Ombre-Brain vs fastmcp
Ombre-Brain: Ombre Brain is a long-term emotional memory system for Claude. It tags memories using Russell's valence/arousal coordinates, stores them as Obsidian-compatible Markdown, connects via MCP, and implements a forgetting curve. It features natural decay and active surfacing of unresolved memories.; 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.
