Connection key

Make videos in Gemini CLI

Connect Idea to Motion to Gemini CLI and you can ask for a video the same way you ask for anything else. Gemini CLI writes the script, plans each scene and writes the animation code; we synthesize the voiceover, time it to the words, render the animation and hand back an MP4. It speaks Streamable HTTP directly, so connecting is one config entry carrying an API key in an Authorization header.

1Mint a connection key below.
2Add the config entry to your client and reload it.
3Connect a voice key, then ask for a video in chat.

Add it to Gemini CLI

~/.gemini/settings.json or .gemini/settings.json

{
  "mcpServers": {
    "ideatomotion": {
      "httpUrl": "https://api.ideatomotion.com/mcp",
      "headers": {
        "Authorization": "Bearer vai_YOUR_KEY"
      },
      "timeout": 30000
    }
  }
}

Generate a key above to replace vai_YOUR_KEY.

httpUrl selects Streamable HTTP; plain url would mean SSE.

Where the config lives

The exact names Gemini CLI reads, and what happens when one of them is wrong.

Gemini CLI reads its MCP servers from a JSON file — ~/.gemini/settings.json. It can live in either of two places, and the per-project one only applies inside that project. The entry goes under mcpServers, with the endpoint in httpUrl. Those names are not what every other client uses, and getting one wrong is not an error, it is silence: the file parses, Gemini CLI starts, and the server never appears.

Config files: ~/.gemini/settings.json or .gemini/settings.json
Format: JSON
Root key: mcpServers
Endpoint field: httpUrl
Your key: Written into the file as an Authorization header
Timeout: timeout is set to 30000, because a scene render holds a request open for tens of seconds
Fastest route: Hand-edit the file below, or let the agent write it for you
After saving: Reload or restart Gemini CLI — MCP config is read when the client starts

02Connect your voice

Narration is synthesized on your own ElevenLabs, Cartesia or Sarvam AI key. Silent motion graphics need none.

Your voice key

Idea to Motion generates the voiceover on your own text-to-speech account. Add an ElevenLabs, Cartesia or Sarvam AI key — it's stored encrypted and never shown again. Rendering is blocked until a key is connected.

What Gemini CLI can actually do

Where the line between your assistant and the platform falls, and why it falls there.

Ask for a video in a Gemini CLI session the same way you ask for a refactor — the tool calls run inline and you approve the plan without leaving the terminal.

It writes the content — a narrated script, a silent shot list, or a keep-and-drop cut plan for a video you upload — and hands it back for approval. Nothing is produced until you say yes.
It directs every scene, then writes a self-contained Remotion component for each one. Submitted code is validated and run in a sandbox before it is accepted, so a mistake comes back as a tool error it can fix rather than a broken video.
It renders stills of its own scenes on our servers and looks at them, which is why it can correct a card sitting across someone's face without you screenshotting anything.
We do the parts a language model should not be doing: voice synthesis, word-level timing, captions, music, assembly and the final render.
There is deliberately no export tool. Exporting spends money and picks a quality tier, so it stays a click you make on the platform — and a video you have already paid for re-exports for free.

A worked example

Type it at the prompt, in any directory — nothing about this needs a project.

“Make a 20-second silent motion graphic announcing our v2 release.”

What comes back

1It opens a picker: the looks play as short clips, the narrator voices have samples you can hear, and you choose. Clients that cannot draw a panel get the same list as text.
2It writes the script and shows it to you. Tell it what to change and it rewrites — the video does not start until you approve.
3It directs and writes each scene, checking stills as it goes. This is the long part, and it is mostly quiet: a scene submission legitimately holds its request open while the server renders.
4The finished video appears in your projects here. Watch it, ask for adjustments in the same conversation, then export it from the platform.

Troubleshooting Gemini CLI

The ways this goes wrong, and most of them go wrong silently.

It connects, then every call hangs or fails

httpUrl is what selects Streamable HTTP. A plain url in the same position means SSE, which this server does not serve — and the entry still parses, so the mistake surfaces as a transport that never completes rather than as a config error. Open Command Palette → Configure MCP Servers only after checking that field.

Gemini CLI starts fine and the server never appears

Check the names in ~/.gemini/settings.json. The entry belongs under mcpServers, and the endpoint goes in httpUrl. These differ between clients — some read mcpServers, some servers, some context_servers — and a wrong one is not an error: the file parses, Gemini CLI starts, and the server is simply never loaded. Copy the snippet in step 1 rather than adapting one from another client's documentation.

It says it cannot connect, or every tool call comes back 401

A key that is wrong, truncated or revoked gets a 401, and most clients report that as a failed connection rather than as an auth problem. Keys are shown once and stored hashed, so there is no way to read an old one back — generate a fresh one in step 1, then paste the new key over the old one in the config and reload Gemini CLI. Paste the whole vai_ string including the prefix; the old key can be revoked from the same panel.

You saved the config and nothing changed

This can live in two places: ~/.gemini/settings.json and .gemini/settings.json. A per-project file only applies while you are working in that project, so an entry in the wrong one reads exactly like a config Gemini CLI is ignoring. Put it in the user-level file if you want it everywhere, and reload Gemini CLI either way.

The tools work but it cannot produce the voiceover

Narration and transcription run on your own ElevenLabs, Cartesia or Sarvam AI key rather than ours, so a narrated or recorded video needs one connected — step 2 on this page, or the set_voice_key tool from inside Gemini CLI. Silent motion graphics need no voice key at all, so "make it a silent motion graphic instead" is a valid way past this.
