Muse4AI

Let your AI agent make the pictures and the videos.

Muse4AI runs on your own Windows PC and hands your Muse session to ChatGPT, Claude, Cursor, Codex, n8n or anything else that speaks REST, MCP or OAuth — with no cloud middleman and no per-seat fee.

Nothing is relayed through a server we run. The app talks to Muse from your machine, with your session, and keeps every result, key and token in %APPDATA%\MuseStudio on that same machine.

What you can ask an agent to do

🎬 Generate video & images One call, text-only or with reference photos. Repeat a prompt, pick the account, watch it appear in the in-app queue.	💬 Chat that remembers Ask questions or iterate on an idea. The conversation id comes back, so the agent can keep the thread going and attach files.
⏱ Extend a finished video Keep a clip rolling, up to 6 steps and about 60 seconds per chain, in the same conversation it was born in.	🛠 Edit a video by describing it Attach an MP4 and say what to change in words — no timeline, no rendering settings.
🔑 Two ways to connect An API key you paste once, or real OAuth: the agent asks, and you approve with the 6-digit code the app shows on screen.	📚 Built-in guide Every screen has a bilingual guide (English / Vietnamese) with real screenshots, plus a Skill your agent can read.

See it in action

Studio — write the prompt, attach references, run.	Queue — live status, thumbnails, quick preview.
Library — everything you made, searchable.	API & agent — connect an agent in one paste.

Quick start

1. Install (easiest)

Grab the installer from the download page, run it, then add your Muse account in Accounts. Windows will warn that the file is unsigned — choose More info → Run anyway.

2. Run from source

Needs Node.js 22+.

cd desktop
npm install
npm run build
npm start

The app opens on your desktop and serves its API on http://127.0.0.1:47821.

Connect an agent

Open Settings → API & agent in the app. It shows a ready-made snippet with your key already filled in — paste it into your agent's config.

OAuth (no key to copy)

The app is a real OAuth authorization server: it publishes /.well-known/oauth-authorization-server, registers clients dynamically and signs its own tokens. Point the agent at the MCP endpoint and let it redirect:

{
  "mcpServers": {
    "muse4ai": { "url": "http://127.0.0.1:47821/mcp" }
  }
}

The app then shows a 6-digit code. Type it into the consent page and the token is issued. Anyone who only knows the link cannot grant themselves access. Revoke any app later under Settings → API & agent → Connected apps.

API key

Create a key in the same screen (msk_…), then send it as a bearer token:

curl -X POST http://127.0.0.1:47821/v1/jobs \
  -H "Authorization: Bearer msk_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"kind":"video","prompt":"a coffee cup on an oak desk, warm morning light"}'

Keys are scoped, rate-limited and individually revocable.

What the agent gets

REST	MCP tool
POST /v1/jobs — image / video	muse_generate
POST /v1/jobs with kind:"chat"	muse_chat
GET /v1/jobs · GET /v1/jobs/{id}	muse_list_jobs · muse_get_job
POST /v1/jobs/{id}/cancel	muse_cancel_job
POST /v1/assets/{id}/extend · POST /v1/conversations/{id}/extend	muse_extend_video · muse_get_extend
GET /v1/status · GET /v1/health	muse_status

Full machine-readable contract: GET /v1/openapi.json. For agents that prefer Markdown: llms.txt.

Honest notes

• Unofficial. Muse4AI is an independent project. It is not affiliated with, endorsed or sponsored by Meta Platforms, Inc. "Meta" and "Muse" are trademarks of their owners.
• You own the risk. The app automates your Muse session. Automating a web app can break when the site changes, and may not fit Meta's terms of service — read them before you rely on it.
• Windows first. macOS and Linux builds are not packaged or tested yet; the core code does not depend on Windows, so porting is on the roadmap.
• No cloud account. There is no sign-up, no telemetry server and no subscription.
