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
