### Description (declared)

# chuk-mcp-vfs

**MCP server providing virtual filesystem workspaces via the unified namespace architecture.**

## Features

✅ **Unified Architecture** - Built on chuk-artifacts namespace system
✅ **Context-Aware** - Automatic user/session scoping from MCP context
✅ **Storage Scopes** - SESSION (ephemeral), USER (persistent), SANDBOX (shared)
✅ **Pydantic Native** - All requests and responses use Pydantic models
✅ **Async Native** - Fully async/await throughout
✅ **Type Safe** - Enums and constants instead of magic strings
✅ **Multiple Workspaces** - Create and manage isolated virtual filesystems
✅ **Full VFS Operations** - read, write, ls, tree, mkdir, rm, mv, cp, cd, pwd, find, grep
✅ **Checkpoints** - Save and restore filesystem state at any point
✅ **MCP Integration** - Expose all operations as MCP tools for AI agents

## Architecture

```
chuk-mcp-vfs           → Workspace management + VFS tools
    ↓ uses
chuk-artifacts         → Unified namespace architecture
    ↓ manages
Namespaces (WORKSPACE) → Each workspace is a namespace
    ↓ provides
chuk-virtual-fs        → Async VFS with multiple storage providers
    ↓
Storage Provider       → memory, filesystem, sqlite, s3
```

**Key Concepts:**
- **Everything is VFS**: Both blobs and workspaces are VFS-backed via namespaces
- **Scopes**: SESSION (per-conversation), USER (per-user persistent), SANDBOX (shared)
- **Context-Aware**: user_id and session_id automatically from MCP server context
- **Grid Architecture**: All namespaces stored in unified grid structure

## Installation

```bash
# Basic installation
pip install chuk-mcp-vfs

# With FUSE mounting support (Linux/macOS)
pip install chuk-mcp-vfs[mount]

# Development
pip install -e .[dev]
```

## Quick Start

### Running the MCP Server

The server supports two transport modes:

#### 1. STDIO Transport (for Claude Desktop)

```bash
# Default - runs with stdio transport
chuk-mcp-vfs

# Explicitly specify stdio transport
chuk-mcp-vfs --transport stdio

# With d…
