Key Features of memories-with-lessons-mcp-server

memories-with-lessons-mcp-server is packed with features that make it a powerful tool for AI memory management:

Entities and Relations: The server uses a knowledge graph structure where entities (like people, organizations, events) are nodes connected by relations, enabling complex data interconnections.
Observations: Discrete pieces of information about entities are stored and managed as observations, which can be added or removed dynamically.
Lesson System: Captures knowledge about errors and their solutions, allowing the AI to learn from past mistakes. Lessons include error patterns, solution steps, and success rate tracking.
Comprehensive API Tools: Offers a range of API functionalities, such as creating entities and relations, adding or deleting observations, and managing the knowledge graph.
Lesson Management: Tools for creating lessons, finding similar errors, updating success metrics, and getting lesson recommendations ensure the AI continues to improve its problem-solving capabilities.
File Management: Efficiently handles memory and lesson data through structured JSON files, with automatic file splitting for optimal performance.
Integration Flexibility: Easily integrates with various AI clients, supporting both Docker and NPX configurations to suit different development environments.

This server is a versatile addition to any AI system, enhancing its memory and learning capabilities, resulting in a smarter, more adaptive assistant.

A basic implementation of persistent memory using a local knowledge graph. This lets Claude remember information about the user across chats and learn from past errors through a lesson system.

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:

 "name": "John_Smith",
 "entityType": "person",
 "observations": ["Speaks fluent Spanish"]

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:

 "from": "John_Smith",
 "to": "Anthropic",
 "relationType": "works_at"

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:

 "entityName": "John_Smith",
 "observations": [
 "Speaks fluent Spanish",
 "Graduated in 2019",
 "Prefers morning meetings"

Lessons

Lessons are special entities that capture knowledge about errors and their solutions. Each lesson has:

A unique name (identifier)
Error pattern information (type, message, context)
Solution steps and verification
Success rate tracking
Environmental context
Metadata (severity, timestamps, frequency) Example:

 "name": "NPM_VERSION_MISMATCH_01",
 "entityType": "lesson",
 "observations": [
 "Error occurs when using incompatible package versions",
 "Affects Windows environments specifically",
 "Resolution requires version pinning"
 "errorPattern": {
 "type": "dependency",
 "message": "Cannot find package @shadcn/ui",
 "context": "package installation"
 "metadata": {
 "severity": "high",
 "environment": {
 "os": "windows",
 "nodeVersion": "18.x"
 "createdAt": "2025-02-13T13:21:58.523Z",
 "updatedAt": "2025-02-13T13:22:21.336Z",
 "frequency": 1,
 "successRate": 1.0
 "verificationSteps": [
 "command": "pnpm add shadcn@latest",
 "expectedOutput": "Successfully installed shadcn",
 "successIndicators": ["added shadcn"]

Usage with Claude Desktop

Setup

Add this to your claude_desktop_config.json:

Docker

 "mcpServers": {
 "memory": {
 "command": "docker",
 "args": ["run", "-i", "-v", "claude-memory:/app/dist", "--rm", "mcp/memory"]

NPX

 "mcpServers": {
 "memory": {
 "command": "npx",
 "args": [
 "-y",
 "@modelcontextprotocol/server-memory"

NPX with custom setting

The server can be configured using the following environment variables:

 "mcpServers": {
 "memory": {
 "command": "npx",
 "args": [
 "-y",
 "@modelcontextprotocol/server-memory"
 "env": {
 "MEMORY_FILE_PATH": "/path/to/custom/memory.json"

MEMORY_FILE_PATH: Path to the memory storage JSON file (default: memory.json in the server 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.

Follow these steps for each interaction:
1. User Identification:
 - You should assume that you are interacting with default_user
 - If you have not identified default_user, proactively try to do so.
2. Memory Retrieval:
 - Always begin your chat by saying only "Remembering..." and retrieve all relevant information from your knowledge graph
 - Always refer to your knowledge graph as your "memory"
3. Memory
 - While conversing with the user, be attentive to any new information that falls into these categories:
 a) Basic Identity (age, gender, location, job title, education level, etc.)
 b) Behaviors (interests, habits, etc.)
 c) Preferences (communication style, preferred language, etc.)
 d) Goals (goals, targets, aspirations, etc.)
 e) Relationships (personal and professional relationships up to 3 degrees of separation)
4. Memory Update:
 - If any new information was gathered during the interaction, update your memory as follows:
 a) Create entities for recurring organizations, people, and significant events
 b) Connect them to the current entities using relations
 b) Store facts about them as observations

Building

Docker:

docker build -t mcp/memory -f src/memory/Dockerfile .
