okf-agent-memory vs 3dcitydb-mcp-server

okf-agent-memory: OKF Agent Memory provides a domain-neutral, Git-native persistent project memory for AI agents, leveraging the Dual-Memory Agent Architecture to prevent context bloat and memory rot. It uses an ultra-compact behavioral codex and a queryable OKF v0.2 knowledge bundle, with blazing-fast, zero-cost local retrieval.; 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.
