Slickfast MCP server

SlickFast

A deterministic render engine. Spec in, same bytes out. Forever. Charts, boards, and whole Pages. No headless browser.

↑ Engine output — one JSON spec, one image. Get this exact board on your README with the dashboard template (teal-hero layout).

Local MCP is free forever. A public URL is a plan (free key is enough to learn).

The spec is the chart. A pagespec is a Page. Add .json — that’s the twin. The hash is on the page. Don’t trust us. Check the math.

This project's pulse — a LIVE chart, right here in the README

The dashboard below is not a screenshot. It's a SlickFast live chart: a permanent image URL whose numbers update on their own. A scheduled job pushes fresh stats; every visitor sees current data. Live Charts — embed once, update forever.

The range — two boards, two renders

A seller ops board (funnel, bullet graph, goal ring, gauge, calendar heatmap, leaderboard — demo data):

And the board that explains the engine — it times its own render into its title:

Prove it yourself

Don't take the speed or determinism claims on faith — run the benchmark on your own machine:

git clone https://github.com/SlickFast/slickfast && cd slickfast
node scripts/bench.mjs

It renders all 47 chart types, times each, runs a 10,000-chart throughput burst, and double-renders everything to verify byte-identical output. On an M1 Max: median 15µs per chart, ~140,000 renders/sec, 47/47 deterministic. Your numbers are your numbers.

Quick start (MCP)

One-click:

Add to your MCP client config (Claude Code, Claude Desktop, Cursor, …):

{
  "mcpServers": {
    "slickfast": {
      "command": "npx",
      "args": ["-y", "@slickfast/mcp"],
      "env": { "SLICKFAST_API_KEY": "SF-…" }
    }
  }
}

Omit env to stay local-only (draw free forever). Add a free key from slickfast.com when you want a live URL, share, or a published Page.

Then: getstarted → news → gallery → one renderchart. Full tool docs: apps/mcp/README.md.
