Apper for ChatGPT

Build Apper apps inside ChatGPT​

Connect Apper to ChatGPT, describe the app you want in plain English, and keep building it directly from your ChatGPT conversation.

Apper can create your app, show you a working preview, make changes whenever you ask, and connect the app to a real database when you are ready.

Connect Apper to ChatGPT​

MCP server URLhttps://mcp.apper.io/v1.1/connect
  • Open ChatGPT → Settings → Apps.
  • Enable Developer Mode if required for your account or workspace.
  • Add Apper as a custom MCP app using the server URL above.
  • Connect your Apper account and complete the sign-in process.
  • Start a new chat and enable Apper for the conversation.
  • Tell ChatGPT what you want to build.
info

Access to custom MCP apps and their available actions depends on your ChatGPT plan and workspace settings.

Start building​

You don't need to know any MCP commands or tool names. Just describe what you want.

For example:

  • "Build a CRM for managing leads, contacts, and deals."
  • "Create a to-do app with categories and due dates."
  • "Show me a preview of my app."
  • "Add a dark mode option."
  • "Add a dashboard showing monthly sales."
  • "Connect this app to a real database."
  • "Show me my Apper apps."

ChatGPT automatically selects the appropriate Apper tools based on your request.

Typical flow​

  • Describe your app: Apper creates the first version of your app, using sample data when needed.

  • Preview it: Once the build is ready, ChatGPT opens a working preview so you can try it.

  • Make changes: Tell Apper what you want to change. It updates the app, rebuilds it, and gives you a new preview.

  • Connect a database when needed: If your app needs real users, saved records, or persistent data, ask ChatGPT to connect a real database.
    caution

    Switching from sample data to a connected database is a one-time, irreversible change that removes the sample data layer.

  • Keep building: After connecting the database, you can continue updating your app's data, permissions, server-side functions, settings, features, and design.

Updating an existing app​

You can also continue working on an app you already created.

For example:

  • "Open my CRM app and add a reports page."
  • "Change the dashboard design."
  • "Add a new field to contacts."
  • "Fix the mobile layout."
  • "Show me the latest preview."

ChatGPT finds the relevant Apper app and makes the requested changes.

Tools​

ChatGPT automatically selects the right Apper tool based on your request.

  • Read-only tools can view information but do not change your app.
  • Write tools can create, update, replace, or delete something in your app.

Authentication and security​

Apper uses OAuth for secure sign-in.

How it works

  • When you connect Apper, ChatGPT takes you to the Apper login page to approve access.
  • Your password stays private. ChatGPT never sees or receives your Apper password.
  • Access is limited to your account. The connection can only access the apps and data available in your authenticated Apper account. It cannot access another person's Apper account or browse the public web through your Apper connection.
  • Secret values such as API keys are entered directly in the Apper dashboard. They never pass through the assistant and are never exposed to the model.

Keep your API keys safe​

Never paste API keys, passwords, or other secret values into the chat. Add them directly to Apper's Secrets page instead.

tip

Simple rule: If it's a secret, add it in Apper - not in the chat.

Privacy and data​

  • Apper only accesses the apps and data in your authenticated Apper account that are needed for the task you ask it to perform.
  • The connection does not request or access your ChatGPT conversation history, raw chat messages, or transcripts. It also does not use a general-purpose context field to access unrelated information.
  • Your Apper connection is limited to what is needed to build and manage your apps.

Database connection is permanent​

Connecting your app to a real database is a one-time, irreversible change. It replaces the sample data layer with a real database, and you cannot switch the app back to sample data afterward.

Before connecting a database, make sure you are happy with your app's basic structure and functionality.

caution

Only connect a real database when you are ready to move from testing with sample data to working with real data.

Troubleshooting​

I don't see Apper in my chat​

Make sure Apper has been added to ChatGPT and is enabled for the conversation.

Also check whether your ChatGPT plan and workspace allow custom MCP apps and the actions you are trying to use.

ChatGPT asks me to reconnect Apper​

Reconnect Apper from your ChatGPT app settings and complete the Apper sign-in process again.

I can't make changes to my app​

Some ChatGPT plans or workspace configurations may limit MCP write actions. Check your plan and workspace permissions.

My app is still building​

ChatGPT can check the current build status. Simply ask:

"Check the status of my Apper app."
