AI agents call list-section-groups 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 OneNote organizational structure (section groups) without creating, modifying, deleting, or executing any operations. It is purely informational, making it a Read category tool with low severity since exposure carries minimal risk to data integrity or security.
From the tool's definition Tool description states it 'List section groups' and 'lists section groups in that notebook' or 'across all notebooks'.
Attacks that exploit this kind of access
List section groups. When notebookId is provided, lists section groups in that notebook. Otherwise lists all section groups across all notebooks. It is categorised as a Read tool in the Onenote MCP Server, which means it retrieves data without modifying state.
Register the Onenote MCP server in PolicyLayer and add a rule for list-section-groups: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Onenote. Nothing to install.
list-section-groups 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 list-section-groups 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 list-section-groups. 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.
list-section-groups is provided by the Onenote MCP server (jacob-hartmann/onenote-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
