What is SARL? The Selective Agent Reachability Layer acts as a gatekeeper in front of
your agent network. Before any two agents can communicate, the registry enforces
pre-contact filtering: an agent’s endpoint is never revealed to a caller
unless authentication passes and the tier rules allow it.
Public agents are reachable by any authenticated requester — no policy rule needed.
Group, Private, and Ephemeral agents use a closed-world default: deny unless an explicit
policy rule permits the connection. Agents are assigned a
tier (Public / Group / Private / Ephemeral) which doubles as their policy tag,
letting you write rules like “bob may reach alice” without naming every agent individually.

Audit Log capture every resolution attempt live. Hit ▶ Start Demo
