Seafile MCP Server

A Model Context Protocol (MCP) server that connects Claude to your Seafile file storage. This lets you ask Claude to browse, search, read, and manage files on your self-hosted Seafile server using natural language.

What is Seafile?

Seafile is an open-source, self-hosted file sync and share platform - similar to Dropbox or Google Drive, but you control your own data. It's popular for personal use, teams, and enterprises who want privacy and control over their files.

Why Seafile?

• Self-hosted: Your files stay on your own server

• Privacy-focused: No third-party access to your data

• Fast sync: Efficient file synchronization across devices

• Libraries: Organize files into encrypted or unencrypted libraries

• Cross-platform: Apps for Windows, Mac, Linux, iOS, Android

Don't have Seafile yet? Here's how to get started:

Why This MCP Server?

• Direct connection - Connects straight to your Seafile server, no middleman

• Privacy-first - Your data never leaves your infrastructure

• Free & open source - No subscriptions, no vendor lock-in

• Full control - Inspect, modify, and extend the code as needed

• Self-hosted - Runs locally alongside your self-hosted Seafile

What Can You Do With This?

Once set up, you can ask Claude things like:

• "List all my libraries"

• "Show me what's in my Documents folder"

• "Read the contents of notes.txt"

• "Create a new folder called 'Projects'"

• "Move report.pdf to the Archive folder"

• "Search for files containing 'invoice'"

Features

Prerequisites

Before you start, make sure you have:

• Python 3.10 or higher - Check with python3 --version

• A Seafile server - Either self-hosted or a Seafile cloud account

• Claude Desktop app or Claude Code CLI - Where you'll use this MCP server

Installation

Step 1: Clone or Download This Repository

Step 2: Create a Virtual Environment

A virtual environment keeps this project's dependencies isolated from your system Python.

You should see (venv) at the start of your terminal prompt. This means the virtual environment is active.

Step 3: Install Dependencies

This installs:

• mcp - The Model Context Protocol library

• httpx - For making HTTP requests to Seafile

• python-dotenv - For loading configuration from .env

Step 4: Get Your Seafile API Token

You need an API token to authenticate with your Seafile server.

Option A: Using the Seafile Web Interface

1. Log into your Seafile web interface

2. Click your avatar/profile icon in the top right

3. Go to Settings → Web API Auth Token

4. Click Generate Token or copy your existing token

Option B: Using curl (Command Line)

Replace:

• YOUR_EMAIL - Your Seafile login email

• YOUR_PASSWORD - Your Seafile password

• YOUR_SEAFILE_SERVER - Your Seafile server URL (e.g., cloud.seafile.com)

The response will look like:

Copy the token value (without quotes).

Step 5: Configure Your Credentials

Fill in your values:

Important:

• No trailing slash on the URL

• No quotes around values

• Keep this file secret (it's already in .gitignore)

Step 6: Test the Server

If everything is set up correctly, the server will start without errors. Press Ctrl+C to stop it.

Connecting to Claude

Choose the method that matches how you use Claude:

Option A: Claude Desktop App

1. Find your Claude Desktop config file:

   • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

   • Windows: %APPDATA%\Claude\claude_desktop_config.json

   Or in Claude Desktop: Claude menu → Settings → Developer → Edit Config

2. Add the MCP server configuration:

   If the file is empty or doesn't exist, create it with:

   { "mcpServers": { "seafile": { "command": "/FULL/PATH/TO/seafile-mcp/venv/bin/python", "args": ["/FULL/PATH/TO/seafile-mcp/src/server.py"] } } }

   If you already have other MCP servers, add seafile inside the existing mcpServers object.

   Important: Replace /FULL/PATH/TO/ with the actual absolute path to where you cloned this repo.

   Example paths:

   • macOS: /Users/yourname/projects/seafile-mcp/venv/bin/python

   • Windows: C:\\Users\\yourname\\projects\\seafile-mcp\\venv\\Scripts\\python.exe

3. Restart Claude Desktop completely:

   • Quit Claude Desktop (Cmd+Q on Mac, Alt+F4 on Windows)

   • Reopen Claude Desktop

4. Verify it works:

   • Start a new conversation

   • Look for the hammer/tools icon - "seafile" should be listed

   • Ask: "Use the hello tool" or "List my Seafile libraries"

Option B: Claude Code (CLI)

1. Create a in your project directory:

   { "mcpServers": { "seafile": { "command": "/FULL/PATH/TO/seafile-mcp/venv/bin/python", "args": ["/FULL/PATH/TO/seafile-mcp/src/server.py"] } } }

2. Start Claude Code in that directory - it will automatically load the MCP server.

3. Test with: "List my Seafile libraries"

Available Tools

Once connected, Claude has access to these tools:

Troubleshooting

"Server not appearing in Claude Desktop"

• Double-check the paths in your config are absolute paths (start with / on Mac/Linux or C:\ on Windows)

• Make sure you fully restarted Claude Desktop (not just closed the window)

• Check for JSON syntax errors in your config file (missing commas, brackets)

"SEAFILE_URL or SEAFILE_TOKEN not configured"

• Make sure you created the .env file (not just .env.example)

• Make sure the .env file is in the project root directory (same folder as src/)

• Check there are no extra spaces or quotes in your .env values

"Connection error: Could not reach server"

• Verify your Seafile server URL is correct and accessible

• Try opening the URL in a browser

• Check if your server requires VPN access

"Authentication failed" or "401 Unauthorized"

• Your API token may have expired - generate a new one

• Make sure you copied the full token with no extra spaces

"Module not found" errors

• Make sure you're using the Python from the virtual environment in your config

• Run venv/bin/pip list to verify mcp and httpx are installed

Check server logs

Run the server manually to see any errors:

Security

Important: Please read SECURITY.md for full security considerations.

Key points:

• Never commit your - It contains your API token

• API tokens grant full access to your Seafile account - treat them like passwords

• Review the code before running - inspect src/server.py to understand what it does

• Secure file permissions - Run chmod 600 .env to restrict access to your credentials

• Consider token scope - Some Seafile deployments support scoped tokens with limited permissions

Reporting vulnerabilities: See SECURITY.md for responsible disclosure guidelines.
