Streamline

447,000+ icons in 34 families, plus illustrations, with an API and an MCP server

Tier A · StrongIcon SetAsset PackMarketplacestreamlinehq.com

Streamline is a commercial icon and illustration catalogue of about 447,000 assets organised into 34 families and 172 sets, spanning its own styles (Ultimate, Core, Flex, Sharp, Plump, Micro, Freehand, Nova, Cyber, Vault) and mirrored open-source sets such as Lucide, Phosphor, Tabler, Feather, Carbon and Material Symbols. Beyond the web app it ships a Figma plugin, VS Code, Webflow, Framer, Miro and Lucid plugins, a REST API and an MCP server. Access is subscription or one-time lifetime purchase per set, with roughly 9,000 free assets at /freebies.

For an agent

This is the one paid icon catalogue with an MCP server, so if the user already has a Streamline subscription, wire the MCP up and search assets in-conversation instead of scraping the site. Without a subscription, treat it as reference only and fall back to Lucide or Iconoir — the free freebies tier is small and the per-project caps (100 icons, 50 illustrations) bite on anything real. Also note that plain curl hits a Vercel Security Checkpoint on streamlinehq.com, so headless scraping of the catalogue will fail.

Why it is here. The largest coherent commercial icon system, and the only one that has shipped an MCP server so an agent can search it directly.
