AI agents call dilutive_issuance 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 dilutive issuance data from AGM/governance disclosures, consistent with the server's purpose of providing 'easy access' to such documents. No description suggests write, execute, or destructive operations. The empty description reduces confidence but the name and context indicate a read operation retrieving financial disclosure data.
From the tool's definition Tool name 'dilutive_issuance' and server context (governance/AGM disclosures for Korean stocks) suggest data retrieval of issuance information. Description is empty, limiting certainty.
Documented attack patterns abuse exactly the kind of access dilutive_issuance 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 dilutive_issuance:
{
"version": "1",
"default": "deny",
"tools": {
"dilutive_issuance": {}
}
}dilutive_issuance is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

dilutive_issuance. 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 dilutive_issuance: 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.
dilutive_issuance 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 dilutive_issuance 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 dilutive_issuance. 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.
dilutive_issuance 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.
