Get a download URL for an icon with custom color and size options. Supports SVG and PNG formats. Note: Free API access is limited to public domain icons only.
AI agents call get_download_url to retrieve information from Noun Project MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and returns a download URL—a read-only data retrieval operation with no side effects. Even though a user *could* subsequently download content from that URL, the tool itself performs no destructive, financial, or execution-based action. The blast radius of misuse is minimal: an attacker gains access to publicly available icon download URLs, which pose no security or data integrity risk.
From the tool's definition The tool 'retrieves' a 'download URL' for icons with 'custom color and size options', supporting 'SVG and PNG formats'. The description explicitly states it 'Get[s]' a URL, which is a query/retrieval operation.
