ontoskills vs mcp-use
ontoskills: OntoSkills transforms natural language skill definitions into validated OWL 2 ontologies—queryable knowledge graphs that enable deterministic reasoning for AI agents. It solves the problem of probabilistic LLM skill interpretation by compiling skills to ontologies and querying with SPARQL for exact answers.; mcp-use: mcp-use is a full-stack framework for Model Context Protocol (MCP), enabling the creation of MCP servers, clients, and AI agents. It supports development in both Python and TypeScript with minimal code.
