3dcitydb-mcp-server vs daimon-memory

3dcitydb-mcp-server: 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.; daimon-memory: Daimon-memory is a self-hostable memory backend for AI agents, storing typed records in PostgreSQL with Qdrant as a semantic index. It provides fast, cheap, and reproducible hybrid keyword + vector search recall without an LLM in the recall path.
