Setup

ChatGPT connects to MCP servers over the network via developer mode. To configure remote access:

Start Neotoma with a tunnel: follow the tunnel guide to expose your local Neotoma instance over HTTPS. The quickest path:
Code snippet
Copy the exact snippet shown below.
```
neotoma api start --env prod --tunnel
```
Your Neotoma API host
https://
Optional. Enter host only; URLs below use https:// + this host.
Enable developer mode in ChatGPT, then go to Settings → Apps → Advanced settings → Developer mode. On Business plans only admins/owners can enable it; you can also enable it when creating an app via Workspace settings → Apps → Create.
Add Neotoma as a remote MCP server in ChatGPT's developer mode settings, add your tunnel URL (e.g. https://<tunnel-host>/mcp). ChatGPT authenticates via OAuth; the Neotoma API supports the MCP OAuth authorization flow.
