# Require Scope • AI Agent SDK

> require_scope: Enforce that at least one scope identifier is provided.

# require\_scope

<div className="flex items-center gap-2">
  <Badge color="teal">Function</Badge>

> This function is defined in the [**protocols**](../modules/protocols) module.

Enforce that at least one scope identifier is provided.

Shared helper so every knowledge adapter enforces the same tenant-scope
contract (mem0 already did via its own `_check_scope`). Without this, an
unscoped call that raises `ScopeRequiredError` on the mem0 backend would
silently return or wipe *every* tenant's data on the Chroma/SQLite backends
— a data-loss/leak hazard depending purely on which backend is installed.
