Built with FastMCP 2.0 for modern LLM integration, optimized for GitHub Copilot workflows.

✨ Key Features

🧠 Intelligent Memory Operations

• Semantic Search: Find relevant memories using natural language queries
• Association Discovery: Automatically discover connections between concepts
• Complete CRUD: Create, Read, Update, Delete with full lifecycle management
• Smart Organization: Hierarchical scopes with auto-categorization

🔍 Advanced Discovery

• Top-K Search: Optimized threshold (0.1) with LLM-guided relevance judgment
• Cross-Scope Associations: Find connections across different knowledge scopes
• Similarity Scoring: Transparent relevance metrics for intelligent filtering
• Creative Connections: Discover unexpected relationships for innovation

🗂️ Powerful Organization

• Hierarchical Scopes: work/projects/name, learning/technology, personal/ideas
• Flexible Categorization: Tags, metadata, and automatic scope suggestions
• Session Management: Temporary workspaces for project isolation
• Memory Movement: Reorganize knowledge as understanding evolves

🔄 Cross-Environment Sync

• Export/Import: Backup and restore memories across development environments
• Multiple Formats: JSON, YAML with compression support
• Merge Strategies: Handle duplicates intelligently during sync
• Git Workflow: Integrate memory backup into version control processes

🛠️ Developer Experience

• GitHub Copilot Integration: Natural language memory operations
• VS Code Tasks: One-click server management and maintenance
• Real-time Association: Automatic relationship discovery during storage
• Performance Optimized: Sub-second search across thousands of memories
• Response Level Control: Minimal, standard, or full detail responses for optimal token usage

⚡ Smart Response Levels

Control response detail and token usage with three intelligent levels:

• minimal: Essential information only (~50 tokens) - Perfect for status checks and basic operations
• standard: Balanced detail for workflow continuity (default) - Optimal for most use cases
• full: Comprehensive data including metadata, associations, and analysis - Ideal for debugging and detailed exploration

Example Usage:

# Quick status check
memory_store(content="meeting notes", response_level="minimal")
# Returns: {"success": true, "message": "Memory stored", "memory_id": "..."}

# Full debugging info
memory_search(query="project ideas", response_level="full") 
# Returns: Complete results with similarity scores, metadata, associations

Technology Stack

• Language: Python 3.11+
• MCP Framework: FastMCP 2.0
• Vector Database: ChromaDB
• Embedding Model: OpenAI Embeddings / Sentence Transformers
• Graph Database: NetworkX (in-memory)
• Storage: SQLite (metadata)

Installation & Usage

For detailed setup instructions, see docs/installation.md.

Server Startup

Direct STDIO Mode (Recommended)

Standard MCP startup method:

python -m mcp_assoc_memory.server --config config.json

The server operates in STDIO mode for direct MCP client integration. This is the recommended approach for VS Code Copilot and other MCP clients.

Configuration

• Copy config.json.template to config.json
• Set your OpenAI API key for embeddings
• Configure transport options (STDIO enabled by default)

Database Path Configuration

🆕 Workspace Pollution Avoidance (NEW): The server now stores database files in OS-appropriate user directories by default, keeping your workspace clean.

Default Locations:

• Linux: ~/.local/share/mcp-assoc-memory/
• macOS: ~/Library/Application Support/mcp-assoc-memory/
• Windows: %APPDATA%/mcp-assoc-memory/

Override with Environment Variables:

export MCP_DATABASE_PATH="/custom/path/memory.db"
export MCP_DATA_DIR="/custom/data/directory"

See Database Path Configuration for detailed options.

Environment Variables

• OPENAI_API_KEY: Required for OpenAI embeddings
• MCP_LOG_LEVEL: Set logging level (DEBUG, INFO, WARNING, ERROR)
• MCP_DATABASE_PATH: Override database file location
• MCP_DATA_DIR: Override data directory location

🛠️ Installation (PyPI, pipx, GitHub)

Recommended: PyPI

pip install mcp-assoc-memory

pipx (isolated global install)

pipx install mcp-assoc-memory

GitHub (latest/dev version)

pip install git+https://github.com/mako10k/mcp-assoc-memory.git
# or
pipx install git+https://github.com/mako10k/mcp-assoc-memory.git

Start the server (after install)

python -m mcp_assoc_memory.server --config config.json

• Configure via .vscode/mcp.json for VS Code Copilot integration
• MCPクライアントや自動検出ツール（Claude Desktop Extensions, FastMCP, Cursor等）からも自動認識されます。
• Dockerイメージも近日公開予定。
