AI agents call governance_report 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.
The tool appears to retrieve governance report data for Korean stocks based on context. No description provided, but the naming pattern and sibling tools that are all read-only disclosure retrieval tools suggest this is a data retrieval tool with no side effects. Confidence is moderate (0.72) due to empty description; if this tool had write or execute capabilities, they would likely be documented.
From the tool's definition Tool name 'governance_report' combined with sibling tools that retrieve AGM-related disclosures (agm_agenda_xml, agm_financials_xml, agm_personnel_xml, etc.) and server description focusing on 'easy access to agm & governance related disclosures' indicate…
Documented attack patterns abuse exactly the kind of access governance_report 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 governance_report:
{
"version": "1",
"default": "deny",
"tools": {
"governance_report": {}
}
}governance_report is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

governance_report. 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 governance_report: 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.
governance_report 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 governance_report 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 governance_report. 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.
governance_report 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.
