Attacks that exploit this kind of access
The rule that runs export_calendar_ics 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 export_calendar_ics, this is the rule to start with:
export_calendar_ics is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Todos, apply this rule, and every export_calendar_ics call is checked against it from then on.
