Wax vs FastMCP
Wax: Wax provides persistent, searchable, and private on-device memory for iOS and macOS AI agents, eliminating the need for servers or cloud services. It integrates document storage, semantic search (HNSW), full-text search (BM25), and token budgeting into a single, crash-safe .wax file.; FastMCP: FastMCP is a Python framework that simplifies the creation of applications adhering to the Model Context Protocol (MCP), enabling AI agents to connect seamlessly with tools and data. It streamlines complex protocol implementation, focusing on delivering the right information to agents at the right time.
