You run an MCP server that stores a knowledge graph in DuckDB and exposes memory-backed reasoning for Claude Desktop. It lets you persist entities, observations, and relations, and query them with SQL-backed and fuzzy search capabilities to improve memory retrieval across interactions.

How to use

Begin by starting the memory server and then interact with it through your MCP client. You will connect to the graph-memory MCP and perform memory-related operations like retrieving relevant information, updating memory with new observations, and managing entities and relations.

How to install

Prerequisites you need installed on your system before proceeding are Node.js (with npm or npx) and a working command shell.

Available tools

Memory Retrieval

Retrieve relevant information from the memory graph using a combination of SQL queries against the DuckDB backend and fuzzy matching to surface the most relevant entities, observations, and relations.

Memory Update

Update the memory graph by creating entities, linking them with relations, and storing observations to reflect new information gathered during interactions.

Entity and Relation Management

Create and organize entities, establish relations between them, and maintain a coherent knowledge graph over time.
