WHAT IT DOES

What list_sectors does on Financial Reports MCP Server

AI agents call list_sectors 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 RISK

Low Risk

Why list_sectors needs a policy

This tool retrieves static reference data (GICS sector classifications) from the Financial Reports API. It is a read-only query operation that has no side effects, cannot modify data, and poses no execution or financial risk. The low severity reflects that sector classification data is public, non-sensitive reference information.

From the tool's definition Tool name 'list_sectors' and description 'List all available GICS sectors' indicate a retrieval operation that queries and returns sector classification data without modification or side effects.

POLICY

How to control list_sectors

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_sectors:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_sectors": {}
  }
}

list_sectors is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
