Search for icons from lucide by name or category using partial matching
AI agents call search_icons to retrieve information from Lucide Icons MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only search function that retrieves icon data without any side effects. It matches the 'Read' category pattern of searching and retrieving data. The severity is low because the tool has no ability to modify, delete, or execute operations; misuse would at worst return unwanted icon metadata.
From the tool's definition Tool description states it 'Search for icons from lucide by name or category using partial matching' — this is a query/search operation with no modification, deletion, or execution of code.

"default": "deny",
"tools": {
"search_icons": {}
}
}search_icons is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
