Wax vs MCP-Nest
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.; MCP-Nest: This NestJS module simplifies exposing AI tools, resources, and prompts using the Model Context Protocol (MCP). It integrates seamlessly with NestJS's dependency injection to build complex, enterprise-ready MCP servers.
