Point this at one or more folders and your assistant can read, write, copy, move, rename and delete files inside them, and only inside them. It can show a folder as a tree, find files by name, hunt for a phrase across a whole directory, and do find-and-replace inside a document. Paths are checked so it cannot wander outside the folders you named. It is written in Go and installs from source or as a container image, so setup is technical.

mcp-filesystem-server FAQ

Can it touch files outside the folders I choose?
No. You list the allowed folders when you start it, and it refuses anything outside them.
Can I use this to search my documents for a phrase?
Yes. It can look through file contents across a whole folder tree and report every match.
Which apps does it work in?
Any app that accepts MCP servers. The readme shows the generic settings snippet that most of them use.
Is a paid key needed?
No. Everything happens on your own computer, with no account and no key.
How hard is setup?
Technical. You install it with the Go toolchain or run it as a container, then add a snippet to your app's settings.
Can it delete things?
Yes, including whole folders when asked, so be deliberate about which directories you hand it.
Does it handle images?
It detects file types and supports text, binary and image files, with size limits on what it sends back inline.
