Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

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 →
add_layers Add layers to a map ~240
Add markers, routes, proportional circles, pattern fills, annotations or labels to an existing map, and return the new URL. Takes the svg_url of a map you already made. Everything on it is kept — this appends rather than replaces, so it is also how you build a map up over several turns. Resolve coordinates with find_places before adding a marker. Guessed lat/lon lands in the wrong country and the render will not complain. Use sea routes for shipping: they follow the lanes through Suez, Panama and Malacca instead of drawing a straight line over land.
| Name | Type | Req | Description |
|---|---|---|---|
| annotations | array | – | Per-region tooltip text. |
| labels | – | – | "ISO" labels every large region; an array labels only those ids. |
| map | string | yes | A map URL from a previous call. Everything already on it is kept. |
| markers | array | – | Points to add. |
| patterns | array | – | Per-region texture fills, for hatching a category onto a choropleth. |
| proportional | array | – | Circles at region centroids, area proportional to value. |
| routes | array | – | A→B lines to add. |
| Name | Type | Req | Description |
|---|---|---|---|
| editor_url | string | yes | – |
| embed | string | yes | – |
| png_url | string | yes | – |
| svg_url | string | yes | – |
| warnings | array | yes | – |
No examples provided.
create_map Create a map ~753
Make a production-ready static map and return its URL plus a rendered preview. The map is a URL: the returned svg_url renders the same image forever, embeds in an <img> tag with no JavaScript, and is the handle the other maproll tools accept. Use it for choropleths (numeric values per region), flat colour paints, qualitative category maps, and plain highlight maps. Region ids are ISO 3166-1 alpha-2 at the "world" scope ("US", "DE", "BR") and ISO 3166-2 inside a country scope ("RO-B", "RO-CJ"). Numeric values and text categories cannot appear in the same map — pick one. Do not use it for interactive or zoomable maps, driving directions, or street-level detail; maproll renders static statistical maps, not a slippy map.
| Name | Type | Req | Description |
|---|---|---|---|
| attribution | boolean | – | OpenStreetMap credit. On by default and should stay on. |
| bbox | string | – | Crop to "minLon,minLat,maxLon,maxLat"; the projection refits to the rectangle. |
| breaks | array | – | Bin upper bounds. Required when classification is custom. |
| classification | string | – | How numeric values are binned. Ignored for diverging and categorical scales. |
| colorScale | string | – | Sequential for magnitudes, diverging for values around a midpoint, categorical for buckets. |
| extra | object | – | Escape hatch for documented parameters without a field here (patterns, annotations, proportional, labelMinArea, ...). Passed through verbatim. |
| graticule | boolean | – | Draw a 10-degree lat/lon grid. |
| height | integer | – | Pixel height. Defaults to the projection's aspect ratio. |
| highlight | array | – | Region ids to highlight with no data behind them. Use instead of `values` when the point is which regions, not how much. |
| labels | – | – | "ISO" labels every region above the size threshold; an array labels only those ids. |
| legend | boolean | – | Show the legend. Defaults true; set false for flat colour paints, which have no scale to show. |
| legendLayout | string | – | – |
| legendNoData | string | – | Label for an extra legend swatch, in the map's land colour, covering the regions with no value — so a reader can tell the lowest band from absent data. Pass the label itself, and make it say what bla… |
| legendTitle | string | – | Caption above the legend. |
| northArrow | boolean | – | Compass arrow, top right. |
| projection | string | – | Map projection. Each scope has a sensible default; override only with a reason. |
| scaleBar | boolean | – | Kilometre scale bar, bottom left. |
| scope | string | yes | Geography to draw. "world", a group ("EU", "NATO", "G20", "ASEAN", "AFRICA"), or a country code for its subnational regions ("RO"). Read maproll://catalog/scopes for the full list. |
| subtitle | string | – | Smaller line under the title. |
| theme | string | – | Colour theme. Defaults to dark. |
| title | string | – | Headline above the map. |
| values | array | – | Per-region data. Give `value` for a choropleth, `color` to paint a region flat, or `category` for qualitative buckets. |
| width | integer | – | Pixel width. Defaults to 1200. |
| Name | Type | Req | Description |
|---|---|---|---|
| editor_url | string | yes | Open in the maproll editor. |
| embed | string | yes | Ready-to-paste <img> tag. |
| png_url | string | yes | Same map as PNG. |
| svg_url | string | yes | Embeddable SVG. This is also the handle other tools take. |
| warnings | array | yes | Non-fatal problems, e.g. region ids the renderer did not recognise. |
No examples provided.
describe_options List what the renderer accepts ~88
Return the exact accepted values for scopes, themes, marker icons, projections, pattern fills, or the URL grammar. The same content is published as the maproll:// resources; this tool is for hosts that do not read resources. Check it rather than guessing a name — an icon or theme that does not exist renders nothing and reports no error.
| Name | Type | Req | Description |
|---|---|---|---|
| kind | string | yes | Which catalog to return. |
No output schema declared.
No examples provided.
find_places Find a place ~153
Resolve a place name to real coordinates and the region id maproll uses. Searches countries, regions, cities and airports, and returns each hit's ISO 3166-1 / 3166-2 / IATA code alongside its latitude and longitude. Use it before placing any marker or lat,lon route endpoint. Coordinates recalled from memory are frequently wrong by degrees, and a map renders a wrong marker exactly as confidently as a right one.
| Name | Type | Req | Description |
|---|---|---|---|
| kind | string | – | Narrow the search. Omit to search all four. |
| limit | integer | – | Default 10. |
| query | string | yes | Place name to resolve, e.g. "Constanța", "Suez", "Heathrow". |
| Name | Type | Req | Description |
|---|---|---|---|
| places | array | yes | – |
No examples provided.
