AI agents use infographic_create to create or update resources in Notebooklm — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Notebooklm environment.
The tool creates and generates new data (infographic output) based on existing sources, which is a Write operation. It does not delete data (Destructive), execute arbitrary code (Execute), move money (Financial), or merely retrieve information (Read).
From the tool's definition Tool description states 'Generate an infographic' — a create operation that produces new content/artifacts from notebook sources.
Documented attack patterns abuse exactly the kind of access infographic_create gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Notebooklm, and nothing reaches the server without passing your rules. This is the rule we recommend for infographic_create:
{
"version": "1",
"default": "deny",
"tools": {
"infographic_create": {
"limits": [
{
"counter": "infographic_create_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}infographic_create stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Generate an infographic from notebook sources. It is categorised as a Write tool in the Notebooklm MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Notebooklm MCP server in PolicyLayer and add a rule for infographic_create: 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. Nothing to install.
infographic_create 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 infographic_create 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 infographic_create. 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.
infographic_create is provided by the Notebooklm MCP server (moodrobotics/notebooklm-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Notebooklm, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
