AI agents call google_scholar to retrieve information from Noapi Google Search without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Google Scholar is an academic search engine that retrieves and queries scholarly publications, citations, and research metadata. This is a passive data retrieval operation with no side effects, no code execution, no data modification, and no financial transactions.

PolicyLayer is an MCP gateway — it sits between your AI agents and Noapi Google Search, and nothing reaches the server without passing your rules. This is the rule we recommend for google_scholar:
{
"version": "1",
"default": "deny",
"tools": {
"google_scholar": {}
}
}google_scholar is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Yes. Add a rate_limit block to the google_scholar 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 google_scholar. 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.
