# treg.to

Treg documents an MCP endpoint at this host for compatible clients.

Run by Treg · Ports: 443 TCP · Checked: 3 November 2026

## Short answer

Treg provides a hosted endpoint for accessing a catalog of external tools and data.

Block with care

Blocking this host can interrupt Treg integrations that depend on it.

Matches

`treg.to`

A name with `*.` covers every name under it: `*.push.apple.com` matches `1-courier.push.apple.com`.

## What it serves

Its documentation describes searching a catalog and calling tools through the service.

The specific provider, data requested and cost depend on the tool and request.

A configured application or AI tool can connect to this endpoint when using the relevant integration.

A hostname identifies a destination but does not reveal the contents of encrypted traffic.

## What breaks if you block it

Block with care

Blocking this host can interrupt Treg integrations that depend on it.

What breaks if you block it

- An app or assistant using treg.to may fail to connect.
- Tasks depending on this integration may stop until the connection is restored.

With Kilobat Pro and the network filter, you can block a host for every app or for one app: in Connections, select a connection and choose Block. Apple’s own services are never blocked by Kilobat’s [Protection](https://kilobat.app/docs/blocking#protection) lists.

## Notes

A service can use other hostnames too. Blocking this host alone does not necessarily block every feature.

If the connection is unexpected, inspect the originating process and review its configured integrations.
