Basic information

About Python (MCP) Filesystem Server

This is a robust Python-based MCP Filesystem Server. It enables AI models and applications to securely interact with the host system's file directories through a defined set of tools, allowing for operations like reading, writing, moving, and listing files and directories.

Overview

What is Python (MCP) Filesystem Server?

Python (MCP) Filesystem Server is a Python-based Model Context Protocol (MCP) server that enables AI models and applications to securely interact with host file directories via a defined set of tools. It uses the fastmcp library and confines all file operations to a configurable list of allowed directories.

How to use Python (MCP) Filesystem Server?

Clone the repository and initialize with uv pip install -r pyproject.toml. Run python3 main.py -d /path/to/allowed/dir1 /path/to/another/allowed/dir2 [--log-level LEVEL] [--log-file PATH]. The server listens for MCP messages on stdin and responds on stdout. A test script (test_mcp_server.py) is provided to verify functionality.

Key features of Python (MCP) Filesystem Server

Strict confinement to predefined allowed directories.
Tools for reading, writing, editing, moving, and listing files.
Recursive directory tree generation.
Configurable logging with file rotation.
Symlink validation to prevent path escape.

Use cases of Python (MCP) Filesystem Server

Allowing an AI assistant to read and edit source code in a project directory.
Enabling a chatbot to manage user-uploaded files (e.g., drafts, notes).
Providing controlled filesystem access for automated reporting or data processing tools.
Letting an AI model safely list and inspect files within a sandboxed workspace.

Frequently asked questions

What directories can the server access?

Directories are specified at startup via the `-d` or `--directories` argument. The server will only operate within those paths.

What Python version and dependencies are required?

Python 3.8 or higher is required, along with the `fastmcp` library.

How does the server handle symlinks?

Symlink targets are validated to ensure they do not point outside the configured allowed directories, preventing path escape.

What transport protocol does the server use?

The server uses standard input/output (stdin/stdout) for MCP communication, adhering to JSON‑RPC 2.0 messages.

What logging options are available?

Log level can be set via `--log-level` (DEBUG, INFO, WARNING, ERROR; default INFO). An optional `--log-file` writes logs to a rotating file.
