AI agents call list-sections 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 or queries organizational data (sections) from OneNote notebooks. It has no capability to create, modify, delete, or execute operations. The blast radius of misuse is minimal — an AI could only enumerate sections it has access to, which is a read-only operation.
From the tool's definition Tool name is 'list-sections' and description states it 'List sections' with options to filter by notebookId or sectionGroupId.
Attacks that exploit this kind of access
List sections. Provide notebookId to list sections in a notebook, sectionGroupId to list sections in a section group, or omit both to list all sections 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-sections: 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-sections 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-sections 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-sections. 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-sections 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.
