How to connect to MCP

Connect Claude or another AI assistant to your Meerie decisions.

Once an AI assistant is connected, it can list your decisions, read a model, run a simulation and write a memo. It works on the same records you see in the browser.

You do not install anything. You add one address to your assistant, then sign in and allow it.

Choose View only unless you want the assistant to change your work. View and edit lets it create and change decisions, save notes and runs, and restore earlier versions.

Start in Meerie

1. Open Connect AI assistant

   Open the account menu, then choose Connect AI assistant.

   
2. Pick your assistant

   The Connect an AI assistant page has a tab for Claude, ChatGPT and Other tools. Each tab shows the steps and the address to copy. Click Copy to copy the address.

   

   The address is:

   https://di.meerietechnology.com/mcp
   

   The Your connections list on this page shows what is connected. It says “Nothing is connected yet” until you finish.

Now follow the steps for your assistant.

Claude

1. Add a custom connector in Claude

   In Claude, open Settings, then Customize, then the Connectors tab. Click Add, then Add custom connector.

   Type a name, for example Decision Intelligence. Paste the address. Click Continue.

   
2. Continue in your browser

   Your browser opens a page that says Finish connecting a connector? Click Continue connecting.

   

   This page only appears because you started in Claude. If you did not start it, click Not now.
3. Choose what Claude can do

   Sign in to Meerie if you are asked. On the Connect Claude? page choose View only or View and edit, then click Allow.

   

   The page also says what Claude can never do. It only sees the decisions and workspaces you can open. It cannot change your account or password, share decisions, or manage workspace members.

4. Check that it is connected

   Back in Claude, the connector is listed in Settings, Customize, Connectors. Open it to see its address and Tool permissions. Each tool has its own permission buttons.

   

   In a chat, click the + button, then Connectors. Make sure the connector is switched on.

   
5. Try it

   Ask Claude: Use the DI MCP, list out the workspaces for me. Claude shows that it listed the workspaces, then answers with a table.

   

Codex

These steps are for the Codex app. In the app, open Settings, then Plugins.

1. Add an MCP server

   The Plugins page says “Manage plugins, skills, and MCPs”. Click Add.

   

   Choose Add MCP server.

   
2. Fill in the form

   On Connect to a custom MCP, enter a name, for example decision_intelligence. Set Type to Streamable HTTP. Paste the address into URL. Leave Bearer token env var and Headers empty.

   
3. Authenticate

   Your server now appears under Servers. Click Authenticate.

   
4. Choose what the app can do

   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.

   

ChatGPT

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.

1. In ChatGPT, open Settings, then Apps & Connectors, then Advanced. Turn on Developer mode, then choose Create.

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.

   

Other tools

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

You can disconnect an assistant at any time. In Claude, open the connector and click Disconnect. The Connect an AI assistant page in Meerie also lists your connections.

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

Follow the MCP guides: ask about a decision, build a model, run simulations, research an input and write a memo.

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.
