AI agents call get_drug_warnings_by_name to retrieve information from OrigeneMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only lookup of drug safety warnings from a database. It retrieves pre-existing warning information for drugs without creating, modifying, deleting, or executing any operations. The verb 'retrieve' and the informational nature of drug warnings (reference data) clearly place this in the Read category.
From the tool's definition Tool name 'get_drug_warnings_by_name' and description 'Retrieve warnings for a specific drug' indicate a query operation that retrieves existing safety information without modifying data or triggering external actions.

PolicyLayer is an MCP gateway — it sits between your AI agents and OrigeneMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_drug_warnings_by_name:
{
"version": "1",
"default": "deny",
"tools": {
"get_drug_warnings_by_name": {}
}
