Use ChatGPT with DataDoe MCP

Use this guide to connect DataDoe MCP to ChatGPT as a custom MCP app. You can then query your DataDoe workspace from ChatGPT.

Before you start

• Use ChatGPT on the web. The plugin settings described below live there. The desktop app's menu layout can differ, and mobile apps do not expose them.
• Plus and Pro users can connect custom MCP apps in Developer mode. Reading and fetching data works fully. Write actions (DataDoe Actions) may require a Business, Enterprise, or Edu workspace. OpenAI's docs are inconsistent here, so test on your account.
• Business, Enterprise, and Edu workspaces support full MCP apps, including write and modify actions. An admin or owner must enable Developer mode before creating or publishing an app.
• In Enterprise and Edu workspaces, an admin can use role-based access control (RBAC) to give selected members access to Developer mode and apps.

Plugin names in Settings. ChatGPT has renamed this area more than once. Depending on your account you will see Plugins, Apps, or Connectors in Settings. They all refer to the same feature. This guide uses the labels from the current web UI.

During setup, ChatGPT redirects you to DataDoe so you can sign in and approve access.

Step 1: Copy the MCP server URL

Copy this URL: https://mcp.datadoe.com/mcp/v1.

Step 2: Enable ChatGPT Developer mode

Plus and Pro

1. Go to chatgpt.com.
2. Open Settings → Plugins and select Developer mode (on some accounts the path is Settings → Apps → Advanced settings). ChatGPT takes you to Security and login → Developer mode.
3. Enable the Developer mode toggle. It is marked Elevated risk. Read the warning before continuing.

Business, Enterprise, and Edu

1. As a workspace admin or owner, go to Workspace settings → Permissions & Roles → Connected Data.
2. Enable Developer mode / Create custom MCP connectors.
3. In Enterprise and Edu workspaces, configure RBAC if only selected members should create or use custom apps.

Step 3: Create the DataDoe MCP app

1. With Developer mode on, go to Settings → Plugins (or Apps) and select Create. Workspace admins may instead use Workspace settings → Apps → Create.

2. Set Name to DataDoe.

3. Add a short description, such as Query Amazon data in DataDoe.

4. In MCP Server URL, paste the URL from Step 1.

5. Keep OAuth as the authentication method.

6. Acknowledge the custom app risk warning.

7. Select Create.

Step 4: Test and publish the app

1. Test the app privately to confirm that its tools work as expected. In a workspace, new apps sit in a Drafts tab until published.
2. If you are creating the app for a Business, Enterprise, or Edu workspace, select Publish to make the approved app available to the workspace.
3. Review the risk warning and confirm publication.

Publishing is a workspace admin action. A Plus or Pro user's custom MCP app is for their own use and does not need to be published.

Step 5: Test the connection

1. Go back to chatgpt.com and start a new chat.
2. Enable the app for the chat: select the + button → More → Developer mode, then tick DataDoe in the list of apps the conversation may use.
3. Send a prompt that uses DataDoe data. Naming the app helps ChatGPT pick the right tools. For example:

Show me my Amazon Seller Central sales for the last 7 days.

If ChatGPT returns DataDoe data, the connection is working.

Security

• ChatGPT treats custom MCP apps as potentially sensitive integrations. Only connect or publish apps that you trust.
• ChatGPT uses OAuth to sign in to DataDoe and approve access.
• Access is scoped to the permissions of the DataDoe user who approved the connection.
• To revoke access, go to DataDoe MCP Integrations (opens in a new tab) and remove or unpublish the app in your ChatGPT workspace settings.

Troubleshooting

I cannot find Developer mode or Create

• Confirm you are using chatgpt.com in a web browser.
• On Plus or Pro, enable it via Settings → Plugins → Developer mode (some accounts show Settings → Apps → Advanced settings).
• On Business, Enterprise, or Edu, ask a workspace admin or owner to enable custom MCP connectors. Enterprise and Edu workspaces may also require RBAC access.

OAuth sign-in fails or keeps redirecting

• Allow pop-ups and redirects for chatgpt.com and DataDoe.
• Temporarily disable ad or tracking blockers that might interfere with OAuth flows.
• Try a private browsing window to rule out extension issues.

I created the app but cannot add it to a chat

• In a workspace, make sure an admin has tested and Published the app.
• If you are in an Enterprise or Edu workspace, confirm that RBAC grants you access to the app.
