You need a PaxFlow account with AI assistant access, and a ChatGPT account.
PaxFlow is waiting for approval in ChatGPT's plugin directory. Until it's listed, add PaxFlow yourself as a custom plugin. It works the same way.
Add PaxFlow as a custom plugin
In ChatGPT, open Plugins in the left menu.
Click Add, then Add custom MCP server.
Enter the name PaxFlow and, under Connection, the server URL
https://mcp.paxflow.io/mcpLeave Authentication set to OAuth.
Tick I understand and want to continue, then click Create as a plugin.
Sign in with your PaxFlow email and password.
PaxFlow opens Allow ChatGPT to use PaxFlow. Choose what ChatGPT can see and change, then click Allow.
ChatGPT never gets more access than your own PaxFlow account has.
On a ChatGPT Business or Enterprise plan, a workspace admin may have to allow custom plugins first.
Add PaxFlow from the plugin directory
Once PaxFlow is listed:
In ChatGPT, open Plugins in the left menu.
Search for PaxFlow, select it and connect it.
Sign in with your PaxFlow email and password.
PaxFlow opens Allow ChatGPT to use PaxFlow. Choose what ChatGPT can see and change, then click Allow.
If you added PaxFlow as a custom plugin earlier, uninstall it first.
Try it
Start a new chat and ask:
"What can you access in PaxFlow?"
"Show me tomorrow's departures."
"Find the booking for Anna Jónsdóttir."
ChatGPT asks for your approval before it runs a tool that changes data.
If you belong to more than one company
Name the company in your question, for example "Show tomorrow's departures for Glacier Tours".
Disconnect
In ChatGPT, open Settings, then Plugins, select PaxFlow and click Uninstall.
