:magnet: qBittorrent MCP Server (Rust) :robot:

[!WARNING] This project is currently in active development (v0.3.9) and is not production-ready. Features may change, and breaking changes may occur without notice.

A Model Context Protocol (MCP) server for qBittorrent, written in Rust. This tool empowers AI agents to interact with and manage your qBittorrent instance using natural language.

:sparkles: Features

• :globe_with_meridians: Search: Search for torrents using qBittorrent's built-in search engine plugins.
• :card_file_box: Torrent Management:
  • Manage multiple qBittorrent instances simultaneously.
  • List all torrents with status, progress, and speed.
  • Add torrents via Magnet URIs or HTTP URLs.
  • Unified Control: Perform actions like pause, resume, reannounce, set category, and add tags via a single manage_torrents tool.
• :mag: Torrent Inspection:
  • Consolidated Inspection: Retrieve properties, files, and trackers in a single call via inspect_torrent.
  • Deep file listing and tracker status monitoring.
• :traffic_light: Global Control:
  • System Health: Monitor global speeds, data usage, and limits via a unified get_system_info tool.
  • Ban peers and update application preferences.
• :label: Categories & Tags: Organize torrents using categories and tags with simplified management tools.
• :mega: Proactive Notifications: Receive real-time notifications when downloads finish (powered by the Sync API).
• :broom: Maintenance Macros:
  • cleanup_completed: Auto-remove torrents based on seeding ratio or age.
  • mass_rename: Bulk rename files within torrents using Regex.
  • find_duplicates: Identify redundant downloads by name.
• :bulb: Troubleshooting Prompts: Consolidated troubleshoot_torrent prompt for guided workflows.
• :sleeping: Lazy Mode: Reduce token usage by hiding advanced tools until explicitly requested.
• :gear: Configuration: TOML, YAML, JSON, or Environment Variables.
• :rocket: Transports: Stdio (default) and HTTP (SSE with optional token auth).
• :books: Resources: Scoped resources for all instances (e.g., qbittorrent://seedbox/torrents).

:hammer_and_wrench: Available Tools

The server exposes the following tools to the LLM, categorized by functionality:

:computer: Usage

Stdio Mode (Default)

Use with an MCP client (e.g., Claude Desktop, Zed, or another MCP-compliant tool).

Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "qbittorrent": {
      "command": "/path/to/qbittorrent-mcp-rs",
      "args": [
        "--qbittorrent-host", "localhost",
        "--qbittorrent-port", "8080",
        "--qbittorrent-username", "admin",
        "--qbittorrent-password", "adminadmin"
      ]
    }
  }
}

HTTP Mode

./qbittorrent-mcp-rs --server-mode http

Server will listen on port 3000.

• SSE Endpoint: http://localhost:3000/sse
• Message Endpoint: http://localhost:3000/message

:hammer_and_wrench: Development

Code Coverage

To generate local code coverage reports, ensure you have cargo-llvm-cov installed:

cargo install cargo-llvm-cov

Run the following command to execute tests and generate a console summary along with a lcov.info file:

task coverage

The lcov.info file is compatible with IDE extensions like VS Code Coverage Gutters.

Reporting to Coveralls.io

To upload coverage data to Coveralls.io, set your repository token and run the upload task:

export COVERALLS_REPO_TOKEN=your_token_here
task coverage:upload

Release Management

This project includes a gemini-cli command to help generate GitHub release summaries based on your local git log.

# Summarize changes between the latest two tags (automatic)
gemini release:summary

# Summarize changes for a specific range or tag
gemini release:summary --range v0.3.2..v0.3.3

Secrets Management

The project uses SOPS for encrypting sensitive files like .env.

• Encrypt: task encrypt (requires .env)
• Decrypt: task decrypt (requires .env.enc)

:mag: Troubleshooting

Connection & Authentication Issues

• 401 Unauthorized: Ensure your username and password are correct. If running qBittorrent 4.6.1+ or 5.x, ensure WebUI\HostHeaderValidation=false is set in your qBittorrent.conf if you are accessing it via a custom hostname or reverse proxy.
• CSRF Protection: If you encounter 403 Forbidden errors during login, ensure WebUI\CSRFProtection=false is set in your configuration, or that the server's Origin and Referer headers (
