Connect Climatiq to ChatGPT
Add the Climatiq MCP server to ChatGPT, so it can calculate emissions with Climatiq’s data.
Summary
This guide shows you how to connect ChatGPT to the Climatiq MCP server and check that it works.
The Intro to the Climatiq MCP server explains what it is, when to use it and what the free trial includes.
Prerequisites
- A Climatiq account. Sign up if you don’t have one. New users get a free trial.
- One login to the Climatiq dashboard. Log in to app.climatiq.io at least once before you connect. This first login creates the link between your account and the MCP server.
- A ChatGPT plan with custom MCP servers. Check OpenAI’s documentation for which plans include them.
Steps
Add a custom MCP server
Go to Plugins or Apps, depending on your plan, select Add, then Add custom MCP server. If you don’t see the option, your plan may need Developer mode, or a workspace admin may need to turn it on.
Enter the server details
Name it Climatiq, enter https://mcp.climatiq.io as the URL and set the authentication to OAuth. The URL tells ChatGPT where to find Climatiq’s tools.
Sign in to Climatiq
Sign in with your Climatiq login when the login page opens. ChatGPT then loads the list of Climatiq tools.
Use it in a chat
In a new chat, select Climatiq from the tools or plugins menu.
For details, see OpenAI’s guide to MCP servers in ChatGPT .
How to confirm it worked
- Ask: “What are the emissions of 500 kWh of electricity in Germany?”
- The answer should state that it used Climatiq and give a CO2e value with the emission factor and source behind it.
Troubleshooting
I signed in, but every calculation fails
Log in to app.climatiq.io once, then try again. The first dashboard login is what links your account to the MCP server.
ChatGPT says it has no Climatiq credentials
Reconnect Climatiq in ChatGPT and complete the login.
Where do my usage and saved product footprints go?
It depends on how you connected. If you signed in with your Climatiq login, they go to a project named ‘OAuth Project (Automatically created)’, which Climatiq creates the first time you sign in. If you connected with an API key, they go to the project that key belongs to.
