mcp-ts-core vs node9-proxy

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.; node9-proxy: Node9 is an execution security layer for AI agents that intercepts dangerous shell commands and tool calls in real-time. It features a multi-channel approval system (native popup, browser, Slack, terminal), a flight recorder for live monitoring, and an AI negotiation loop to guide safer behavior. It also includes DLP content scanning and shadow git snapshots for undo.
