Onto
MCP server for LLM agents: check an artifact's ontological integrity (the logical consistency of its concepts, authority, and purpose) and derive a domain ontology from real sources, with every structured claim gated by runtime validation.
Works with: Claude Code, Cursor, Claude Desktop, Codex CLI, Gemini CLI, Cline, Windsurf, VS Code (installable)
installable: each client documents how to load an MCP server of this type — that is the client's promise, not a claim verified against this capability
