AI agents call get_book_info to retrieve information from Wikidocs without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and retrieves data about books—metadata and page content—with no side effects. It is a foundational read operation that fetches information needed for downstream operations. The description explicitly states it attempts to get latest data and falls back to cache, both read-only behaviors. No creation, modification, deletion, or execution occurs.
From the tool's definition Tool description states it 'retrieves' (조회) book information including 'title, summary, page count' and 'all page data.' The Korean verb 조회 means 'to look up' or 'to query,' confirming read-only retrieval. No mutations, deletions, or executions are mentioned.
Documented attack patterns abuse exactly the kind of access get_book_info gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Wikidocs, and nothing reaches the server without passing your rules. This is the rule we recommend for get_book_info:
{
"version": "1",
"default": "deny",
"tools": {
"get_book_info": {}
}
}get_book_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

특정 책의 기본 정보(제목, 요약, 페이지 수)와 모든 페이지 데이터를 조회합니다. 항상 최신 데이터를 가져오려고 시도하며, API 요청이 실패할 경우에만 캐시를 사용합니다. 이후 검색이나 구조 분석 도구를 사용하기 위해 필요한 첫 번째 단계입니다. It is categorised as a Read tool in the Wikidocs MCP Server, which means it retrieves data without modifying state.
Register the Wikidocs MCP server in PolicyLayer and add a rule for get_book_info: 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 Wikidocs. Nothing to install.
get_book_info 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 get_book_info 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 get_book_info. 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.
get_book_info is provided by the Wikidocs MCP server (ychoi-kr/wikidocs-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Wikidocs, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
