Description

This MCP server provides domain-based persistent memory via a local knowledge graph, enabling AI agents to maintain context across chat sessions. It supports JSON, SQLite, and MariaDB storage backends, STDIO and HTTP transports, full-text search (for SQL backends), fuzzy/regex search, and cross-domain graph traversal. The system includes tools for domain management, memory CRUD operations, search, and Mermaid visualization of relationships, and is deployable locally or via Docker/Docker Compose. It is suitable for building stateful assistants that require long-term, searchable, and structured memory.
