fastmcp vs memem
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.; memem: memem is a Claude Code plugin that gives persistent memory across sessions. It automatically extracts durable lessons from completed sessions, stores them as markdown in an Obsidian vault, and surfaces relevant ones as an Active Memory Slice. It is local-first with no cloud services.
