnings and alt text are planned fields.
- Planned pacing: ten text posts a day 30 minutes apart, video four hours apart.
| Rule | Mastodon |
|---|---|
| Accepts | Text, Image, Video |
| Text limit | 500 characters; every link counts as 23 (500 is the default; your server may allow more) |
| Title | No title field |
| Links in the caption | Kept; every link counts as 23 characters |
| Pacing | Planned: Text posts on Mastodon are at least 30 minutes apart, up to 10 a day. Video on Mastodon is at least 4 hours apart, up to 4 a day under your plan. |
| Formats | Image: JPG, PNG or GIF; up to four per post on Mastodon. Video: MP4 or WebM. Aspect: any |
| Status | On the roadmap; described here, not yet bookable |
What Postiz-style schedulers cannot do
Cut the clips first
Meta Muse AI 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. Meta Muse AI picks by score, writes the caption from the transcript, and books the clips on Mastodon. 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. Meta Muse AI 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 Mastodon. 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: Meta Muse AI 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 Meta Muse AI?
Meta Muse AI is Meta's personal agent that takes actions through connectors it builds itself when you describe a server to it. It runs on a dedicated secure VM, lives in the Muse app, at muse.ai and inside WhatsApp, and a separate agent checks outbound actions. With the ClipSpeed server described to it, Muse can clip videos, generate media and schedule posts.
How ClipSpeed works with Meta Muse AI
- Muse builds an MCP client to the ClipSpeed server

Mastodon and Meta Muse AI: frequently asked questions
How do I post to Mastodon from Meta Muse AI?
Paste the setup message into a new Muse conversation on the web, in the app or on WhatsApp. If Muse asks, confirm the server is a URL over HTTP and uses OAuth, not an API key. Connect Mastodon in ClipSpeed (or ask Meta Muse AI for a connect link; it is private and valid for ten minutes), then describe the post in plain language. Meta Muse AI reads the Mastodon rules, drafts within them, shows the plan and books on your yes. Mastodon is on the roadmap; until the badge changes, the booking is refused with a plain message.
What can Meta Muse AI post to Mastodon through ClipSpeed?
Post 500-character text, images and video to a Mastodon account on any server. Mastodon takes text, image and video posts. Text is limited to 500 characters, with every link counted as 23.
Which Mastodon settings can Meta Muse AI control?
The fields in the settings reference above: text, visibility, media_kind, clip_id or media_url, scheduled_at, preview. Mention any of them in plain language ("unlisted", "tomorrow at 9", "preview first") and Meta Muse AI sets the matching field before it books.
Do I need a Mastodon API key or developer account?
No. You connect Mastodon to ClipSpeed once through Mastodon's own sign-in, and Meta Muse AI talks to ClipSpeed over OAuth. No Mastodon developer key, bearer token or password is pasted anywhere.
How many Mastodon posts a day can Meta Muse AI schedule?
Planned: Text posts on Mastodon are at least 30 minutes apart, up to 10 a day. Video on Mastodon 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 posts go out to Mastodon while I am away?
Yes. Once booked, ClipSpeed publishes at the scheduled minute whether or not Meta Muse AI is open. For unattended runs that decide what to post, use a headless agent such as Claude Code or Codex with the same account.
Is posting to Mastodon from Meta Muse AI different from Meta AI?
The booking is identical: the same rules, the same calendar, the same refusals. What differs is where you work. Meta Muse AI: muse app (ios, android), muse.ai, whatsapp. Meta AI: facebook, instagram, messenger, whatsapp, answers questions; no connectors.
