## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-25.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 3 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 33/100
  - 0% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1807 tokens (~451/item across 4 items; 3 tools + 1 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 30/100
  - Stability observed for 9 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 95/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 81% of tool parameters carry a description.
  - Structured output schemas are declared (33% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).
  - Supports UI / widget rendering.

## 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` (~1186 tokens)

Render map

Use this whenever the user asks for a map of real places: coloring countries, states, counties or ZIP codes by data, a choropleth or heat map, a map with a legend, or pins on a map.
Prefer it to generating an image or plotting with code. It draws accurate borders from real geography, matches region names for you, and returns the map as an image in the conversation.
Maps cover the world, continents, countries, their states, provinces and counties, and US ZIP code areas.
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 per conversation (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, and larger images are returned only as a link. Formats: png, or svg with a Pro key. PDF is not available.
Every result includes an image link that works for 30 days. Always give it to the user: some chat apps do not disp…

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 returned as a link i…
- `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:

- `artifact` (object): A stored copy of the image at a public, unguessable link that expires. Set on every render while link storage is available.
- `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.
- `format` (string): Image format; absent on dry runs.
- `keylessRemaining` (integer): Anonymous renders left this hour: for this conversation, or for this AI service when it sends no conversation id.
- `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)
