Why does StackTether build its own tools instead of passing through a vendor's own MCP server?

Own tools let StackTether guarantee read-only access, hide sensitive fields, keep the same tool names on every vendor, write fixed error messages and record exactly which records were read. A vendor's own server can change its tools at any time and may include write actions.

Can I connect two PSAs?

Yes. Connect a primary and a secondary PSA; searches ask the primary first and then the secondary, and record IDs show which PSA they came from.

What API permissions does StackTether need?

Read-only. Each setup guide lists the exact permissions for that vendor and links to the vendor's own documentation.

Supported vendors

StackTether works today with two PSAs: Kaseya BMS and Autotask PSA. ConnectWise PSA, HaloPSA, NinjaOne and Datto RMM are coming soon. Every vendor gets the same vendor-neutral, read-only tools and goes through a live read-only check before it is switched on.
