Guide

Filesystem server setup

Filesystem access is one of the fastest ways to expand blast radius. Keep the allowed surface narrow and obvious.

Section 1

Scope first

Review which directories the server can read or write and whether that scope is still justified after the first demo. �Works� is not the same as �safe enough for routine use.�

Section 2

Safer review posture

  • limit the path set to what the task actually needs
  • avoid broad environment forwarding when local files can already reveal enough
  • revisit scope after the initial setup so demo permissions do not become permanent
Section 3

Where the scanner helps

MCP Preflight can surface broad local scope and nearby setup risk, but you still need a human decision about what the fileserver should be allowed to touch at all.
