What your AI can do with Castles
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “search_castles”: Search the atlas’s 8,138 castles, fortresses, palaces and ruins by name (accent- and case-insensitive substring match). Optionally filter by.”
“Use “get_castle”: Fetch one landmark’s full record by slug (preferred, e.g. "palace-of-versailles") or exact name: coordinates, founding year and century, wor.”
“Use “castles_near”: List landmarks within a radius of a WGS84 coordinate, nearest first, each with distance_km. Radius defaults to 100 km (max 2,000). For "cast.”
“Use “top_castles”: The most famous landmarks worldwide or in one country, ordered by Castlemap fame rank — a blend of Wikipedia coverage and readership; rank 1.”
How secure is the Castles MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Castles holds up.
Official endpoint
Operated by Castles (thecastlemap.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If Castles adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps
Connect your gate
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Pick Castles
Choose Castles in the gate directory. No sign-in needed.
Use it anywhere
Castles's tools are live in every AI client you've connected — with rules and logging built in.

Who runs the Castles MCP server?
The Castles MCP server at a glance
https://thecastlemap.com/mcpQuestions, answered
Is there an official Castles MCP server?
Yes — Castles operates its own remote MCP server at thecastlemap.com. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect Castles to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Castles in the directory. No account or sign-in is needed. From then on, Castles's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Castles runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Castles MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
