Seafile Server

Author License: MIT

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:

Option	Description	Link
Seafile Cloud	Hosted by Seafile (easiest)	cloud.seafile.com
Docker Install	Self-host with Docker (recommended)	Docker Guide
Manual Install	Self-host on Linux server	Manual Guide
Synology NAS	Run on Synology NAS	Synology Package
UGREEN NAS	Run on UGREEN NAS via Docker	Docker Guide
Raspberry Pi	Self-host on a Pi	Pi Guide

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 MCP server?

Once set up, you can ask Claude things like:

Document Lookups

• "What are my flight details for the Hawaii trip?"
• "When is my car rental pickup?"
• "Find my tax files from 2024"
• "What's in my Immigration folder?"
• "Show me my recent receipts"
• "List all of Mom's travel folders"
• "Find Dad's visa documents"

Organization

• "Create a new folder called '2025 Taxes'"
• "Move the completed trip to Archive"
• "What's in my 'Ideas' folder?"

Quick Search

• "Find all PDFs related to insurance"
• "Which folders were modified this month?"
• "Do I have a copy of my lease agreement?"

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

# Option A: Clone with git
git clone https://github.com/setugk/seafile-mcp.git
cd seafile-mcp

# Option B: Or download and extract the ZIP, then cd into it

Step 2: Create a Virtual Environment

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

# Create the virtual environment
python3 -m venv venv

# Activate it
# On macOS/Linux:
source venv/bin/activate

# On Windows:
venv\Scripts\activate

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

Step 3: Install Dependencies

pip install -r requirements.txt

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)

curl -d "username=YOUR_EMAIL&password=YOUR_PASSWORD" \
     https://YOUR_SEAFILE_SERVER/api2/auth-token/

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:

{"token": "a]1b2c3d4e5f6g7h8i9j0..."}

Copy the token value (without quotes).

Step 5: Configure Your Credentials

# Copy the example config
cp .env.example .env

# Edit .env with your favorite editor
nano .env   # or vim, code, etc.

Fill in your values:

SEAFILE_URL=https://your-seafile-server.com
SEAFILE_TOKEN=your-api-token-here

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

python src/server.py

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 .mcp.json file 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"

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:

source venv/bin/activate
python src/server.py

Security & Privacy

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

Protecting Your Credentials

• Never commit your .env file - It contains your API token
• Secure file permissions - Run chmod 600 .env to restrict access
• Rotate tokens periodically - Generate new tokens and revoke old ones
• Use HTTPS - Always connect to your Seafile server over HTTPS

What Claude Can See

When using this MCP server:

• Claude sees file and folder names when you browse
• Claude sees file contents when you ask to read them
• Conversations are processed by Anthropic's servers

Best practice: Avoid asking Claude to read highly sensitive files (passwords, private keys, financial account numbers).

What Claude Can Do

The MCP server allows Claude to:

• Browse, read, and search files
• Create, rename, move, copy, and delete files/folders

Be careful with destructive commands. Consider using a read-only API token if your Seafile server supports scoped permissions.

Local Machine Security

• The MCP server runs locally with your user permissions
• Anyone with access to your machine could read your .env file
• Use standard device security (lock screen, disk encryption)

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