You can read the ChatGPT setup steps without signing in.

Sign in when you are ready to create a private token, or replace the placeholder in the command below with an existing Great Arrow token.

Step 1 · No setup needed

ChatGPT handles sign-in for you on the next step.

Step 2 · Add it to ChatGPT

ChatGPT handles sign-in automatically — you just paste one URL.

This is a private developer-mode custom app, not an approved or publicly listed Great Arrow plugin. ChatGPT on the web must expose developer mode for your account or workspace.

Open ChatGPT developer mode ↗

Open ChatGPT on the web. MCP apps are not available in the ChatGPT mobile apps.
Enable Developer mode. Depending on your rollout, use Settings → Security and login orSettings → Apps → Advanced settings. In a managed workspace, an admin may first need to enable it underWorkspace settings → Permissions & Roles.
Open Settings → Apps → Create and choose a custom MCP app. If your account still uses the older developer interface, open Plugins → + instead.
Enter a name such as Great Arrow Digital, paste the URL below as the remote MCP server, choose OAuth if ChatGPT asks for an authentication method, then select Scan Tools.
Complete the Great Arrow sign-in, choose the workspace to connect, wait for the tool scan, and select Create(or Create connection in the older UI).
Start a new ChatGPT web chat, select the new draft app from the tools menu, and ask: “Search my Great Arrow workspace for my latest project risks.”
If Developer mode, Apps → Create, or Plugins → + is missing, the account plan or workspace policy is blocking the setup. Ask the OpenAI workspace owner/admin; do not treat this as a Great Arrow login failure.
