WHAT IT DOES

What sync_external_clock does on Aos

AI agents use sync_external_clock 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 sync_external_clock is rated Medium

This tool modifies the project's tempo/clock settings by synchronizing it to an external live source. It creates or modifies a project-level configuration (tempo locking) in a reversible way — it can be unlocked or changed again. No data is deleted, no code is executed arbitrarily, and no financial transaction occurs.

From the tool's definition Lock the project tempo to a live source so beat-synced visuals follow the music.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs sync_external_clock 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 sync_external_clock, this is the rule to start with:

sync_external_clock Rate-limited

sync_external_clock 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.
