Memkeeper Overview

teflon07/memkeeper MCP server gives agents durable local memory through MCP over JSON-RPC on stdio. It stores memories in one SQLite file and retrieves them with lexical BM25/FTS search, optional on-device ONNX embeddings, and cross-encoder reranking. Reach for it when an agent needs persistent context across sessions without a hosted service, network calls, or API keys.

Primary Use Cases for Memkeeper:
  • Store durable agent preferences across sessions
  • Retrieve project decisions with local semantic search
  • Capture structured facts and entity relationships
  • Inject relevant memories into Claude Code prompts
