tether-memory MCP

A local-first agent memory server that provides four core verbs: remember, recall, link, and forget. It uses a local SQLite database with hybrid search combining FTS5 keyword hits and static embeddings, fused with a usage graph for associative recall. The system supports upserts to prevent duplication, auto-loaded boot indexes for project awareness, and safe parallel tool calls. It degrades gracefully without network dependencies, though it offers optional sync via libSQL/Turso.
