AI agents call div_search to retrieve information from Open Proxy without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool searches and retrieves dividend-related public disclosures for Korean stocks—a read-only information lookup with no side effects, data modification, code execution, or financial transaction capability. The highest risk is unauthorized access to potentially material information, which is inherent to read operations but does not elevate severity beyond low in isolation.
From the tool's definition Tool name 'div_search' and description indicate a search function for dividend-related disclosures (배당/배당금/dividend/DPS).
Documented attack patterns abuse exactly the kind of access div_search gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Open Proxy, and nothing reaches the server without passing your rules. This is the rule we recommend for div_search:
{
"version": "1",
"default": "deny",
"tools": {
"div_search": {}
}
}div_search is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

desc: 배당/배당금/dividend/DPS 관련 공시 검색 (현금배당 결정, 중간배당 등). It is categorised as a Read tool in the Open Proxy MCP Server, which means it retrieves data without modifying state.
Register the Open Proxy MCP server in PolicyLayer and add a rule for div_search: 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 Open Proxy. Nothing to install.
div_search 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 div_search 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 div_search. 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.
div_search is provided by the Open Proxy MCP server (marcoyou/open-proxy-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Open Proxy, 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.
