## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-09-25 (score 72, 0)

- [functional] We updated how we score, so this day's move reflects our rubric, not a change to the server

### 2026-09-24 (score 72, +1)

No change was recorded against any check on this day. Stability & Change Management went from 27 to 30. That category is still filling its 30-day observation window: 8 days of observed history at the previous scan, 9 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-09-23 (score 71, +4)

## MCP tools (3)

### `list_maps` (~265 tokens)

List maps

List the maps Ultimaps can render: the world, continents, countries subdivided into states, provinces, counties or departments, and US ZIP code areas.
Each row is {id, title, regionType, layers, regionCount, labels}. `id` is the mapId for render_map and get_map_regions; it is the map's slug on ultimaps.com (the last path segment, not the whole URL) and always means the current edition.
\`regionCount` is how many region keys a complete dataset needs. `labels: false` means the map has no region labels, so `style.labels` does nothing there. `layers` are the ids render_map's `layers` can turn on.
Pass `query` to search ids, titles, region types and categories (e.g. "counties", "germany", "africa").
Only call this when you don't know the id: common ids such as `world`, `united-states` and `europe` just work, and an unknown id usually comes back with the closest ids.

Input parameters:

- `query` (string): Search map ids, titles, region types and categories, e.g. "counties", "germany", "africa". Omit to list every map.

### `get_map_regions` (~227 tokens)

Get map regions

Look up one map: title, regionType, regionCount, labels, layers, and its regions as {key, title}, 200 per page.
You rarely need this before rendering. render_map accepts region names, codes and common aliases and auto-corrects typos, reporting what it matched.
Use it to build a dataset covering every region of a map, to see how a map names its regions, or to resolve a key render_map could not match.
\`query` searches keys, titles and aliases, so no hits means the map really has no such region. Use `offset` for further pages.

Input parameters:

- `mapId` (string, required): Map id from list_maps, e.g. "united-states", "europe", "united-states-california".
- `offset` (integer): Skip this many regions. Pages hold 200 regions; use the offset the previous result names.
- `query` (string): Search region keys, titles and aliases, e.g. "saint" or "US-TX". Omit to page through every region.

### `render_map` (~1135 tokens)

Render map

Render a map of the world, a continent, a country, its states/provinces/counties, or US ZIP code areas as an image shown in the conversation.
Color regions with ONE of these (choropleth and categories are mutually exclusive):
\- `choropleth`: a number per region, e.g. {"values": {"California": 39.5, "Texas": 30.5}}. Classes, breaks and palette are picked from the data unless you set them.
\- `categories`: a label per region, e.g. {"values": {"France": "Euro", "Poland": "Złoty"}}. Colors are assigned automatically unless you set `colors`.
\- `regions`: explicit hex colors, e.g. {"Texas": "#1D4ED8"}. Also works on top of either mode as an override.
Region keys can be names, ISO/FIPS-style codes or common aliases. Typos are auto-corrected, and every correction or unmatched key is reported with suggestions, so there is no need to call get_map_regions first. Get `mapId` from list_maps if you don't know it.
Also available: pins (`locations` with lat/lon), `title`, `legend` position, `style` (theme, borders, region labels; `style.labels.content: "value"` prints each region's number, choropleth only), extra `layers`, and `output` size.
\`dryRun: true` validates and previews region matching and the color plan without rendering.
Without an API key: 30 renders per hour and 5 per minute (dry runs count), PNG up to 1600 px wide, with Ultimaps attribution on the image. The default 1200 px width is right for viewing in chat. Larger widths and scales are for files and are saved to disk instead of shown. Formats: png, or svg with a Pro key. PDF is not available.
Every render is also written to a file and the path reported. Relay that path: in a terminal client the inline image is visible to you but NOT to the user, and the file is the only thing they can open.
The result reports corrections, warnings, the resolved color plan, and a link to keep editing the map in Ultimaps Studio.

Input parameters:

- `categories` (object): Categorical coloring mode. Mutually exclusive with `choropleth`. Unmatched keys simply leave their regions uncolored. The no-data fill is `style.defaultRegionColor`, and `noDataColor` does not apply…
- `choropleth` (object): Numeric choropleth mode. Mutually exclusive with `categories` (one scale per map). `regions` composes with it as an override layer. If none of the keys in `values` match, the request fails even under…
- `dryRun` (boolean): Validate and preview without rendering: returns the region matching report, the resolved choropleth plan and a legend preview. No image and no monthly quota for keyed calls, but it still counts again…
- `layers` (object): Extra geographic layers to draw, e.g. {"cities": true, "roads": true}. Each map ships a subset (`layers` in list_maps and get_map_regions). Turning on a layer the map lacks is not an error: it is ski…
- `legend` (object)
- `locations` (array): Pin markers. They compose with every mode.
- `mapId` (string, required): Map id from list_maps, e.g. `world`, `united-states`, `europe`, `united-states-california`. It is the map's slug on ultimaps.com (the last path segment, not the whole URL) and always resolves to the…
- `onUnmatched` (string): warn = render anyway (unmatched regions get the no-data fill) and report. error = 400 with per-key suggestions. Recommended for production pipelines: error. Exception: in choropleth mode, ZERO matche…
- `output` (object): Image size and format. Keep the default width (1200 px) for images viewed in the conversation: much larger renders, and any scale of 2 or more, are too big to show inline and are saved to a file inst…
- `regions` (object): Override layer. Region key to hex color, applied AFTER choropleth/categories coloring and winning over it. Precedence: choropleth/categories paint first, `regions` overrides win, and everything else…
- `style` (object)
- `title` (object)

Output parameters:

- `choropleth` (object): The resolved choropleth plan. Dry runs add `reason` and `breaks`.
- `dryRun` (boolean)
- `editUrl` (string): Opens this map in Ultimaps Studio for editing or export.
- `embedUrl` (string): Keyless GET image URL, when the render is shareable that way.
- `file` (object): Set when the image was saved to disk (too large to inline, or SVG).
- `format` (string): Image format; absent on dry runs.
- `keylessRemaining` (integer): Keyless renders left in the current hour.
- `legend`: Dry runs: legend preview, [{label, color}] or {points, stops} for a gradient.
- `matchingTruncated` (boolean): True when `corrected`/`unmatched` list only the first 5 of their counts. Repeat the call with dryRun: true for the full report.
- `regionMatching` (object)
- `renderId` (string|null): The API render id; quote it to Ultimaps support.
- `warnings` (array)

## Common questions

### What is the Ultimaps MCP server?

Ultimaps is an MCP server listed in the public MCP registry as com.ultimaps/mcp. Create choropleth, category and pin maps of countries, states, counties and ZIP codes as images. This page covers its npm package (@ultimaps/mcp).

### Is the Ultimaps MCP server safe to use?

Ultimaps scores 72 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 25 September 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Ultimaps MCP server expose?

Ultimaps exposes 3 tools: list_maps, get_map_regions, render_map. Their descriptions and schemas cost roughly 1,627 tokens of context every time the server is loaded.

### Is the Ultimaps MCP server still maintained?

Ultimaps is still listed as active in the MCP registry. We last reached this channel on 25 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Ultimaps MCP server under?

Ultimaps declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
