Search Cosmetic Adverse Event Reports (CAERS).
AI agents call search_cosmetic_events to retrieve information from OpenFDA FastMCP Server 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 data from FDA's public CAERS database without performing any write, delete, or execute operations. The blast radius of misuse is minimal—the worst outcome would be inappropriate queries returning public health data already published by the FDA. No financial, destructive, or irreversible actions are possible.
From the tool's definition Tool name 'search_cosmetic_events' and description 'Search Cosmetic Adverse Event Reports (CAERS)' indicate a query/search operation over public FDA adverse event data with no modification or deletion capability.

"default": "deny",
"tools": {
"search_cosmetic_events": {}
}
