AI agents call get-section-group to retrieve information from Onenote without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries information about OneNote section groups and their contents. It has no side effects, does not create, modify, or delete data, and does not execute external code or operations. It is purely informational, fitting the Read category with low severity since unauthorized access to OneNote structure is less critical than modifications or deletions.
From the tool's definition Tool name 'get-section-group' and description 'Get detailed information about a specific section group, including its sections and nested section groups.' indicate a retrieval operation with no modification or deletion of data.

get-section-group is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get-section-group rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get-section-group. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
