Get the sharing status of a notebook.
AI agents call sharing_status to retrieve information from NotebookLM 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 information about notebook sharing settings, which is a read-only operation with no side effects. It does not create, modify, delete, or execute any actions—it only queries and returns the current sharing status. This fits the 'Read' category definition of retrieving or querying data with no side effects.
From the tool's definition Tool name 'sharing_status' and description 'Get the sharing status of a notebook' indicate a pure query operation that retrieves metadata about a notebook's sharing configuration without modifying, deleting, or executing any operations.
Attacks that exploit this kind of access
Get the sharing status of a notebook. It is categorised as a Read tool in the NotebookLM MCP Server MCP Server, which means it retrieves data without modifying state.
Register the NotebookLM MCP Server MCP server in PolicyLayer and add a rule for sharing_status: 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 NotebookLM MCP Server. Nothing to install.
sharing_status 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 sharing_status 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 sharing_status. 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.
sharing_status is provided by the NotebookLM MCP Server MCP server (pavelguzenfeld/notebooklm-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
