AI agents call coord-to-address 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 is a pure data retrieval operation that queries Kakao's mapping database to resolve coordinates to human-readable addresses. It performs no write, delete, execute, or financial operations. The only risk is information disclosure of addresses corresponding to specific coordinates, which is a low-severity read operation. Reverse geocoding is widely available as a public service with minimal security impact.
From the tool's definition Tool converts coordinates (longitude, latitude) to addresses (road name, lot number) via Kakao Map reverse geocoding service.
Documented attack patterns abuse exactly the kind of access coord-to-address gives an agent:
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 coord-to-address:
{
"version": "1",
"default": "deny",
"tools": {
"coord-to-address": {}
}
}coord-to-address is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

좌표(경도, 위도)를 주소(도로명, 지번)로 변환합니다. It is categorised as a Read tool in the Kakao API MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Kakao API MCP Server MCP server in PolicyLayer and add a rule for coord-to-address: 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 Kakao API MCP Server. Nothing to install.
coord-to-address 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 coord-to-address 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 coord-to-address. 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.
coord-to-address 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.
Free to start. No card required.
