🏗️ Project Convention Learning

The Enhanced MCP Memory Server automatically learns and remembers project-specific conventions to prevent AI assistants from suggesting incorrect commands or approaches:

Automatic Detection

• Operating System: Windows vs Unix, preferred shell and commands
• Project Type: Node.js, Python, Rust, Go, Java, MCP servers, FastAPI, Django
• Development Tools: IDEs, linters, formatters, CI/CD configurations
• Package Management: npm, yarn, pip, poetry, cargo, go modules
• Build Systems: Vite, Webpack, Make, batch scripts, shell scripts

Smart Command Suggestions

# Instead of generic commands, suggests project-specific ones:
User types: "node server.js"
AI suggests: "Use 'npm run dev' instead for this project"

User types: "python main.py" 
AI suggests: "Use 'uvicorn main:app --reload' for this FastAPI project"

Windows Optimization

• Automatically detects Windows environment
• Uses cmd.exe and Windows-appropriate path separators
• Suggests Windows-compatible commands (e.g., dir instead of ls)
• Handles Windows-specific Python and Node.js patterns

Memory Integration

All learned conventions are stored as high-importance memories that:

• Appear in AI context for every interaction
• Persist across sessions and project switches
• Include environment warnings and project-specific guidance
• Prevent repeated incorrect command suggestions

🔧 Configuration Options

Configure via environment variables:

Variable	Default	Description
LOG_LEVEL	INFO	Logging level (DEBUG, INFO, WARNING, ERROR)
MAX_MEMORY_ITEMS	1000	Maximum memories per project
MAX_CONTEXT_TOKENS	8000	Token threshold for auto-compression
CLEANUP_INTERVAL_HOURS	24	Auto-cleanup interval
ENABLE_AUTO_CLEANUP	true	Enable automatic cleanup
MAX_CONCURRENT_REQUESTS	5	Max concurrent requests
REQUEST_TIMEOUT	30	Request timeout in seconds
MEMORY_ENABLE_SECRET_FILTER	true	Redact detected credentials (AWS keys, GitHub tokens, JWTs, etc.) before any DB write. Set false to disable.
MEMORY_STRICT_SECRET_MODE	false	When true, refuse to persist any content containing a detected secret instead of saving the redacted version.
DATA_DIR	~/ClaudeMemory	Where to store data and logs

🧪 Testing

The package ships with a pytest suite covering the secret filter, the task status update path, memory deduplication, and basic search. To run it:

pip install -e ".[dev]"
pytest

The suite is safe to run anywhere — every test uses tmp_path and never touches the production data/ directory. Add new tests under tests/ next to any change in behaviour.

• Response time monitoring for all tools
• Success rate tracking with error counts
