Read all text content from a specific section of a notebook.
AI agents call read_section to retrieve information from OneNote MCP Server 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 text content from a OneNote section with no side effects, fitting the definition of Read category. The low severity reflects that data retrieval alone poses minimal risk unless the notebook contains highly sensitive information, but the tool itself does not modify, execute, or delete anything.
From the tool's definition Tool name 'read_section' and description 'Read all text content from a specific section of a notebook' explicitly describe retrieving data without modification.
Attacks that exploit this kind of access
Read all text content from a specific section of a notebook. It is categorised as a Read tool in the OneNote MCP Server MCP Server, which means it retrieves data without modifying state.
Register the OneNote MCP Server MCP server in PolicyLayer and add a rule for read_section: 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 MCP Server. Nothing to install.
read_section 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 read_section 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 read_section. 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.
read_section is provided by the OneNote MCP Server MCP server (mhzarem/onenote-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
