Knowledge Graph Memory Server
An improved implementation of persistent memory using a local knowledge graph with a customizable memory path.
This lets Claude remember information about the user across chats.
[!NOTE] This is a fork of the original Memory Server and is intended to not use the ephemeral memory npx installation method.

Core Concepts
Entities
Entities are the primary nodes in the knowledge graph. Each entity has:
- A unique name (identifier)
- An entity type (e.g., "person", "organization", "event")
- A list of observations
- Creation date and version tracking
The version tracking feature helps maintain a historical context of how knowledge evolves over time.
Example:
Relations
Relations define directed connections between entities. They are always stored in active voice and describe how entities interact or relate to each other. Each relation includes:
- Source and target entities
- Relationship type
- Creation date and version information
This versioning system helps track how relationships between entities evolve over time.
Example:
Observations
Observations are discrete pieces of information about an entity. They are:
- Stored as strings
- Attached to specific entities
- Can be added or removed independently
- Should be atomic (one fact per observation)
Example:
API
Tools
- create_entities
- create_relations
- add_observations
- delete_entities
- delete_observations
- delete_relations
- read_graph
- search_nodes
- open_nodes
Usage with Cursor, Cline or Claude Desktop
Setup
Add this to your mcp.json or claude_desktop_config.json:
Installing via Smithery
To install Knowledge Graph Memory Server for Claude Desktop automatically via Smithery:
Custom Memory Path
You can specify a custom path for the memory file in two ways:
- Using command-line arguments:
- Using environment variables:
If no path is specified, it will default to memory.jsonl in the server's installation directory.
System Prompt
The prompt for utilizing memory depends on the use case. Changing the prompt will help the model determine the frequency and types of memories created.
Here is an example prompt for chat personalization. You could use this prompt in the "Custom Instructions" field of a Claude.ai Project.
