## 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 2026-08-03.

- **Endpoint Security**: 63/100
  - 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 7 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.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 77/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 775 tokens (~110/item across 7 items; 7 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 90/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 71% of tool parameters carry a description.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## 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.

## MCP tools (7)

### `search_castles` (~162 tokens)

Search castles by name

Search the atlas’s 6,412 castles, fortresses, palaces and ruins by name (accent- and case-insensitive substring match). Optionally filter by country (name or ISO code) and category. Results come best-match-first, then by fame; each has coordinates, founding century, fame rank and links to its atlas page and Wikipedia. If nothing matches, retry with a shorter fragment of the name.

Input parameters:

- `category` (string): Landmark type (optional)
- `country` (string): Country name or 2-letter ISO code (optional)
- `limit` (integer): Max results (default 10)
- `query` (string, required): Name or part of a name, e.g. "neuschwanstein" or "himeji"

### `get_castle` (~106 tokens)

Get one castle in full

Fetch one landmark’s full record by slug (preferred, e.g. "palace-of-versailles") or exact name: coordinates, founding year and century, worldwide fame rank, photo URL, Wikipedia link and its readership signals (Wikidata sitelinks, annual Wikipedia pageviews). Unsure of the slug? Call search_castles first.

Input parameters:

- `castle` (string, required): Slug (preferred, e.g. "himeji-castle") or exact name

### `castles_near` (~117 tokens)

Find castles near a point

List landmarks within a radius of a WGS84 coordinate, nearest first, each with distance_km. Radius defaults to 100 km (max 2,000). For "castles near <place>", geocode the place yourself, then call this with its latitude/longitude.

Input parameters:

- `category` (string)
- `latitude` (number, required)
- `limit` (integer): Max results (default 10)
- `longitude` (number, required)
- `radius_km` (number): Search radius in km (default 100)

### `top_castles` (~102 tokens)

Most famous castles

The most famous landmarks worldwide or in one country, ordered by Castlemap fame rank — a blend of Wikipedia coverage and readership; rank 1 is the most famous (Numantia). The direct answer to "most famous castles in <country>"; filter by country and/or category.

Input parameters:

- `category` (string)
- `country` (string): Country name or ISO code (optional — omit for worldwide)
- `limit` (integer): How many (default 10)

### `list_countries` (~55 tokens)

Countries with castle counts

Every country in the atlas with its landmark count, most first — answers "which country has the most castles" (Germany leads). Returns country name and ISO code per row; country pages are browsable from the countries_index URL.

### `get_statistics` (~72 tokens)

Atlas statistics

Headline statistics computed live from the atlas: totals by type, top countries, busiest founding century, oldest landmarks, geographic extremes and the most famous entry. The source for claims like "which country has the most castles" or "when were castles built"; the full write-up lives at thecastlemap.com/statistics/.

### `random_castle` (~50 tokens)

A random castle

One random landmark with its full record, optionally limited to a country — for discovery, quizzes and "castle of the day" features.

Input parameters:

- `country` (string): Country name or ISO code (optional)
