What is Readonly Filesystem MCP Server?

This server provides secure, readonly access to your filesystem through the Model Context Protocol (MCP). It allows authorized applications to read files and directories without modification capabilities, ensuring data safety.

How to use this server?

Configure the server through Claude Desktop by specifying allowed directories. The server will then provide readonly access to these locations through standardized MCP operations.

Use Cases

Ideal for document analysis tools, code review assistants, or any application that needs secure filesystem access without write permissions.

Key Features

File ReadingRead complete or partial file contents with line number support
Batch File ReadingRead multiple files simultaneously with fault tolerance
Directory NavigationList directory contents with clear file/folder distinction
Advanced SearchRecursive file search with pattern matching and exclusions
File MetadataAccess detailed file information including timestamps and permissions

Pros and Cons

Advantages
Enhanced security through readonly access
Precise control over accessible directories
Supports both individual and batch operations
Case-insensitive search for user convenience
Limitations
No file modification capabilities (by design)
Limited to UTF-8 encoded text files
Requires explicit directory whitelisting

Setup Guide

Install the ServerEnsure Node.js is installed, then add the server to your Claude Desktop configuration
Configure AccessSpecify which directories should be accessible in your configuration file
Launch Claude DesktopStart your application with the new configuration to enable filesystem access

Practical Examples
