Researchers present Euclid-MCP, an open-source Model Context Protocol server that connects LLM agents to SWI-Prolog for deterministic logical reasoning. The system introduces Euclid-IR, an intermediate representation for Horn-clause logic that LLMs can generate and that compiles to Prolog, enabling a translate-run-inspect-repair loop with full proof traces. Evaluation on an IT security and compliance use case shows LLMs alone hallucinate on larger knowledge bases while Euclid-MCP delivers exact answers with lower latency. The authors argue semantic RAG is fundamentally unsuited for rule enforcement, positioning Euclid-MCP as a shared reasoning substrate for agentic systems.
