Features

  • Graph Memory - Memories as nodes, relationships as edges, observations as content

  • Unified Search - Semantic vectors, exact matching, wildcards, and graph traversal in one tool

  • Smart Relations - Typed connections with strength, source tracking, and temporal metadata

  • Multi-Database - Isolated project contexts with instant switching

  • Batch Operations - Create multiple memories with relationships in single request using localId

  • Context Control - Response detail levels: minimal (lists), full (complete data), relations-only

  • Time Queries - Filter by relative ("7d", "30d") or absolute dates on any temporal field

  • Graph Traversal - Navigate networks in any direction with depth control

  • MCP Native - Seamless integration with Claude Desktop and MCP clients

  • Persistent Storage - Neo4j graph database with GDS plugin for vector operations

Tools (4)

  • memory_store

    Create memories with observations and immediate relations in ONE operation

  • memory_find

    Unified search/retrieval with semantic search, direct ID lookup, date filtering, and graph traversal

  • memory_modify

    Comprehensive modification operations (update, delete, observations, relations)

  • database_switch

    Switch database context for isolated environments
