WHAT IT DOES

What switch_timeline does on Aos

AI agents use switch_timeline to create or update resources in Aos, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Aos environment.

RISK

Why switch_timeline is rated Medium

Switching timelines modifies the active project state, a reversible write operation.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs switch_timeline safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Aos, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For switch_timeline, this is the rule to start with:

switch_timeline Rate-limited

switch_timeline stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
