# Linking Agents

AdaptixC2 supports agent chains (linking agents). These linked agents receive their commands and send their output through the parent agent in their chain. This type of chaining is useful to control which sessions egress a network and to emulate a disciplined actor who restricts their communication paths inside of a network to something plausible.

For a linked agent, the External field will contain the parent agent ID and link name instead of the external IP address. Registered but not currently linked agents are marked as Unlink.
