Available components
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. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- 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. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability78
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 793 tokens (~113/item across 7 items; 7 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage90
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 71% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail
How do I install the com.thecastlemap/castles MCP server?
com.thecastlemap/castles is a hosted endpoint at https://thecastlemap.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

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 →
castles_near Find castles near a point ~117
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.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | – |
| latitude | number | yes | – |
| limit | integer | – | Max results (default 10) |
| longitude | number | yes | – |
| radius_km | number | – | Search radius in km (default 100) |

No examples provided.
get_castle Get one castle in full ~122
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 with photographer credit and licence, Wikipedia link and its readership signals (Wikidata sitelinks, Wikipedia pageviews over the last 60 days summed across its largest language editions). Unsure of the slug? Call search_castles first.
| Name | Type | Req | Description |
|---|---|---|---|
| castle | string | yes | Slug (preferred, e.g. "himeji-castle") or exact name |
No output schema declared.
No examples provided.
get_statistics Atlas statistics ~72
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/.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
list_countries Countries with castle counts ~55
Every country in the atlas with its landmark count, most first — answers "which country has the most castles" (France leads). Returns country name and ISO code per row; country pages are browsable from the countries_index URL.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
random_castle A random castle ~50
One random landmark with its full record, optionally limited to a country — for discovery, quizzes and "castle of the day" features.
| Name | Type | Req | Description |
|---|---|---|---|
| country | string | – | Country name or ISO code (optional) |
No output schema declared.
No examples provided.
search_castles Search castles by name ~162
Search the atlas’s 8,672 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.
| Name | Type | Req | Description |

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 (Great Wall of China). The direct answer to "most famous castles in <country>"; filter by country and/or category.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | – |
| country | string | – | Country name or ISO code (optional — omit for worldwide) |
