RISK

Why update_note is rated Medium

This tool creates or modifies data (Apple Notes content) in a reversible manner. While updates are not destructive and data remains intact and recoverable, the tool can alter user information. The confirm=true requirement provides a safeguard against accidental invocation.

From the tool's definition Tool description explicitly states 'Updates an existing note' and 'Change the title and/or body', indicating reversible modification of data. Requires confirm=true safeguard.

RECOMMENDED RULE

The rule that runs update_note safely

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

update_note Rate-limited

update_note 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.
