Connection key

Make videos in Kiro

Connect Idea to Motion to Kiro and you can ask for a video the same way you ask for anything else. Kiro 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 launches MCP servers as local processes rather than calling them over HTTP, so the mcp-remote bridge carries your key to the server for you.

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

Add it to Kiro

.kiro/settings/mcp.json (per project) or ~/.kiro/settings/mcp.json (user)

{
  "mcpServers": {
    "ideatomotion": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://api.ideatomotion.com/mcp",
        "--header",
        "Authorization:Bearer vai_YOUR_KEY"
      ],
      "disabled": false,
      "autoApprove": []
    }
  }
}

Generate a key above to replace vai_YOUR_KEY.

Open it from the MCP panel: Kiro → MCP Servers → Edit config, or edit the file directly.
Kiro spawns stdio processes, so the mcp-remote bridge carries your key over HTTP.
The header has no space after the colon — mcp-remote splits arguments on spaces.

Where the config lives

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

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

Config files: .kiro/settings/mcp.json (per project) or ~/.kiro/settings/mcp.json (user)
Format: JSON
Root key: mcpServers
Endpoint field: Passed to mcp-remote as an argument
Your key: Passed to mcp-remote as a --header argument, so it sits in the file
Fastest route: Hand-edit the file below, or let the agent write it for you
After saving: Reload or restart Kiro — 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 Kiro can actually do

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

Ask for a video from Kiro's agent panel the same way you ask for a change to the code — the tool calls run beside your editor, and you approve the plan there.

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 into the agent panel, in the same thread you use for code.

“Make a 30-second vertical explainer about the feature I just finished.”

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 Kiro

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

You cannot find the config, or an edit does not take

Kiro → MCP Servers → Edit config opens the right file; editing it directly works too. Kiro spawns stdio processes rather than calling HTTP, so the entry runs the mcp-remote bridge locally and carries your key over it. The entry also ships a disabled flag — if the panel has switched the server off, that is where it shows, and a disabled server looks identical to one that failed to load.

Kiro starts fine and the server never appears

Check the names in .kiro/settings/mcp.json. The entry belongs under mcpServers, and the URL is an ARGUMENT to mcp-remote rather than a field of its own, so its position in the args array matters. These differ between clients — some read mcpServers, some servers, some context_servers — and a wrong one is not an error: the file parses, Kiro 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 Kiro. 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: .kiro/settings/mcp.json (per project) and ~/.kiro/settings/mcp.json (user). 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 Kiro is ignoring. Put it in the user-level file if you want it everywhere, and reload Kiro either way.

The bridge fails to start, or the first launch takes a while

Kiro launches MCP servers as local processes, so this entry runs npx -y mcp-remote on your machine and needs Node on the PATH Kiro inherits — which is not always the PATH your shell has. The -y flag fetches the bridge on first use, so the first launch is slower than every later one. Note that the header argument has no space after the colon, because mcp-remote splits its arguments on spaces.

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 Kiro. Silent motion graphics need no voice key at all, so "make it a silent motion graphic instead" is a valid way past this.
