Connect rompix to ChatGPT & Claude

rompix runs a small MCP server, so an AI client like ChatGPT or Claude can create a keyframe in your rompix account and start its first image render — then hand you back a link to open it on the canvas and keep iterating. Connecting takes a couple of minutes and uses OAuth (you sign in with Google and approve a consent screen). Generating a frame spends your rompix credits.

What you'll need

Connect from ChatGPT (Developer Mode)

ChatGPT adds custom MCP connectors through Developer Mode. Turn it on once, then add rompix as a connector.

  1. Open Settings → Apps. On the web app, open Settings and go to Apps (App Preferences). This is where connectors live.
    ChatGPT Settings, Apps tab: Permissions, Enabled apps, and an Advanced settings row with a Create app button.
  2. Enable Developer mode. Open Advanced settings and turn Developer mode on. It warns about elevated risk — that's expected for custom connectors; accept it. You can leave “Enforce CSP in developer mode” off.
    ChatGPT Advanced settings panel with a Developer mode toggle marked Elevated risk, and an Enforce CSP in developer mode toggle.
  3. Create the connector. Go back to Apps and click Create app (Create connector).
  4. Fill in the form. Set Name to rompix, leave the connection on Server URL and enter https://app.rompix.com/api/mcp, and set Authentication to OAuth. (Not “No authentication” and not an API key — rompix only accepts OAuth.) Acknowledge the custom-connector risk notice (“I understand and want to continue”), then click Create.
    ChatGPT’s New App form: Name set to rompix, connection on Server URL with https://app.rompix.com/api/mcp, Authentication set to OAuth, the “I understand and want to continue” risk box checked, and a Create button.
  5. Authorize. The first time you use the connector, ChatGPT runs the OAuth flow: it sends you to rompix, you sign in with Google, then approve the “Authorize access” consent screen (it shows the connector’s name and warns it can create keyframes and spend your credits). Click Allow.
    The rompix “Authorize access” consent screen: ChatGPT (chatgpt.com) is asking to connect and create frames on your behalf, with Deny and Allow buttons.
  6. Use it. Ask ChatGPT to create a frame (for example: “create a frame: a neon-lit alley at night”). The create_frame tool runs and returns a link like https://app.rompix.com/?keyframe=… — open it to see the frame on the canvas.

Connect from claude.ai

The same server works as a custom connector in claude.ai. The authorization step is identical (Google sign-in → the same rompix consent screen).

  1. Add a custom connector. In claude.ai, open Settings → Connectors and choose Add custom connector.
    claude.ai’s “Add custom connector” dialog with the name set to rompix and the URL set to https://app.rompix.com/api/mcp, plus Cancel and Add buttons.
  2. Enter the URL. Set the name to rompix and the URL to https://app.rompix.com/api/mcp, then click Add.
  3. Authorize. Sign in with Google and approve the “Authorize access” consent screen, same as above.
  4. Use it. Ask Claude to create a frame; create_frame returns the ?keyframe=… link to open it on the canvas.

The tool — create_frame

rompix exposes exactly one tool. It creates a new keyframe, starts its first image render, and returns a link to open the frame.

Inputs
FieldRequiredDefaultNotes
description Yes — 1–2000 characters. Becomes the frame’s name (first 60 characters) and the prompt for the first image.
aspect No 9:16 One of 9:16, 16:9, 1:1. Fixed for the life of the frame.
resolution No 1080p One of 720p, 1080p.

Returns a link to the new frame on your canvas: https://app.rompix.com/?keyframe=<id>.

Troubleshooting

Stuck at sign-in, or you see access_denied
The Google account you signed in with doesn’t have a verified email address. Sign in with a Google account whose email is verified, then try again.
The connector won’t add, or you get an OAuth discovery error
Make sure the URL is exactly https://app.rompix.com/api/mcp — no trailing slash and no extra path. rompix publishes the OAuth discovery documents the client looks for under /.well-known/, so the bare /api/mcp URL is all you enter.
You get a 401 / “unauthorized”
rompix accepts OAuth tokens only — it does not take a static API key or personal access token. Make sure Authentication is set to OAuth and complete the sign-in + consent flow.
It asks you to approve a consent screen every time you authorize
That’s intentional. The screen shows the connecting app’s name and where it will send you back, so you can confirm it’s the app you expect before granting access.
