Overview

Node.js server implementing Model Context Protocol (MCP) for filesystem operations. The MCP Filesystem Server provides a simple and direct way to store model context data using local filesystem storage. It's part of the Model Context Protocol (MCP) system, offering a reliable way to persist AI context data using the local filesystem.

Features:

  • Read/write files
  • Create/list/delete directories
  • Move files/directories
  • Search files
  • Get file metadata
  • Built-in file integrity checks
  • Automatic cleanup of temporary files

Note: The server will only allow operations within directories specified via args. 1
