FAQ from MCP Filesystem Server

What does MCP Filesystem Server do?

It exposes local filesystem operations (read, write, create, move, search) through the MCP protocol, with strict access control to only allowed directories.

What are the runtime requirements?

Python 3.10 or higher. Installation is recommended via uv, but pip works as well.

How do I restrict which directories the server can access?

Use the --allowed-dir (or -d) option when starting the server. You can specify multiple directories. The server will refuse any operation outside these paths.

Can I run MCP Filesystem Server over HTTP or SSE?

Yes. Run mcp-filesystem-server http --port 8080 --allowed-dir /path for HTTP, or mcp-filesystem-server sse --host 0.0.0.0 --port 3000 for Server‑Sent Events.

Is MCP Filesystem Server secure?

Yes. It performs path validation to prevent directory traversal attacks, checks permissions on every operation, and provides safe error messages that do not leak system information.
