THE RISK

Low Risk

Why get_company_concept needs a policy

This tool retrieves financial concept data from the SEC database without modifying, executing code, deleting, or transferring funds. It is a straightforward read operation typical of financial data APIs. The low severity reflects minimal risk if misused by an agent—the worst outcome would be unauthorized disclosure of publicly available SEC filing data.

From the tool's definition Tool description states 'Get specific financial concept data for a company' — a retrieval operation with no side effects. The verb 'Get' and the context of querying SEC EDGAR database for financial facts indicate a read-only query.

POLICY

How to control get_company_concept

PolicyLayer is an MCP gateway — it sits between your AI agents and SEC MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_company_concept:

policy.json

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

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

Create a free account and register SEC MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
