WHAT IT DOES

What scan_reminders does on Todos

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

RISK

Why scan_reminders is rated Medium

The tool scans tasks (read) but also upserts (creates or updates) local reminder records, which is a write operation. 'Upsert' means insert or update, making it reversible and fitting the Write category. Severity is medium as misuse could create spurious or erroneous reminder records affecting task management workflows.

RECOMMENDED RULE

The rule that runs scan_reminders safely

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

scan_reminders Rate-limited

scan_reminders 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.
