From the tool's definition Tool name 'search_news' and description 'Searches for specific crypto news' indicate a query operation that retrieves data without modifying or executing transactions.

POLICY

How to control search_news

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

policy.json

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

search_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 Crypto Multi-MCP Hub — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
