37Studio MCP server

37Studio makes videos for a business and runs its social accounts, from one app on your own computer. Add a brand from its website and it builds a brand library and a knowledge base. Brief a video and Claude Code, the editor agent, builds it as a HyperFrames composition in that brand, checks its own frames and renders it on your machine. Publish it to the brand's accounts with a caption written for each platform, now, on a schedule or on Autopilot. Messages and comments land in one inbox with replies drafted from the knowledge base.

You bring your own keys (a Claude plan or an Anthropic API key; optionally OpenAI, xAI, OpenRouter, Gemini, fal.ai or ElevenLabs) and pay the providers directly. It is free and open source under the MIT License, made by Shaitrish in Dhaka.

Install

Desktop app (Windows 10/11 and Linux). Download it from studio.shaitrish.com/desktop:

• Windows: open the installer. It needs no admin rights and adds 37Studio to the Start menu and desktop. Windows may say it protected your PC, because the app isn't signed yet: More info → Run anyway.
• Ubuntu 24.04+ / Debian 13+: sudo apt install ./37studio_*_amd64.deb (it brings ffmpeg and Python).

Then install the tools the agent uses. Overview → Finish setup in the app lists anything missing:

winget install Git.Git Gyan.FFmpeg OpenJS.NodeJS.LTS Python.Python.3.13   # Windows only
npm install -g @anthropic-ai/claude-code    # Node.js 22+; on Linux with sudo

docs/desktop.md covers other Linux, the .zip, building it yourself and troubleshooting.

Docker (macOS, or a server). Every tool comes bundled. On your computer, install Docker Desktop, unzip 37studio.zip and double-click start.bat, start.command or start.sh. For a team, or replies and Autopilot around the clock, run it on a Linux server with HTTPS and a password. docs/docker.md has both, plus building from source and every setting.

One-Click Deploy

First steps

1. Add your Claude key in Settings → AI services (an Anthropic API key, or a Claude plan token from claude setup-token).
2. Add a brand from its website or a folder. In 5 to 10 minutes its library, design system and knowledge base are ready.
3. Make a video. New video asks what to make; the agent builds it while you watch, and takes changes in plain words.
4. Connect accounts on the brand's Social tab (how), then Publish now, on a schedule, or with Autopilot.

The user guide, also inside the app as Guide, covers every screen.

What it does

• Brand library from a website or folder. Paste a URL, or pick the brand's own project folder, and get its logos, people, photos, fonts and exact colours sorted and captioned, plus a design system (design.md) and a knowledge base (knowledge.md).
• An editor agent. Claude Opus 5.5 builds each video as an animated HyperFrames composition, checks its own frames and takes changes in plain words. Edit by hand on a real timeline when you want to.
• Many kinds of output. Hook reels, captioned clips, motion-graphics explainers, podcast clips, promo ads, square and portrait posts, and thumbnails. Save any finished video as a template for the next one.
• Long recordings into many videos. A 2-hour class becomes ten reels. Transcription runs locally with faster-whisper: free, private, about 100 languages. YouTube and Google Drive links import directly.
• Generated media. Gemini images; video clips from Gemini or, through fal.ai, Seedance, Kling, Veo, Wan and others; ElevenLabs voiceover, sound effects and music. Each brand can keep its own voices, cloned from a short recording of the founder or presenter, with a default per language; ask the agent for a voice by name, or to switch a finished video to it. The agent asks before media on one project costs more than the limit in Settings → Spending, and keeps a person or product consistent by reusing one reference image across shots. The agent uses them only when the footage and brand library can't do the job, and says what it made.
• Publishing and Autopilot. Post to any mix of a brand's accounts on nine platforms now or on a schedule, or let a content plan make a fresh video before every slot and wait for one-click approval.
• One inbox. Messenger, Instagram and WhatsApp messages and Facebook and Instagram comments, with replies drafted in the customer's language, following the brand's own rules. Off, drafts to approve, or fully automatic, per brand.
• Performance. Views, how much of each video people watched, likes, comments, shares, saves and engagement for every video on the brand's Facebook, Instagram, YouTube and TikTok, best and worst on top. The editor agent reads the same numbers before it plans the next video.
• Assistant and MCP. Run everything by chatting with the Assistant in the sidebar, or from your own AI agent (Claude Code, Claude Desktop, Cursor) through 37Studio's MCP server: brands, campaigns, videos, publishing, Autopilot, settings and connections.
• Real costs. Every project, campaign and brand shows its AI spend in your currency. No markup: you pay the AI providers directly.

Platforms

Platform	Publishes	Inbox	You connect with
Facebook Pages	Reels and Page videos	Messenger, comments	Facebook Login through your own Meta app
Instagram (Business or Creator)	Reels	Messages, comments	The same sign-in as Facebook
YouTube	Videos		Your own Google OAuth client
TikTok	Videos, or to the creator's drafts		Your own TikTok app
LinkedIn	Videos to your profile; company Pages with LinkedIn's approval		Your own LinkedIn app
X	Video posts		Your own X app
Pinterest	Video Pins, on the boards you pick		Your own Pinterest app
Bluesky	Video posts		Handle and an app password
Mastodon	Video posts		Server URL and an access token
WhatsApp		Messages	A WhatsApp Business API number and a Cloudflare Tunnel to your copy (or your own relay)

Not possible: Threads (its API only takes a video from a public URL, which a local-first app doesn't have), Facebook Groups and personal profiles (Meta removed it), Reddit and Snapchat (no usable public video-posting API). Setup for each one: docs/platforms.md.

How it works

Browser ──► 37studio (Go, one binary) ──► SQLite + data/ (brands, projects, encrypted tokens and keys)
             ├─ claude -p, the editor agent ──► ffmpeg · npx hyperframes · 37studio gen / transcribe / clip
             ├─ hyperframes render (Chrome + ffmpeg) ──► out/*.mp4, *.png
             ├─ post queue ──► Facebook · Instagram · YouTube · TikTok · LinkedIn · X · Pinterest · Bluesky · Mastodon
             └─ inbox loop ──► Messenger, Instagram (Graph API) · WhatsApp (webhook through your tunnel, or your own relay)

Claude Code does the editing, HyperFrames renders, Go serves and React is the UI. Any MCP client (Claude Code, Claude Desktop, Cursor) can run the whole app through its MCP server at http://localhost:8080/mcp: claude mcp add --transport http 37studio http://localhost:8080/mcp. docs/architecture.md has the job flow, the agent harness, a code map and the release process.

What leaves my computer? Calls to the AI providers you set up, uploads to the platforms you connect, and the update check (GitHub Releases). Nothing is sent to Shaitrish. Questions and problems: the guide's Troubleshooting, or open an issue.
