About Memory MCP Server
How to Use Memory MCP Server
1
Connect @modelcontextprotocol/server-memory to an MCP host and begin with a small graph. Create a few entities and relations, add atomic observations, then test search_nodes and open_nodes before relying on the memory automatically. Review the graph periodically and delete obsolete observations or relationships rather than allowing unbounded accumulation.

create_relations

add_observations
