Why scrape_stock_news needs a policy

This tool performs information retrieval (scraping news articles) from public sources. While scraping can raise ethical/legal concerns depending on target sites' terms of service, functionally it is a read-only operation that queries and retrieves data without side effects, modification, or deletion. The blast radius of misuse is limited to accessing news data that is typically publicly available.

From the tool's definition Tool name contains 'scrape' and description states 'retrieve...recent news articles...from multiple sources' with no mention of data modification, deletion, or execution of arbitrary operations.

POLICY

How to control scrape_stock_news

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 scrape_stock_news:

policy.json

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

scrape_stock_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 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.
