AI agents call search-cafe to retrieve information from Kakao API MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only search query against Daum's cafe content index. It retrieves data without creating, modifying, deleting, or executing any external operations. The blast radius is minimal since it cannot change state or access sensitive systems beyond public search results. Consistent with sibling tools (search-web, search-image, search-blog) which are all information retrieval operations.
From the tool's definition Tool name 'search-cafe' and description indicate it searches Daum (Korean search engine) for cafe posts/articles. The description states '다음(Daum) 검색에서 카페 글을 검색합니다' (searches for cafe articles/posts on Daum search).

PolicyLayer is an MCP gateway — it sits between your AI agents and Kakao API MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search-cafe:
{
"version": "1",
"default": "deny",
"tools": {
"search-cafe": {}
}
}search-cafe 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 search-cafe 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-cafe. 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-cafe is provided by the Kakao API MCP Server MCP server (jeong-sik/kakao-api-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Kakao API MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
