Memory Arbiter MCP

A local-first, community-driven MCP server that provides a shared SQLite-based memory layer for AI agents. It enables cross-session recall, sentence-level evidence retrieval, and local conflict detection using a self-trained mDeBERTa model, ensuring facts are verified and conflicts are surfaced before overwriting.
