Integrations
optimized-memory-mcp-server
This is to test and demonstrate Claude AI's coding abilities, as well as good AI workflows and prompt design. This is a fork of a Python Memory MCP Server (I believe the official one is in Java) which uses SQLite for a backend.
Knowledge Graph Memory Server
A basic implementation of persistent memory using a local knowledge graph. This lets Claude remember information about the user across chats.
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
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.
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 multiple new entities in the knowledge graph
- Input:
entities
(array of objects)- Each object contains:
name
(string): Entity identifierentityType
(string): Type classificationobservations
(string[]): Associated observations
- Each object contains:
- Ignores entities with existing names
- create_relations
- Create multiple new relations between entities
- Input:
relations
(array of objects)- Each object contains:
from
(string): Source entity nameto
(string): Target entity namerelationType
(string): Relationship type in active voice
- Each object contains:
- Skips duplicate relations
- add_observations
- Add new observations to existing entities
- Input:
observations
(array of objects)- Each object contains:
entityName
(string): Target entitycontents
(string[]): New observations to add
- Each object contains:
- Returns added observations per entity
- Fails if entity doesn't exist
- delete_entities
- Remove entities and their relations
- Input:
entityNames
(string[]) - Cascading deletion of associated relations
- Silent operation if entity doesn't exist
- delete_observations
- Remove specific observations from entities
- Input:
deletions
(array of objects)- Each object contains:
entityName
(string): Target entityobservations
(string[]): Observations to remove
- Each object contains:
- Silent operation if observation doesn't exist
- delete_relations
- Remove specific relations from the graph
- Input:
relations
(array of objects)- Each object contains:
from
(string): Source entity nameto
(string): Target entity namerelationType
(string): Relationship type
- Each object contains:
- Silent operation if relation doesn't exist
- read_graph
- Read the entire knowledge graph
- No input required
- Returns complete graph structure with all entities and relations
- search_nodes
- Search for nodes based on query
- Input:
query
(string) - Searches across:
- Entity names
- Entity types
- Observation content
- Returns matching entities and their relations
- open_nodes
- Retrieve specific nodes by name
- Input:
names
(string[]) - Returns:
- Requested entities
- Relations between requested entities
- Silently skips non-existent nodes
Usage with Claude Desktop
Setup
Add this to your claude_desktop_config.json:
Docker
NPX
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.

hybrid server
The server is able to function both locally and remotely, depending on the configuration or use case.
A persistent memory implementation using a local knowledge graph that lets Claude remember information about users across conversations.
