Create a new page in a OneNote section. The content should be provided as HTML. The HTML must be valid XHTML with a title in the <title> tag. At minimum, provide a title; the body can be empty for a blank page.
AI agents use create-page to create or update resources in Onenote — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Onenote environment.
The tool creates new pages in OneNote notebooks, which is a reversible write operation. It does not delete data (thus not Destructive), does not execute arbitrary code (thus not Execute), does not move money (thus not Financial), and is not merely reading data (thus not Read).
From the tool's definition Tool name is 'create-page' and description states 'Create a new page in a OneNote section' with content provided as HTML. This is a create operation that adds new data to OneNote.
Attacks that exploit this kind of access
Create a new page in a OneNote section. The content should be provided as HTML. The HTML must be valid XHTML with a title in the <title> tag. At minimum, provide a title; the body can be empty for a blank page. It is categorised as a Write tool in the Onenote MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Onenote MCP server in PolicyLayer and add a rule for create-page: 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.
create-page is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create-page 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 create-page. 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.
create-page 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.
