I built an MCP server for a knowledge graph. It doesn't call any LLM.

I built an MCP server for a knowledge graph. It doesn't call any LLM.

Short summary

Kremis is a Rust-based graph store providing deterministic memory for Claude via MCP without calling external LLMs. Unlike vector search, it guarantees accurate answers to queries by storing and retrieving entity-attribute-value triples. Open-source and minimal-dependency, designed for applications where data structure is known and accuracy matters more than similarity search.

  • Kremis provides deterministic, LLM-free memory for Claude through MCP
  • Uses entity-attribute-value triples for guaranteed accuracy over similarity matching
  • Open-source, Rust-based, minimal dependencies, ready to integrate

Generated with AI, which can make mistakes.
