WHY IT NEEDS A POLICY

Why createNotebookEntry needs a policy

Creating a notebook entry is a reversible write operation that adds data to an RSpace instance. It does not execute code, delete data, or move money. Medium severity reflects that unauthorized entry creation could pollute or compromise research data integrity, but the impact is scoped to the notebook and reversible.

From the tool's definition Tool name 'createNotebookEntry' indicates creation of a new entry in a notebook. Sibling tools like 'createNewNotebook' and 'renameDocumentOrNotebookEntry' on this RSpace MCP server confirm this server handles data creation and modification.
