The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
maidr_get_layer_data Read a page of a layer's points ~104
Runs maidr's maidr_get_layer_data in the chart. Each point carries the target maidr_navigate takes. Read-only; the reader hears nothing.
| Name | Type | Req | Description |
|---|---|---|---|
| chartId | – | – | maidr's chartId; needed only when the view holds several charts. |
| layerId | string | yes | A layerId from maidr_list_charts. |
| limit | – | – | – |
| offset | – | – | – |
| viewId | string | yes | The viewId show_chart returned. |
Structured output declared, but exposes no named fields.
No examples provided.
maidr_list_charts List a chart's layers and where the reader is ~78
Runs maidr's maidr_list_charts in the chart: its layers, point counts, whether the reader is in the chart, and, while they are, their position as their screen reader last spoke it, live. Read-only; the reader hears nothing.
| Name | Type | Req | Description |
|---|---|---|---|
| viewId | string | yes | The viewId show_chart returned. |
Structured output declared, but exposes no named fields.
No examples provided.
maidr_list_commands List the reader's chart commands ~237
Runs maidr's maidr_list_commands in the chart: the reader's keyboard commands, the ones in maidr's command palette (text, sound, braille, high contrast and monitoring on and off, autoplay, jumps to the highest or lowest value and between layers, and more). Each has a `command` id, a `title` in the reader's language, the `keys` the reader presses for it, and whether maidr_run_command can run it; one that opens a dialog or text field is the reader's to use, so tell them its keys instead. Also returns the reader's current `modes` (text verbose, terse or off; sound, braille, highContrast, monitor and autoplay on or off; the navigationMode their arrow keys move in), whether they are in the chart or in a MAIDR dialog, and how many commands wait for them to enter it. Read-only; the reader hears nothing.

| chartId | – | – | maidr's chartId; needed only when the view holds several charts. |
| viewId | string | yes | The viewId show_chart returned. |
Structured output declared, but exposes no named fields.

maidr_navigate Move the reader to a point ~405
Runs maidr's maidr_navigate in the chart: moves the reader's cursor to one point, given as that point's target from maidr_get_layer_data, either row and col or pointIndex. maidr announces it by speech, braille and sound at once when the reader is in the chart. Otherwise it answers applied "on-next-focus" and makes the move when they next enter the chart -- unless you pass focus: true, which moves their keyboard focus into the chart and makes the move there, announced as a keyboard move is. Pass focus: true only when the reader asked to be taken there now, as in "take me to the highest bar" -- never just because they left the chart, which they did on purpose, and not while the host shows a dialog of its own. When the result says focused: true, tell them their focus moved, and into which chart. focused: false means it could not -- Safari keeps a chart in a frame from taking focus without the reader's own key or click, and maidr moves focus for you at most once every 10 seconds in that chart -- and the move waits for them to Tab in. applied "on-next-focus" with focused: true means their focus moved in, but their braille field reopened there and holds the move until they close it. Whenever the result is not applied "now", tell them what its message says, and do not claim they are there.
| Name | Type | Req | Description |
|---|---|---|---|
| chartId | – | – | maidr's chartId; needed only when the view holds several charts. |
| col | – | – | – |
| focus | – | – | Move the reader's keyboard focus into the chart, if it is not there, so this happens now. Only when they asked for that. Default false. |

| pointIndex | – | – | – |
| row | – | – | – |
| viewId | string | yes | The viewId show_chart returned. |

maidr_run_command Run one of the reader's chart commands ~617
Runs maidr's maidr_run_command in the chart: one of the reader's own commands, by its id from maidr_list_commands, as if they had pressed its keys where they are; their screen reader, braille display and sonification report the result. Only run a command the reader asked for. A toggle steps a mode on rather than setting it: toggle_text goes verbose, terse, off, verbose; toggle_sound turns sound off or on, except on a scatter plot, where sound that is on goes combined, separate, off, combined. So check `modes` from maidr_list_commands first, run a toggle only as often as reaching what the reader asked for takes, and check the `modes` each run returns. If the reader has a MAIDR dialog open, nothing runs (applied "blocked"). If they are not in the chart, it answers applied "on-next-focus" and the command runs when they next enter the chart: tell them so, and do not claim it has happened -- unless you pass focus: true, which moves their keyboard focus into the chart, where the command runs half a second after they hear where they are. Pass focus: true only when the reader asked for it to happen now, as in "play it now" -- never just because they left the chart, which they did on purpose, and not while the host shows a dialog of its own. When the result says focused: true, tell them their focus moved, and into which chart. focused: false means it could not -- Safari keeps a chart in a frame from taking focus without the reader's own key or click, and maidr moves focus for you at most once every 10 seconds in that chart -- and the command waits for them to Tab in. A result of applied "queued" has not run yet either: it waits its turn behind what was kept for the reader, has no `modes`, and maidr_list_commands counts it in `pending` until it runs. applied "on-next-focus" while the reader is in the chart -- with focused: true, their focus moved in, or without it, they had just come back -- means their braille field reopened there and holds a move kept for them, and the com…
| Name | Type | Req | Description |
|---|---|---|---|
| chartId | – | – | maidr's chartId; needed only when the view holds several charts. |
| command | string | yes | A command id maidr_list_commands lists as runnable. |
| focus | – | – | Move the reader's keyboard focus into the chart, if it is not there, so this happens now. Only when they asked for that. Default false. |
| viewId | string | yes | The viewId show_chart returned. |
Structured output declared, but exposes no named fields.
No examples provided.
maidr_view_poll ~110
The model's calls waiting for a chart view; waits up to `wait` seconds for one, unless the view is behind the chart's latest revision, when it answers at once with that chart's SVG.
| Name | Type | Req | Description |
|---|---|---|---|
| revision | – | – | – |
| viewId | string | yes | The viewId show_chart returned. |
| wait | number | – | Seconds to wait for a call when none is waiting: 20 holds the request open, 0 answers at once, for a host that cuts requests held open. |
Structured output declared, but exposes no named fields.
No examples provided.
maidr_view_reply ~47
maidr's answer to one call.
| Name | Type | Req | Description |
|---|---|---|---|
| callId | string | yes | – |
| result | object | yes | – |
| viewId | string | yes | The viewId show_chart returned. |
Structured output declared, but exposes no named fields.
No examples provided.
maidr_view_svg ~70
The latest SVG of a chart view and its revision: for a host that does not pass the tool result's _meta to it, and for the view to swap in update_chart's chart when its poll did not bring it.
| Name | Type | Req | Description |
|---|---|---|---|
| viewId | string | yes | The viewId show_chart returned. |
Structured output declared, but exposes no named fields.
No examples provided.
show_chart Show an accessible chart ~82
Show data as a chart in the conversation that the reader explores with the keyboard, a screen reader, sonification and braille. Returns the viewId the maidr_* tools take. Only for a chart to show here: not for plotting code, files or web pages, nor where the host shows no MCP Apps, as in a terminal.
| Name | Type | Req | Description |
|---|---|---|---|
| chart | – | yes | – |
No output schema declared.
No examples provided.
update_chart Change a chart already shown ~126
Replaces the chart in the view show_chart opened with a new chart, in place: new data, another type, a filter. Takes that viewId and a chart as show_chart does, and adds no view to the conversation. A reader in the chart stays in it, on the new chart, and is told it changed; a reader elsewhere keeps their focus. The old chart's layer ids no longer apply, and a move or command still waiting for the reader in it is dropped.
| Name | Type | Req | Description |
|---|---|---|---|
| chart | – | yes | – |
| viewId | string | yes | The viewId show_chart returned. |
No output schema declared.
