  • Chat app
  • Hosted MCP

Set up Capgo in ChatGPT

Three steps or less. Copy each block as is.

  1. Step 1

    Turn on developer mode

    In ChatGPT settings, open Apps, then Advanced settings, and turn on developer mode. In a workspace, an admin may need to allow it first.

  2. Step 2

    Create the Capgo app

    Create a new app or connector, name it Capgo, and paste this URL as the MCP server URL.

    MCP server URL
    $ https://api.capgo.app/mcp

  3. Step 3

    Sign in to Capgo

    Choose OAuth and sign in when the Capgo consent page opens. No API key needed. Then pick Capgo in a chat to use its tools.

What you can ask ChatGPT

Copy a prompt and paste it into ChatGPT. Replace the app ID and versions with yours.

  • Build

    “What is the status of my last iOS build on Capgo?”

  • Build

    “Why did my last Android build fail? Show me the logs.”

  • Update

    “Set bundle 2.3.1 on the production channel of com.example.app.”

  • Update

    “Pause the rollout on the production channel.”

  • Rollback

    “Roll back the production channel to the previous bundle.”

  • Observe

    “Show update stats for v2.3.0 over the last 7 days.”

  • Observe

    “Which devices are still on bundle 1.4.2?”

  • Observe

    “Compare update health between the last two bundles on production.”

ChatGPT notes and limits

  • ChatGPT runs in the cloud and cannot read your project. Bundle uploads and build requests need the Capgo CLI or an agent that runs local commands, such as Codex.
  • OpenAI lists custom MCP apps for Business, Enterprise, and Edu workspaces on ChatGPT web. Check your plan in the OpenAI help center.
  • Capgo marks tools that delete or overwrite data as destructive, so ChatGPT asks before it runs them.

FAQ

Capgo and ChatGPT: common questions

Can ChatGPT build my iOS app without a Mac?

ChatGPT can check build status, read build logs, and cancel builds through the hosted MCP. Starting a build needs your project files, so run the Capgo CLI or use an agent that runs local commands, such as Claude Code or Codex.

Native build docs

Do I need a Capgo API key for ChatGPT?

No API key needed for the hosted MCP. ChatGPT opens the Capgo sign-in page and you pick which organizations it can access.

Hosted MCP server docs

Can ChatGPT roll back a bad update?

Yes. Ask ChatGPT to point the channel back to the previous bundle. Devices switch on their next update check. The Capgo updater also rolls back on its own when a new bundle fails to start.

Live update docs

Are live updates allowed on the App Store and Google Play?

Yes, for the web layer: JavaScript, HTML, CSS, and assets. Native code, new permissions, and new plugins still need a store release, which Capgo Build can make for you.

What does it cost to use Capgo from ChatGPT?

The MCP servers, skills, and CLI are free to use. You need a Capgo plan, and every plan starts with a 14-day free trial with no credit card. Builds, live updates, and Observe are in every plan.
