AI agents call corporate_restructuring 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.
Given the server's purpose (providing disclosure access to investors) and the pattern of sibling tools that query/retrieve AGM and governance data, this tool most likely retrieves corporate restructuring information from disclosures. Without explicit evidence of write, delete, or execute operations, and absent a description, the safest classification is Read.
From the tool's definition Tool name is 'corporate_restructuring' with empty description. Context suggests this server provides governance and AGM disclosures for Korean stocks. The sibling tools (agm_agenda_xml, agm_financials_xml, agm_personnel_xml, etc.) are all retrieval-oriented.
Documented attack patterns abuse exactly the kind of access corporate_restructuring 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 corporate_restructuring:
{
"version": "1",
"default": "deny",
"tools": {
"corporate_restructuring": {}
}
}corporate_restructuring is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

corporate_restructuring. 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 corporate_restructuring: 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.
corporate_restructuring 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 corporate_restructuring 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 corporate_restructuring. 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.
corporate_restructuring 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.
