Review any command before running it. Package names and URLs come from the server's own registry entry.

Package (npm 2.5.0)

npx -y @j0hanz/[email protected]

Or add to your MCP client config:

{
  "mcpServers": {
    "filesystem-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@j0hanz/[email protected]"
      ],
      "env": {
        "FS_ALLOWED_DIRS": "<YOUR_VALUE>"
      }
    }
  }
}

FS_ALLOWED_DIRS — Allowed directories; ':'-separated on Unix, ';'-separated on Windows. Alternative to positional arguments.

This server takes extra arguments — see its repository.
