Memory Compression Engine: Auto-compresses chat/memory content to reduce tokens and latency
- 5 compression algorithms: whitespace, filler, semantic, aggressive, balanced
- Auto-selects optimal algorithm based on content analysis
- Batch compression support for multiple texts
- Live savings metrics (tokens saved, latency reduction, compression ratio)
- Real-time statistics tracking across all compressions
- Integrated into memory storage with automatic compression
- REST API endpoints:
/api/compression/compress,/api/compression/batch,/api/compression/analyze,/api/compression/stats - Example usage in
examples/backend/compression-examples.mjs

VS Code Extension with AI Auto-Link
- Auto-links OpenMemory to 6 AI tools: Cursor, Claude, Windsurf, GitHub Copilot, Codex
- Dual mode support: Direct HTTP or MCP (Model Context Protocol)
- Status bar UI with clickable menu for easy control
- Toggle between HTTP/MCP mode in real-time
- Zero-config setup - automatically detects backend and writes configs
- Performance optimizations:
- ESH (Event Signature Hash): Deduplicates ~70% redundant saves
- HCR (Hybrid Context Recall): Sub-80ms queries with sector filtering
- MVC (Micro-Vector Cache): 32-entry LRU cache saves ~60% embedding calls
- Settings for backend URL, API key, MCP mode toggle
- Postinstall script for automatic setup
-
API Authentication & Security
- API key authentication with timing-safe comparison
- Rate limiting middleware (configurable, default 100 req/min)
- Compact 75-line auth implementation
- Environment-based configuration
-
CI/CD
- GitHub Action for automated Docker build testing
- Ensures Docker images build successfully on every push
- Optimized all compression code for maximum efficiency
- Removed verbose comments and long variable names
- Active voice, casual naming convention throughout compression engine
- Streamlined memory routes with integrated compression
- Ultra-compact compression implementation (<100 lines core logic)
- VS Code extension connection issues (health endpoint)
- MCP protocol integration for AI tools
- Extension now properly passes MCP flag to all writers
