File System MCP

A foundational File System MCP server for persistent file operations with shareable URLs and dashboard integration.

Features

• Complete File Operations: Create, read, update, delete files and directories
• Secure Workspace: All operations confined to user workspace with path validation
• Shareable URLs: Generate time-limited shareable links for files
• File Search: Search by filename patterns or file content
• Rich Metadata: File type detection, timestamps, permissions, and MIME types
• Dashboard Ready: Designed for integration with platform dashboard
• Future 3rd Party Integration: Extensible for OneDrive, Google Drive, etc.

MCP Tools

Core File Operations

1. list_files - List files and directories with optional recursive scanning
2. read_file - Read file contents with encoding support
3. write_file - Write/create files with automatic directory creation
4. delete_file - Delete files or directories safely
5. create_directory - Create directories including parent paths

Advanced Features

6. get_file_info - Get detailed file metadata (size, dates, permissions, MIME type)
7. search_files - Search by filename patterns or content with configurable limits
8. get_shareable_url - Generate shareable URLs with expiration times

Usage Examples

Basic File Operations

// List files in workspace root
await mcp.callTool('list_files', { path: '.', recursive: false });

// Create a document
await mcp.callTool('write_file', {
  path: 'documents/report.md',
  content: '# Project Report\n\nThis is my project report...'
});

// Read the document
await mcp.callTool('read_file', { path: 'documents/report.md' });

File Management

// Create project structure
await mcp.callTool('create_directory', { path: 'projects/website' });

// Get file information
await mcp.callTool('get_file_info', { path: 'documents/report.md' });

// Search for files
await mcp.callTool('search_files', {
  pattern: '*.md',
  search_content: true,
  max_results: 20
});

Sharing and URLs

// Generate shareable URL for a PDF
await mcp.callTool('get_shareable_url', {
  path: 'documents/presentation.pdf',
  expires_in: 48  // 48 hours
});

Integration Features

Dashboard Integration

• File listing API ready for dashboard display
• Rich metadata for file browsers
• MIME type detection for proper file icons

Memory MCP Integration

• File operations can be logged to Memory MCP
• Document metadata stored as memories
• File relationships tracked in knowledge graph

Security

• Path validation prevents directory traversal attacks
• Operations confined to user workspace
• Shareable URLs with expiration times

Persistent Storage

Files are stored in persistent volumes within Kubernetes:

• User workspace isolation
• Automatic backup capabilities
• Volume expansion support
• Cross-pod file access

Future Integrations

Designed for extensibility with:

• OneDrive - Sync files to Microsoft OneDrive
• Google Drive - Backup and sync with Google Drive
• Dropbox - Cross-platform file synchronization
• S3 - Archive and backup to AWS S3
