Fetch latest news articles for a stock symbol with relevance scoring.
AI agents call get_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.
This tool retrieves and queries news data—a read-only operation with no side effects. It fetches articles for a stock symbol and scores them for relevance, but does not create, modify, delete, or execute any operations. The low severity reflects that retrieving publicly available news poses minimal risk even if misused by an AI agent.
From the tool's definition Tool name 'get_news' and description 'Fetch latest news articles' indicate data retrieval with 'relevance scoring' as analysis. No modification, deletion, execution, or financial transaction occurs.
Documented attack patterns abuse exactly the kind of access get_news gives an agent:
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_news:
{
"version": "1",
"default": "deny",
"tools": {
"get_news": {}
}
}get_news is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Fetch latest news articles for a stock symbol with relevance scoring. It is categorised as a Read tool in the Yfnhanced MCP Server, which means it retrieves data without modifying state.
Register the Yfnhanced MCP server in PolicyLayer and add a rule for get_news: 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 Yfnhanced. Nothing to install.
get_news 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 get_news 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 get_news. 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.
get_news is provided by the Yfnhanced MCP server (kanishka-namdeo/yfnhanced-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Yfnhanced, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
