What is the Transmission MCP server?

Most file and storage access work still happens through a UI a human drives. Transmission MCP server moves it into the conversation instead. A simple MCP server for controlling your Transmission torrent daemon. Supports both direct connection and SOCKS5 proxy for remote access.

The tools it exposes

The server publishes 5 tools. What each one is for:

  • add_torrent — Add a new torrent via magnet link or URL. - magnet_or_url: Magnet link or torrent file URL - download_dir: Optional custom download directory -
  • control_torrent — Start, stop, or remove torrents. - action: "start", "stop", or "remove" - torrent_ids: Array of torrent IDs - delete_data: Whether to delete local
  • get_free_space — Check available disk space for downloads. - path: Optional directory path to check - use_socks5: Use SOCKS5 proxy for this request (default: false)
  • list_torrents — List all torrents with their status, progress, and download directories. - use_socks5: Use SOCKS5 proxy for this request (default: false)
  • get_session_info — Get information about the Transmission daemon session, including version, settings, and statistics. - use_socks5: Use SOCKS5 proxy for this request

Getting it running

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.

What it needs from you

Configuration is passed through the environment: TRANSMISSION_HOST, TRANSMISSION_PORT, TRANSMISSION_USERNAME, TRANSMISSION_PASSWORD, USE_SOCKS5, SOCKS5_HOST. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

How it compares

This sits in the file and storage access group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Transmission's toolset — add_torrent, control_torrent, get_free_space and 2 more — is a fair guide to whether it matches your workflow. It is maintained by v-odoo-testing; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Things to watch

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Frequently asked questions

It connects Transmission to MCP-compatible AI assistants such as Claude and Cursor, exposing 5 tools (add_torrent, control_torrent, get_free_space, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Transmission directly.
