mcp-ts-core vs ontosphere

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.; ontosphere: Ontosphere is a browser-based RDF/ontology knowledge graph editor that loads RDF from files, URLs, or SPARQL endpoints, allows users to author nodes and edges on a canvas, runs OWL 2 DL reasoning with visual differentiation of inferred triples, and supports multi-algorithm layout and AI-agent integration via the Model Context Protocol.
