mcp-ts-core vs vector_mcp

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.; vector_mcp: VectorMCP is a Ruby framework implementing the MCP server specification. It provides class-based tools, resources, prompts, and supports streamable HTTP transport with authentication, authorization, and middleware.
