AI agents call list_industries to retrieve information from Financial Reports MCP Server 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 or enumerate a list of industries from the Financial Reports API. This is a read operation with no side effects—it queries existing data without modification, deletion, or execution of arbitrary code. The empty description reduces confidence slightly, but the semantic name and server context strongly suggest a simple data retrieval operation typical of a financial data API.
From the tool's definition Tool name is 'list_industries' and sibling tools include read-only operations like 'get_company_detail', 'get_filing_detail', 'get_industry', 'get_sector'. The naming pattern and context indicate data retrieval.
Documented attack patterns abuse exactly the kind of access list_industries gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Financial Reports MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_industries:
{
"version": "1",
"default": "deny",
"tools": {
"list_industries": {}
}
}list_industries is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

list_industries. It is categorised as a Read tool in the Financial Reports MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Financial Reports MCP Server MCP server in PolicyLayer and add a rule for list_industries: 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 Financial Reports MCP Server. Nothing to install.
list_industries 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 list_industries 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 list_industries. 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.
list_industries is provided by the Financial Reports MCP Server MCP server (itisaevalex/financial-reports-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Financial Reports MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
