WHAT IT DOES

What get_company_news does on Yfnhanced

AI agents call get_company_news to retrieve information from Yfnhanced 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 get_company_news needs a policy

This tool performs a simple data retrieval operation from a news API. It queries existing public news content and returns structured information without any side effects, reversible modifications, or irreversible changes. The 'handles cases where news API fails silently' clause indicates error handling for read operations, not data manipulation.

From the tool's definition Tool description states it 'Retrieve[s] recent news articles' with no mention of modification, deletion, execution, or financial transactions. The tool only gathers and returns news data (title, publisher, link, tickers).

POLICY

How to control get_company_news

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

policy.json

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

get_company_news 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 Yfnhanced — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
