fastmcp vs compass
fastmcp: FastMCP is a standard framework for building Model Context Protocol (MCP) applications, which connect LLMs to tools and data. It simplifies the process by automatically generating schemas, validation, and documentation for tools, and managing transport negotiation and authentication for server connections. FastMCP offers a comprehensive solution for developing, deploying, and scaling MCP-powered systems.; 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.
