First indexed and scored.

## MCP tools (3)

### `find_microchart` (~102 tokens)

Find a chart by question

Rank 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.

Input parameters:

- `dataShape` (string): Optional filter, e.g. "number[]".
- `limit` (integer): Max results (default 6).
- `question` (string, required): What the data needs to show, in plain language.

Output parameters:

- `results` (array)

### `get_microchart` (~77 tokens)

Get a chart's props + example

Full 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.

Input parameters:

- `slug` (string, required): Chart slug, e.g. "sparkline".

Output parameters:

- `avoidFor` (array)
- `bestFor` (array)
- `dataShape` (string)
- `encoding` (object)
- `example` (object)
- `interactiveImport` (string)
- `name` (string)
- `props` (array)
- `sample` (object): Ready-to-render props — pass straight to render_microchart.
- `sharedProps` (array)
- `slug` (string)
- `staticImport` (string)
- `status` (string)
- `tagline` (string)

### `render_microchart` (~154 tokens)

Render a chart to SVG

Render 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.

Input parameters:

- `data`: Primary series (array), or a keyed object for charts that take one; omit for scalar charts.
- `format` (string): `svg` (default) or `bare`.
- `props` (object): Other props (value, target, color, …).
- `type` (string, required): Chart slug, e.g. "sparkline".

Output parameters:

- `height` (number)
- `library` (string)
- `mimeType` (string)
- `summary` (string): The chart's generated accessible name — its alt text.
- `svg` (string)
- `width` (number)
