Advanced filesystem operations for Claude Desktop with large file handling capabilities and Claude-optimized features. This MCP server provides fast file reading and writing with chunking support, enabling efficient handling of very large files through streaming and chunked reads. It supports sequential reading of large files using continuation tokens to process data end-to-end. Large file operations are complemented by streaming writes that scale with file size while maintaining memory efficiency. Directory operations cover listing, creation, and management, and a robust File Search feature enables name- and content-based queries with filtering. The design emphasizes Claude-optimized response formats, memory-efficient streaming, and smart exclusions to reduce unnecessary data. Backup and recovery are built-in and configurable; by default backups are disabled, but can be enabled via CREATE_BACKUP_FILES, with timestamped backups like file.txt.backup.1755485284402 to prevent data loss during edits. Debug/logging can be tuned via environment variables to aid development, while safety measures help avoid JSON-RPC errors in Claude Desktop. Overall, the server focuses on reliability, performance, and scalable filesystem operations for Claude Desktop workflows.
