Overview

The mcp-filesystem-server is a Go server that implements the Model Context Protocol (MCP) for secure filesystem operations. It provides access to local files and directories while enforcing security measures to prevent directory traversal attacks. The server supports various file operations such as reading, writing, copying, moving, and deleting files, as well as directory operations like listing, creating, and searching. It also features symlink resolution with security checks, MIME type detection, and size limits for inline content and base64 encoding. The mcp-filesystem-server is designed to provide secure access to specified directories. Its features include path validation, secure access to local filesystem, and support for text, binary, and image files. The server can be used for various use cases that require secure filesystem access, such as data processing, file management, and content delivery. To get started, users can follow the installation instructions provided in the repository.

Q&A

What are the integration requirements?

You need a Go runtime to install and run the server, and familiarity with the Model Context Protocol (MCP) to interact with its API; otherwise standard HTTP/MCP clients can communicate with it.
