Memento

Adds 20 MCP tools that give Claude persistent memory across sessions using a local knowledge graph. Store decisions, preferences, and context with `store_memory`, then retrieve them later with `recall_memory` or `find_related` (hybrid full-text and semantic search). Includes graph traversal for entity relationships, contradiction detection, memory versioning with `evolve_memory`, and project management primitives. Runs locally with PostgreSQL and Ollama for embeddings and entity extraction. Connect it to Claude Desktop, Cursor, Windsurf, or any MCP client. Point multiple team members at the same database for shared architectural memory. Good for long-running projects where you're tired of re-explaining decisions every session.
