Your browser opens. Sign in to Meerie if you are asked. On the Connect Codex? page choose View only or View and edit, then click Allow.When it works, the browser says Authentication complete. You may close this window.

The ChatGPT tab on the Connect page gives these steps. They are shown as the page words them, and ChatGPT changes its menu names from time to time, so look for the place that adds a custom MCP connector.

2. Name it Decision Intelligence, paste the address, and choose OAuth for authentication.
3. Create it, then sign in to Meerie, choose the access level and click Allow.

Open the Other tools tab on the Connect an AI assistant page in Meerie. It shows what to enter for other assistants. You will need the address https://di.meerietechnology.com/mcp.

​

Disconnect

​

If it does not work

• The address must be exactly https://di.meerietechnology.com/mcp, with no spaces.
• Finish the browser steps. The connector only works after you click Allow.
• If a tool is blocked, check Tool permissions on the connector page in Claude.

​

What to do next

​

Good to know

• The assistant works on the same decisions you see in the browser. A change it makes is the same record you see there.
• Any accepted change creates a new version of the model. Nothing is edited in place, and earlier runs are marked out of date so you know to run again.
• Treat results as you would from Dave: the numbers come from the engine, not from the AI’s own arithmetic. Ask for the run ID behind any figure.
