Setup guide for MCP clients (beta) (Oct 26 2026) 

The following instructions are a guide to walk you through setting up an MCP connector within your AI chat application for your organization. The instructions are current as of October 2026. The specific steps or labels within your chosen application may vary as those clients are updated over time, but the inputs needed to configure the connection should not change.

The Beta is currently available in read-only mode, with write access coming soon!

Permissions for individual users in PX will also be honored so based on the permission's granted to a PX User those endpoints will be the details seen.
