Claude Code Memory Server

A Neo4j-based Model Context Protocol (MCP) server that provides intelligent memory capabilities for Claude Code, enabling persistent knowledge tracking, relationship mapping, and contextual development assistance.

Overview

This MCP server creates a sophisticated memory system that tracks Claude Code's activities, decisions, and learned patterns to provide contextual memory across sessions and projects. It uses Neo4j as a graph database to capture and analyze complex relationships between development concepts, solutions, and workflows.

Features

Core Memory Operations

Persistent Memory Storage - Store development tasks, solutions, and patterns
Intelligent Search - Find relevant memories by context, content, or relationships
Relationship Mapping - Track how different concepts, files, and solutions relate
Context Awareness - Project-specific and technology-specific memory retrieval

Advanced Intelligence

Pattern Recognition - Automatically identify reusable development patterns
Solution Effectiveness - Track and learn from successful approaches
Workflow Memory - Remember and suggest optimal development sequences
Error Prevention - Learn from past mistakes to prevent similar issues

Development Integration

Task Execution Tracking - Monitor what Claude Code does and how
Code Pattern Analysis - Identify and store successful code patterns
Project Context Memory - Understand codebase conventions and dependencies
Collaborative Learning - Share knowledge across development sessions

Architecture

Memory Types

Task - Development tasks and their execution patterns
CodePattern - Reusable code solutions and architectural decisions
Problem - Issues encountered and their context
Solution - How problems were resolved and their effectiveness
Project - Codebase context and project-specific knowledge
Technology - Framework, language, and tool-specific knowledge

Relationship Types

The system tracks seven categories of relationships:

Causal - CAUSES, TRIGGERS, LEADS_TO, PREVENTS, BREAKS
Solution - SOLVES, ADDRESSES, ALTERNATIVE_TO, IMPROVES, REPLACES
Context - OCCURS_IN, APPLIES_TO, WORKS_WITH, REQUIRES, USED_IN
Learning - BUILDS_ON, CONTRADICTS, CONFIRMS, GENERALIZES, SPECIALIZES
Similarity - SIMILAR_TO, VARIANT_OF, RELATED_TO, ANALOGY_TO, OPPOSITE_OF
Workflow - FOLLOWS, DEPENDS_ON, ENABLES, BLOCKS, PARALLEL_TO
Quality - EFFECTIVE_FOR, INEFFECTIVE_FOR, PREFERRED_OVER, DEPRECATED_BY, VALIDATED_BY
