Kremis is a deterministic knowledge graph MCP server in Rust that records, associates, and retrieves facts without any LLM or probabilistic components, ensuring verifiable and grounded responses. Its unique value lies in providing a provably honest memory layer for AI agents and compliance workflows, with ACID transactions, cryptographic hash integrity, and a canonical export format. This project is interesting because it solves the LLM hallucination problem by design, not by more prompting.

Target audience: backend devs, data engineers, AI engineers
