AI agents call proxy_litigation 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 designed to retrieve or query litigation information related to proxy statements and corporate governance disclosures. Given the server's purpose (providing data access for investors and stewardship specialists) and naming pattern of sibling tools (all agm_ and governance-related), this is most likely a data retrieval operation with no side effects.
From the tool's definition Tool name 'proxy_litigation' and context of server serving 'agm & governance related disclosures for Korean stocks' suggests retrieval of litigation data. The description is empty, reducing confidence.

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 proxy_litigation:
{
"version": "1",
"default": "deny",
"tools": {
"proxy_litigation": {}
}
}proxy_litigation is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

proxy_litigation. 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 proxy_litigation: 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.
proxy_litigation 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 proxy_litigation 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 proxy_litigation. 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.
proxy_litigation 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.
