AI agents call search_book to retrieve information from Naver Search MCP Server without modifying anything β typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs search and information retrieval from Naver's book database. It retrieves existing data (reviews, author info, publication details) without creating, modifying, deleting, or executing anything. The mention of checking current time via get_current_korean_time is for filtering results by recency, not for executing operations.
From the tool's definition Tool description explicitly states it "Search for books", "Find book reviews", "author information", "publication details", and "reading recommendations" β all read-only retrieval operations with no modification or side effects.
Documented attack patterns abuse exactly the kind of access search_book gives an agent:
PolicyLayer is an MCP gateway β it sits between your AI agents and Naver Search MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search_book:
{
"version": "1",
"default": "deny",
"tools": {
"search_book": {}
}
}search_book is read-only, so it stays allowed β but everything else on the server is denied unless you say otherwise.

Register the Naver Search MCP Server MCP server in PolicyLayer and add a rule for search_book: 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 Naver Search MCP Server. Nothing to install.
search_book 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 search_book 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 search_book. 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.
search_book is provided by the Naver Search MCP Server MCP server (isnow890/naver-search-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Naver Search MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
