3dcitydb-mcp-server

Active·★ 18·Apache-2.0·Updated 2026-10-22

The 3DCityDB MCP Server enables AI assistants to access and reason about semantic 3D city models stored in a 3DCityDB v5 geodatabase using natural language. It dynamically resolves CityGML schema, properties, and attributes, allowing AI to execute SQL queries and understand spatial and semantic information without manual prompt engineering.

3dcitydb-mcp-server
↗

A Model Context Protocol (MCP) server that gives AI assistants (Claude Code, Claude Desktop, and any MCP-compatible client) direct, natural language access to semantic 3D city models in CityGML managed within a 3DCityDB V5. Also includes an agentic Chatbot application using the MCP server with commercial or locally running LLMs.
