OWL (Web Ontology Language)

OWL-MCP is a Model Context Protocol server for managing Web Ontology Language (OWL) ontologies, providing tools for adding, removing, and finding axioms in OWL files. Built with py-horned-owl for ontology manipulation, it features thread-safe operations, automatic file synchronization, and a configuration system for managing named ontologies with consistent settings. The server exposes standardized MCP tools that enable AI assistants to directly manipulate ontologies through string-based axiom representations in OWL functional syntax, making it particularly valuable for semantic web applications, knowledge graph management, and ontology development without requiring deep understanding of complex object models.
