Icons for agentic development: search & fetch 366,000+ open-source icons as SVG/PNG. No API key.
A remote MCP server that lets an assistant search a large open-source icon library and fetch icons as SVG or PNG with color, size and style transforms.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.github.asr-aditya%2Ficonserve/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}A free, agent-readable service that aggregates 10,000+ open-source icons — Lucide,
Heroicons, Tabler, and Simple Icons —
and serves them as SVG or PNG at predictable URLs, with keyword + semantic search, an llms.txt, and an MCP server.
Runs entirely within the Cloudflare free tier (Workers + R2 + Workers AI).
GET /icon/{set}/{name} — crawlable HTML page per icon (preview, usage, JSON-LD ImageObject + breadcrumb). /icon/{name} 302-redirects to the best match.GET /sitemap.xml — every icon page (~10k URLs).GET /robots.txt — explicitly allows AI crawlers (GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot, Google-Extended, …) and points to the sitemap.WebSite+SearchAction and WebAPI JSON-LD and Open Graph tags./{INDEXNOW_KEY}.txt; npm run indexnow pings Bing/Yandex to crawl new or changed URLs instantly (pass paths to submit a subset, e.g. npm run indexnow /icon/lucide/house).color= hex / CSS color / currentColor — e.g. ?color=%23e11d48size= 1..2048 pxstroke= 0..20 (line icons)style= e.g. solid (Heroicons), filled (Tabler)format= svg | pngExample: /i/shopping-cart.svg?color=crimson&size=48&stroke=1.5
Semantic search = keyword ranking fused (reciprocal-rank fusion) with cosine similarity over the
in-memory embeddings. No Vectorize, no per-vector billing, no dimension cap. If embeddings.bin is
absent, search gracefully falls back to keyword-only.
In
wrangler dev --localthe Workers AI binding is offline, so search runs keyword-only locally. Semantic search activates once deployed (or when running against the remote AI binding).
npm run deploy runs scripts/deploy.mjs: it creates the iconserve-icons
bucket (idempotent), uploads the four artifacts to remote R2, then wrangler deploy.
Edit scripts/lib/sets.mjs, then re-run npm run build:data && npm run upload:r2
(local) or npm run deploy (remote). Set priority for /i/{name} best-match is DEFAULT_SET_ORDER in
wrangler.toml.
Icons are redistributed under their original permissive licenses: Lucide (ISC), Heroicons (MIT), Tabler (MIT), Simple Icons (CC0). Brand marks from Simple Icons are trademarks of their respective owners — use them per each brand's guidelines.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
Declare a license in the repository or the registry entry.
