MCP server connections are only available for paid ChatGPT plans: Plus, Pro, Team, and Enterprise.
ChatGPT supports MCP servers through custom connectors in the web interface. Follow these steps to connect the data.gouv.fr MCP server.
1

Access settings

Open ChatGPT in your browser and navigate to Settings.From the settings menu, go to Apps and connectors.
2

Enable Developer mode

In the settings sidebar, open Advanced settings.Toggle Developer mode to enable it. This allows you to add custom MCP connectors.
3

Add a new connector

Return to Settings > Connectors.Click Browse connectors, then click Add a new connector.
4

Configure the data.gouv.fr connector

In the connector configuration screen:
  1. Set the URL to: 
    https://mcp.data.gouv.fr/mcp
  2. Optionally, give the connector a descriptive name like “data.gouv.fr”
  3. Click Save to activate the connector
5

Verify the connection

The connector should now appear in your list of active connectors.You can verify it’s working by starting a new conversation and asking:
“What tools do you have for searching French open data?”
ChatGPT should list the available data.gouv.fr tools like search_datasets, get_dataset_info, and others.

​
Using the tools

Once connected, you can ask ChatGPT questions about French open data:
  • “Search for datasets about public transportation in Paris”
  • “Show me recent datasets about housing prices”
  • “Find APIs related to geographic data”
ChatGPT will automatically use the appropriate data.gouv.fr tools to answer your questions.

​
Self-hosting

If you’re running your own instance of the MCP server, replace https://mcp.data.gouv.fr/mcp with your server’s URL in the connector configuration. For local development, use http://127.0.0.1:8000/mcp (or your custom port).

​
Troubleshooting

​
Connector not working

If the connector doesn’t appear to be working:
  1. Verify you have a paid ChatGPT plan (Plus, Pro, Team, or Enterprise)
  2. Check that Developer mode is enabled in Advanced settings
  3. Ensure the URL is correct: https://mcp.data.gouv.fr/mcp
  4. Try removing and re-adding the connector
  5. Refresh your browser and start a new conversation

​
Tools not appearing

If ChatGPT doesn’t recognize the tools:
  • Make sure the connector is saved and active
  • Try explicitly mentioning “data.gouv.fr” in your question
  • Check that you’re in a new conversation (tools may not appear in existing chats)
