The steps,
one at a time.

  1. 1

    Open Plugins

    In ChatGPT, open Plugins, press + and choose Add custom MCP server.

  2. 2

    Paste the URL

    Name it Omnibo, add a short description and paste this URL.

    https://app.omnibo.ai/api/mcp
  3. 3

    Set up sign-in

    Configure auth with OAuth, so ChatGPT sends you to Omnibo to sign in.

  4. 4

    Confirm and create

    Confirm “I understand and want to continue”, then choose Create as a plugin.

  5. 5

    Sign in and ask

    Sign in with your Omnibo account, approve what the connection may do, then ask ChatGPT: “Generate a cinematic image of a lighthouse at dusk and show it to me.”

  • ChatGPT treats Omnibo as a custom MCP server: you add it yourself with the URL.
  • Whether you can add one depends on your ChatGPT account and workspace policies.

On Omnibo, video, audio, web search and the planner need Starter or higher.

Signing in

The server signs you in with OAuth: your client opens a browser, you sign in to your Omnibo account, and a consent screen lets you approve what the connection may do. Clients that accept a custom header can use an API key instead, from Settings → MCP & API keys.

What it costs

Everything runs on your Omnibo credits, at the same rates as the app. list_models shows each model’s rate and the plan it needs, and balance shows what is left. A generation returns a job, which job_status and wait_for_job follow. Nothing here publishes anywhere.

The tools
you can call.

Names as the server gives them. What your connection can call depends on what you approved when you signed in.
