ApexCharts

Build a minimal valid ApexCharts options object for a given chart type. Picks the correct series data format (axis vs non-axis) and supplies placeholder data when none is given. Use this as the starting point for a chart. Since apexcharts 8.0 the Tier 2 types (waterfall, dumbbell, streamgraph, raincloud, violin, icicle, sunburst, unit, waffle) are outside the default bundle: the page also needs that type's add-on import next to 'apexcharts', or `import ApexCharts from 'apexcharts/full'`; apexcharts_list_types names the import per type.

Build a minimal valid ApexGantt options object. Generates a placeholder schedule (phases, dependencies, a milestone) when `tasks` is omitted, so the result can be rendered as-is. The placeholder dates are emitted in whatever `inputDateFormat` is chosen, so they parse without further work.

Build a minimal valid `<apex-grid>` config: `{ columns, data }`. When both are omitted, a small users table is generated. When only `columns` is omitted, they are inferred from the keys of the first data row with `type` inferred per column. Pass `enableSortAndFilter: true` to opt every generated column in.

Build a minimal valid ApexMaps options object for a geographic visualization. Supports the six series types: choropleth (default), bubble, marker, arc, line, hexbin. Geometry comes from the built-in registry (e.g. "world/countries", "us", "eu/nuts2"), so no GeoJSON is needed. Generates a small placeholder dataset when data is omitted. Use the result with `new ApexMaps(el, options)` then `await map.render()`.

Build a minimal valid ApexSankey config split into `options` (constructor) and `data` (render payload). Generates a 5-node placeholder flow when nodes/edges are omitted so the result renders something visible. Use the result by calling `new ApexSankey(el, options)` then `sankey.render(data)`.

Build a minimal valid ApexStock options object for a financial / stock chart. Generates a placeholder OHLCV candle series when `data` is omitted, so the result renders as-is. Note: ApexStock does not bundle ApexCharts. The host provides the constructor per instance (`new ApexStock(el, options, { ApexCharts })`), once app-wide (`ApexStock.setApexCharts(ApexCharts)`), or as the `window.ApexCharts` global. That is a host-page concern, not part of this options object.

Build a minimal valid ApexTree config split into `options` (constructor) and `data` (the root NestedNode passed to `tree.render(data)`). Generates a small 3-level org chart placeholder when `data` is omitted. Every node in the output has `children: []` even for leaves (ApexTree requires it).

Read authoritative ApexCharts documentation from the bundled apexcharts-skill knowledge base. Call with no arguments to list all available files (SKILL.md plus per-family reference docs). Call with `file` to return that file as markdown. Use this when you need to look up an option, formatter signature, plotOptions detail, or a fully worked example for a specific chart family.

Return every product (charts, gantt, tree, sankey, grid, stock, maps) currently exposed by this MCP server, with a "when to pick this" hint and the tool names it registers. Use this once at the start of a session to decide which product matches the user's task; then call that product's tools directly. Each product also reports `compatibility`: the bundled skill version and the upstream library version its guidance was verified against; use it to tell the user which library version this server targets. Results respect the APEXCHARTS_MCP_PRODUCTS env-var gating.

Return every ApexCharts chart type this server supports, with name, description, family (cartesian/bar/financial/circular/grid/radar/unit), series format (axis vs non-axis), expected data shape, the reference doc filename for deeper detail, and `bundle`: { tier: 1 } for a type the default bundle has, or for a Tier 2 type { tier: 2, import, scripts, since, failure, note? } naming the add-on it needs. Optionally filter by family.

Check an ApexCharts options object against the data-format rules and known pitfalls (wrong series shape for chart type, radialBar values outside the min/max domain, undefined data points, conflicting tooltip flags, hex colors missing #, etc.). Returns structured issues so the caller can fix them. Returns ok: true when there are no errors (warnings still allowed).

Read authoritative ApexGantt documentation from the bundled apexgantt-skill knowledge base. Call with no arguments to list all available files. Call with `file` to return that file as markdown. Use this to look up task data format, dependency types, view modes, the update lifecycle, or framework integration.

Check an ApexGantt options object against what the library does with it (missing id/name, tasks missing the dates the library requires, an incomplete `parsing` map, duplicate ids, orphan parentId, progress out of 0 to 100, ISO dates with the default MM-DD-YYYY format, dependency object using `id` instead of `taskId`, unknown dependency target, self-dependency, invalid dependency type, cycles, baseline missing start/end). Returns structured issues with stable rule ids.

Read authoritative apex-grid documentation from the bundled apexgrid-skill knowledge base. Call with no arguments to list available files; call with `file` to fetch markdown. Use this for ColumnConfiguration, Lit cellTemplate, sort/filter, data pipeline, or framework integration.

Check an apex-grid `{ columns, data }` config against apexgrid-skill rules: columns/data required and array-shaped, every column.key must be a real key of the data rows, column.key unique, type is one of apex-grid's column types (string, number, boolean, date, currency, select and the other presentation types), sort/filter is boolean or config object. Returns structured issues with stable rule ids.

Read authoritative ApexMaps documentation from the bundled apexmaps-skill knowledge base. Call with no arguments to list available files; call with `file` to fetch markdown. Use this for series datum shapes, joins, the geometry registry, projections, scales, drilldown, theming, or framework integration.

Check an ApexMaps options object against what the library does with it: geo.map present and a built-in map id (or a URL / inline geometry), hex layouts only where one exists, a frameable geo.view.fit, known series types, arc from/to endpoints, line paths, bubble/marker coordinates or something to join on, hexbin point positions and aggregates (a hexbin has no joinBy), [lon, lat] ordering, joinBy shape, null (not undefined) for missing values, and known scale / projection / palette names. Returns structured issues with stable rule ids, severity, path, and a fix when there is a one-shot remedy.

Read authoritative ApexSankey documentation from the bundled apexsankey-skill knowledge base. Call with no arguments to list available files; call with `file` to fetch markdown. Use this for the { nodes, edges, options } data shape, layer ordering, styling, or framework integration.

Check an ApexSankey config against what the library does with it (unique node ids, edges reference real nodes, no negative values, no self-loops, no parallel edges that collapse into one, nodes without edges). Cycles are allowed: they render as dashed loops. Accepts the wrapped `{ options, data }` shape from generate_config, the raw render payload `{ nodes, edges }`, or an ApexSankey.compare `{ before, after }` config.

Read authoritative ApexStock documentation from the bundled apexstock-skill knowledge base. Call with no arguments to list all available files. Call with `file` to return that file as markdown. Use this to look up the OHLC data format, indicators, streaming/appendData, trading overlays, theming, or framework integration.

Check an ApexStock options object against the rules in apexstock-skill (missing series/data, flat o/h/l/c keys instead of a y:[o,h,l,c] array, malformed or inconsistent OHLC tuples, missing/invalid x, non-ascending data, invalid theme.mode, and unknown indicator keys). Returns structured issues with stable rule ids.

Read authoritative ApexTree documentation from the bundled apextree-skill knowledge base. Call with no arguments to list available files; call with `file` to fetch markdown. Use this for the NestedNode data shape, grow directions, nodeTemplate, the graph API, or framework integration.

Check an ApexTree config against what the library does with it: root is a NestedNode, every node has an id and a label, children (when present) is an array, ids unique across the whole tree, valid direction/edgeStyle/edgeColorMode/theme values, enableSelection is "single"|"multi"|false (NOT boolean true), and a warning when contentKey is "data" but a node has no `data` payload. Accepts both the wrapped `{ options, data }` shape and a bare root node.
