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 and lists sections from an existing notebook. It is a read-only operation that queries data structure without creating, modifying, deleting, or executing any operations. The blast radius of misuse is minimal—an attacker could enumerate notebook structure but not alter or delete content.
From the tool's definition Tool description states 'List sections in a specific notebook' — a query operation with no modification. The server description emphasizes 'reading and listing content.' No side effects or data changes.
Documented attack patterns abuse exactly the kind of access list_sections gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Onenote, and nothing reaches the server without passing your rules. This is the rule we recommend for list_sections:
{
"version": "1",
"default": "deny",
"tools": {
"list_sections": {}
}
}list_sections is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List sections in a specific notebook. 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 (purpleslurple/onenote-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
