compass vs vector_mcp

compass: Compass is a context engine that builds a temporal knowledge graph connecting entities, relationships, and documents across systems. It provides AI-native capabilities, hybrid search, impact analysis, and an open type system. It can be used to query and traverse organizational knowledge for humans and AI agents.; vector_mcp: VectorMCP is a Ruby framework implementing the MCP server specification. It provides class-based tools, resources, prompts, and supports streamable HTTP transport with authentication, authorization, and middleware.
