Castles is a Model Context Protocol (MCP) server: Castles, fortresses, palaces and ruins worldwide: search, nearby, fame ranking, statistics. CC0. In practice that means any MCP-compatible AI assistant can call Castles's tools directly — the model decides when to use them in a conversation or agent run.
It's a hosted (remote) server — point your client at https://thecastlemap.com/mcp and you're connected, with nothing to install locally. The current release is v1.0.3, published under the MIT license, with source at Flightmussy/castlemap-mcp on GitHub.
Castles is listed under AI & Agents on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
