What Filestash does
According to its repository: “Remote storage access: SFTP, S3, FTP, SMB, NFS, WebDAV, Git, FTPS, Google Cloud, Azure Blob, SharePoint and more.”
The Model Context Protocol (MCP) is a standard plug between an AI agent and an outside service: once the server is connected, its tools show up in the agent, which decides when to call them. Filestash is listed under Files and documents, a category of 55 servers in the directory, where it ranks #3 by stars.
Topics declared by the repository: ftp, sftp, s3, webdav, git, nfs.
Installing and connecting Filestash
No package or remote server is declared in the official MCP registry: you install it from source, following the repository README.
It works with any MCP-compatible client (Claude Desktop, Claude Code, Cursor, VS Code, Codex and most recent agents). You add one entry to the client's MCP configuration: server name, start command or URL, environment variables. Project language: Go.
Security: what to check
Connecting an MCP server means installing software that talks straight to your agent: it runs with your rights and the model trusts its tool descriptions. The risk therefore depends on what it can touch and how far its code can be trusted.
Points found for Filestash:
- System access: the Files and documents category gives the agent control over files, a terminal, code or a browser. A booby-trapped instruction in content the agent reads (prompt injection) can then turn into an action.
Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.
Project activity and maintenance
Created on June 13, 2017, the mickael-kerjean/filestash repository has 14,824 stars and 1,014 forks, with 96 open issues. It is one of the most starred servers in the directory. It received changes this month.
Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
