WHAT IT DOES

What notion_list_workspaces does on Local

AI agents call notion_list_workspaces to retrieve information from Local without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why notion_list_workspaces is rated Low

This is a read-only operation that queries and returns information about workspaces and member metadata. No data is created, modified, deleted, or executed. The information retrieved is already cached locally on the Mac.

From the tool's definition Tool explicitly 'Lists the Notion workspaces' and 'their members (names and emails)' — retrieves cached data without modification or side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs notion_list_workspaces safely

notion_list_workspaces Allowed

notion_list_workspaces is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Local, apply this rule, and every notion_list_workspaces call is checked against it from then on.
