Fixed the initialization timeout issue with minimal changes: 1. Added stdout flush after server connection to combat Docker buffering 2. Fixed docker-entrypoint.sh to not output to stdout in stdio mode 3. Added process.stdin.resume() to keep server alive 4. Added IS_DOCKER environment variable for future use 5. Updated README to prioritize Docker with correct -i flag configuration The core issue was Docker's block buffering preventing immediate JSON-RPC responses. The -i flag maintains stdin connection, and explicit flushing ensures responses reach Claude Desktop immediately. Also fixed "Shutting down..." message that was breaking JSON-RPC protocol by redirecting it to stderr in stdio mode. Docker is now the recommended installation method as originally intended. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
