Motion Text MCP server

Turn words, images, and audio into an animated video with MP4 export.

Motion Text is a kinetic story studio. This repository is the front door for its hosted MCP server — the server itself is a remote service, so there is nothing here to install or run.

• Privacy: https://motiontext.video/privacy

• Registry: video.motiontext/motion-text

Two endpoints

The server is hosted and speaks streamable HTTP. There is no npm package and no local process.

Use /mcp/studio. It is the URL you want in almost every case — it authenticates you and unlocks the full toolset: scenes, narration, stock photos, music, brand and logo, render and export.

/mcp exists so that a client with no account can connect and evaluate the server immediately. It answers anonymously and exposes three tools (create_story_draft, list_visual_presets, get_spec), enough to build a draft and hand it off to the editor.

The distinction matters because of when each endpoint challenges. /mcp only sends a WWW-Authenticate challenge if you present a token that turns out to be invalid; arriving with no token connects cleanly. /mcp/studio challenges immediately, which is what makes a client start the OAuth flow on its own.

Some clients — ChatGPT is the one that bites — begin sign-in only in response to a challenge. Point those at /mcp/studio or they will connect to /mcp, never prompt, and appear to be a broken server with three tools.

Setup

Claude Code

claude mcp add --transport http motion-text https://motiontext.video/mcp/studio

Then run /mcp inside Claude Code to complete the OAuth sign-in.

Claude Desktop / claude.ai

Settings → Connectors → Add custom connector, and give it https://motiontext.video/mcp/studio. Sign-in runs in the browser.

ChatGPT

Add it as a custom connector with https://motiontext.video/mcp/studio. Use that URL specifically — see the note above.

Generic client config

{
  "mcpServers": {
    "motion-text": {
      "type": "streamable-http",
      "url": "https://motiontext.video/mcp/studio"
    }
  }
}

Try it without an account

curl -sS -X POST https://motiontext.video/mcp \
  -H 'content-type: application/json' \
  -H 'accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

What you can build

Ask your agent for a video and it drafts one — you finish it in the editor at motiontext.video.

• Kinetic captions — lyrics or a script timed to audio, with per-line motion (beat, glitch, slam, karaoke, and others)

• Narrated picture stories — scenes with generated or stock imagery and text-to-speech narration

• Brand treatment — colors, typography, logo, and format presets

• Export — render to MP4

Call get_spec for the machine-readable capabilities, limits, and draft schema.
