ls

Lists files and subdirectories in a specified remote directory. Based on the Unix ls command, works across FTP, SFTP, S3, WebDAV, SMB, GIT, NFS, and other configured backends.

cat

Reads and returns the contents of a file at a specific path on the remote storage backend.

pwd

Returns the current working directory path in the remote storage session.

cd

Changes the current working directory so subsequent file operations run relative to a different path on the remote storage.

mv

Moves or renames a file or directory from one path to another on the remote storage backend.

mkdir

Creates a new directory at the specified path on the remote storage backend.

touch

Creates an empty file at the specified path on the remote storage backend.

Frequently Asked Questions

What is Filestash?

Remote Storage Access: SFTP, S3, FTP, SMB, NFS, WebDAV, GIT, FTPS, gcloud, azure blob, sharepoint, etc.

What tools does Filestash provide?

Filestash provides 9 tools including ls, cat, pwd, cd. Each tool can be called by AI agents to perform specific operations.

Is Filestash safe to use?

We cannot tell you that, and nobody scanning at this scale can. What we did in March 2026 was shallow-clone Filestash and run five keyword searches over its source: auth identifiers, CORS configuration, rate-limit identifiers, the dependency manifest against a hardcoded list of 18 known-vulnerable packages, and unguarded eval/exec calls. At least one matched — the specific finding is in the scan report on this page. A text search cannot follow a variable, judge intent, or tell you what a server does once it is running, so "nothing matched" is not "safe". What the scan does and does not cover is written out at /mcp/security.

What are alternatives to Filestash?
