Integrations

  • Provides containerization for the filesystem MCP server, allowing secure access to specified directories through Docker mounts. The README includes Docker configuration examples.

  • The MCP server is implemented in Node.js, providing filesystem access capabilities through a standardized protocol.

Filesystem MCP Server

Node.js server implementing Model Context Protocol (MCP) for filesystem operations.

Features

  • Read/write files
  • Create/list/delete directories
  • Move files/directories
  • Search files
  • Get file metadata

Note: The server will only allow operations within directories specified via args.

API

Resources

  • file://system: File system operations interface

Tools

  • read_file
    • Read complete contents of a file
    • Input: path (string)
    • Reads complete file contents with UTF-8 encoding
  • read_multiple_files
    • Read multiple files simultaneously
    • Input: paths (string[])
    • Failed reads won't stop the entire operation
  • write_file
    • Create new file or overwrite existing (exercise caution with this)
    • Inputs:
      • path (string): File location
      • content (string): File content
  • edit_file
    • Make selective edits using advanced pattern matching and formatting
    • Features:
      • Line-based and multi-line content matching
      • Whitespace normalization with indentation preservation
      • Multiple simultaneous edits with correct positioning
      • Indentation style detection and preservation
      • Git-style diff output with context
      • Preview changes with dry run mode
    • Inputs:
      • path (string): File to edit
      • edits (array): List of edit operations
        • oldText (string): Text to search for (can be substring)
        • newText (string): Text to replace with
      • dryRun (boolean): Preview changes without applying (default: false)
    • Returns detailed diff and match information for dry runs, otherwise applies changes
    • Best Practice: Always use dryRun first to preview changes before applying them
  • create_directory
    • Create new directory or ensure it exists
    • Input: path (string)
    • Creates parent directories if needed
    • Succeeds silently if directory exists
  • list_directory
    • List directory contents with [FILE] or [DIR] prefixes
    • Input: path (string)
  • move_file
    • Move or rename files and directories
    • Inputs:
      • source (string)
      • destination (string)
    • Fails if destination exists
  • search_files
    • Recursively search for files/directories
    • Inputs:
      • path (string): Starting directory
      • pattern (string): Search pattern
      • excludePatterns (string[]): Exclude any patterns. Glob formats are supported.
    • Case-insensitive matching
    • Returns full paths to matches
  • get_file_info
    • Get detailed file/directory metadata
    • Input: path (string)
    • Returns:
      • Size
      • Creation time
      • Modified time
      • Access time
      • Type (file/directory)
      • Permissions
  • list_allowed_directories
    • List all directories the server is allowed to access
    • No input required
    • Returns:
      • Directories that this server can read/write from

Usage with Claude Desktop

Add this to your claude_desktop_config.json:

Note: you can provide sandboxed directories to the server by mounting them to /projects. Adding the ro flag will make the directory readonly by the server.

Docker

Note: all directories must be mounted to /projects by default.

{ "mcpServers": { "filesystem": { "command": "docker", "args": [ "run", "-i", "--rm", "--mount", "type=bind,src=/Users/username/Desktop,dst=/projects/Desktop", "--mount", "type=bind,src=/path/to/other/allowed/dir,dst=/projects/other/allowed/dir,ro", "--mount", "type=bind,src=/path/to/file.txt,dst=/projects/path/to/file.txt", "mcp/filesystem", "/projects" ] } } }

NPX

{ "mcpServers": { "filesystem": { "command": "npx", "args": [ "-y", "@modelcontextprotocol/server-filesystem", "/Users/username/Desktop", "/path/to/other/allowed/dir" ] } } }

Usage with VS Code

For quick installation, click the installation buttons below...

For manual installation, add the following JSON block to your User Settings (JSON) file in VS Code. You can do this by pressing Ctrl + Shift + P and typing Preferences: Open Settings (JSON).

Optionally, you can add it to a file called .vscode/mcp.json in your workspace. This will allow you to share the configuration with others.

Note that the mcp key is not needed in the .vscode/mcp.json file.

You can provide sandboxed directories to the server by mounting them to /projects. Adding the ro flag will make the directory readonly by the server.

Docker

Note: all directories must be mounted to /projects by default.

{ "mcp": { "servers": { "filesystem": { "command": "docker", "args": [ "run", "-i", "--rm", "--mount", "type=bind,src=${workspaceFolder},dst=/projects/workspace", "mcp/filesystem", "/projects" ] } } } }

NPX

{ "mcp": { "servers": { "filesystem": { "command": "npx", "args": [ "-y", "@modelcontextprotocol/server-filesystem", "${workspaceFolder}" ] } } } }

Build

Docker build:

docker build -t mcp/filesystem -f src/filesystem/Dockerfile .
