Tools & capabilities

Microcharts tools 3

  • find_microchartRank microcharts chart types against a plain-language question about data ("is it trending?", "error budget", "part to whole"). Returns candidates with the reason each matched. Start here when you know the question, not the chart.
  • get_microchartFull wiring detail for one chart by slug: import paths, its props plus the shared props, data shape, best/avoid guidance, a copy-runnable example, and `sample` — the example as JSON props you can pass straight to render_microchart.
  • render_microchartRender a chart to a finished, self-contained SVG (styles embedded) plus its generated alt text — for surfaces that can't run React. Pass the series as `data`; put other props (value, target, curve, color, width) in `props`. Each chart takes its own data shape — get_microchart returns a valid `sample` to adapt.

X402 Dataviz MCP tools 1

  • render_chartRender a bar, line, or area chart from structured data and return it as an SVG string. Free, unauthenticated MCP tool — the open twin of the paid x402-gated dataviz HTTP API (https://x402-dataviz-poc.theliminalguy.workers.dev/chart), same renderer, no payment required.
