MCP Memory ServerMCP server — stores local knowledge graphs as JSONL
Agents can now distinguish read, write, and destructive graph actions before calling tools. Small change, useful for safer MCP orchestration.
- Read tools like
read_graph,search_nodes, andopen_nodesare marked read-only and idempotent, reducing approval friction. - Write tools such as
create_entitiesandadd_observationsare tagged non-destructive, a cleaner signal for agent planners. - Delete tools are marked destructive and idempotent, making risk checks easier in MCP clients and IDE agents.
