Connections use OAuth 2.1 with PKCE and dynamic client registration, or bearer tokens limited to the mcp:use ability that you can revoke from the dashboard. Every media URL is fetched through an SSRF guard that blocks private networks and re-checks redirects. Uploaded files never travel as public URLs. Requests are rate limited per user, and the consent screen shows exactly where an OAuth token will be delivered.

Make and post reels from Claude, ChatGPT, Cursor and Codex

AI Video MCP Server

Shortzly is a remote MCP server for short-form video. Connect it to Claude, ChatGPT, Claude Code, Codex, Cursor or Windsurf, describe the reel you want, and your assistant writes the script, has Shortzly render it with a neural voiceover, stock visuals and animated captions, then publishes it to TikTok, YouTube Shorts and Instagram Reels. One URL, OAuth sign-in, no SDK to install.

How It Works

Three Steps From Chat to Published Reel

Connect the server

Paste https://shortzly.com/mcp into your assistant's connector settings, or run one command in Claude Code or Codex. Sign in once with OAuth or a dashboard token.

Describe the reel

Tell your assistant what you want. It writes every line of the script, picks stock media or your own uploads, and calls create_reel with a structured plan.

Render and publish

Shortzly renders the vertical video with voiceover, visuals and captions. Your assistant polls the job, upgrades it to HD and posts it to your connected accounts.

Why Shortzly

Why Developers Connect Shortzly

Your Model Writes, Shortzly Renders

The assistant you already pay for writes the hook, the script and the shot list. Shortzly does the part a chat model cannot: neural voiceover, stock footage, Ken Burns motion, word-level captions and a 1080x1920 MP4. You are never billed twice for the same intelligence.

Works With Every MCP Client

Claude Desktop and claude.ai, ChatGPT connectors, Claude Code, Codex, Cursor, Windsurf, VS Code and any other client that speaks the Model Context Protocol. One HTTPS endpoint, OAuth 2.1 with PKCE or a scoped bearer token, no SDK and no webhook server on your side.

Publish Without Leaving the Chat

The same connection lists your linked TikTok, YouTube, Instagram, Facebook and LinkedIn accounts, publishes the finished clip or schedules it for later, and reports back the live URL. Describe, approve, done.

Features

Everything Your Agent Needs to Ship Video

Remote MCP Over HTTPS

Stateless JSON-RPC at https://shortzly.com/mcp. Nothing to install, nothing to host, works from a laptop or a cloud agent.

OAuth 2.1 or Bearer Tokens

Dynamic client registration with PKCE for Claude and ChatGPT, or mint a scoped shz_ token in the dashboard for CLI and IDE clients. Revoke either at any time.

14 Typed Tools

Discover capabilities and quota, upload media, create reels, track jobs, fetch clips, upgrade to HD and publish, each with a JSON schema your model can read.

Bring Your Own Media

Pass public image or video URLs, or upload files through presigned PUT URLs. Your product screenshots and footage, Shortzly's render pipeline.

Stock Search Included

Give a segment a search phrase instead of a file and Shortzly pulls matching Pexels and Pixabay footage with no LLM in the loop.

Zero-AI-Cost Renders

Supply your own voiceover audio and choose timed captions, and a render costs Shortzly no AI at all. TTS and Whisper alignment are opt-in per call.

Six Neural Voices on Demand

Turn on Shortzly's text-to-speech when you want it: Nova, Onyx, Shimmer, Echo, Fable and Alloy with loudness-normalized output.

Preview First, HD on Demand

Render a fast 720p preview for half a credit, review it, then call upgrade_clip_hd for the full 1080x1920 master.

Brand Templates

Reference a saved template and every reel inherits your caption style, watermark, intro and outro without restating them in the call.

One-Call Publishing

publish_clip posts to any mix of connected TikTok, YouTube Shorts, Instagram Reels, Facebook and LinkedIn accounts, now or at a scheduled time.

Idempotent, Resumable Jobs

Repeat-safe idempotency keys, job polling with retry hints, cancellation and a full job list so an agent can recover after a restart.

Same Quota as the Dashboard

Reels created over MCP count against your normal monthly allowance, appear in your projects and clips, and never need a separate subscription.

Connect

Connect in 60 Seconds

Same URL everywhere. Claude and ChatGPT sign in with OAuth. Command-line and editor clients can use OAuth or a token from your dashboard.

Claude Desktop and claude.ai

1 Open Settings, then Connectors.
2 Choose Add custom connector and paste the server URL.
3 Approve the Shortzly sign-in screen. Claude registers itself with OAuth, no token to copy.

Server URL

https://shortzly.com/mcp

ChatGPT connectors

1 Open Settings, then Connectors, and turn on Developer mode.
2 Click Create, name it Shortzly and paste the server URL.
3 Sign in when ChatGPT asks. Enable the connector in a chat and ask for a reel.

Server URL

https://shortzly.com/mcp

Claude Code

1 Add the server with one command in your terminal.
2 Type /mcp inside Claude Code and pick Shortzly to sign in through the browser.
3 Prefer a token? Create one under Settings, API tokens and pass it as a header instead.

Terminal

claude mcp add --transport http shortzly https://shortzly.com/mcp

# or with a dashboard token
claude mcp add --transport http shortzly https://shortzly.com/mcp \
  --header "Authorization: Bearer <id>|shz_..."

OpenAI Codex CLI

1 Register the server, then log in once.
2 Codex stores the OAuth grant and refreshes it for you.
3 For CI, set bearer_token_env_var in ~/.codex/config.toml and export a dashboard token.

Terminal

codex mcp add shortzly --url https://shortzly.com/mcp
codex mcp login shortzly

Cursor, Windsurf and VS Code

1 Create a token under Settings, API tokens in your Shortzly dashboard.
2 Add the server to mcp.json (VS Code uses a "servers" key with "type": "http").
3 Reload the editor. The 14 Shortzly tools appear in the agent's tool list.

mcp.json

{
  "mcpServers": {
    "shortzly": {
      "url": "https://shortzly.com/mcp",
      "headers": {
        "Authorization": "Bearer <id>|shz_..."
      }
    }
  }
}

Tokens and connected apps live under Settings, API tokens and MCP in your dashboard. Revoke either at any time.

Cost model

You Bring the Words. Shortzly Brings the Render.

A reel counts against your monthly quota the same way as in the dashboard: half a credit for a preview, one credit for HD. Everything Shortzly's own AI does on top is opt-in per call.

Part of the reel	You supply it	Or Shortzly does it
Script and shot list	Your model writes it, always	Never runs its script AI on this path
Images and video	Public URL or uploaded asset, free	Stock search on Pexels and Pixabay, free, no LLM
Voiceover	Upload your own audio, free	Neural text-to-speech, six voices, paid AI
Captions	Timed from the script, free	Whisper word alignment, paid AI
B-roll	Off by default, free	Stock B-roll with an LLM cue pass, opt-in

Upload a voiceover and choose timed captions and the render uses none of Shortzly's AI at all. Your model's cost stays with your model.

Security

Built for Agents, Locked Down for Humans

OAuth 2.1 with PKCE

Dynamic client registration for Claude and ChatGPT, discovery documents at the standard well-known paths, and a consent screen that shows exactly which host will receive the token.

Scoped, revocable tokens

Dashboard tokens carry only the mcp:use ability, are shown once, and can be revoked individually. Connected OAuth apps are listed and removable in the same place.

SSRF-guarded media fetches

Every media URL is https only, resolved against private, loopback, link-local and cloud metadata ranges, re-checked on every redirect and capped in size. Uploads never travel as public URLs.

Rate limits and idempotency

120 requests per minute per user, 10 registrations per minute per IP, and repeat-safe idempotency keys so a retried create_reel never renders twice.
