reset_session

THE RISK

Critical Risk

Resetting a session implies destroying the current session state irreversibly. Session data, authentication tokens, and any in-progress work would be lost and cannot be recovered. This is a destructive action with no indication of reversibility. Confidence is moderate because the description is minimal and does not clarify exactly what data is lost.

From the tool's definition reset_session - 'Reset a session'

Documented attack patterns abuse exactly the kind of access reset_session gives an agent:

HOW TO CONTROL RESET_SESSION

PolicyLayer is an MCP gateway — it sits between your AI agents and NotebookLM MCP Structured, and nothing reaches the server without passing your rules. This is the rule we recommend for reset_session:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "reset_session"
  ]
}

reset_session disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register NotebookLM MCP Structured — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
