mcp-ts-core vs post-cortex

mcp-ts-core: @cyanheads/mcp-ts-core is a TypeScript framework for building MCP servers. It offers declarative tool/resource/prompt definitions with Zod schemas, pluggable authentication, multi-backend storage, OpenTelemetry observability, and runs on both local (stdio/HTTP) and edge (Cloudflare Workers) runtimes. The framework handles infrastructure concerns like transport, auth, storage, config, logging, and lifecycle, so developers can focus on writing business logic.; post-cortex: Post-Cortex is an MCP server that provides AI assistants with persistent memory. It stores conversations, decisions, and insights in a searchable knowledge base with automatic entity extraction. All processing runs locally with no external API calls, ensuring privacy.
