MoviePilot Downloader Operation

Downloader Operation

Use scripts/mp-downloader.py. The helper reads MoviePilot's local downloader configuration and credentials itself. Never request, print, or pass a host, username, password, API key, Cookie, or arbitrary URL.

Run the bundled copy from the MoviePilot program directory with its project runtime, for example:

cd <MOVIEPILOT_ROOT>
python skills/downloader-operation/scripts/mp-downloader.py instances

The Agent command environment routes python to the project-specific moviepilot-python entry when available and falls back to the project or Docker VENV_PATH Python otherwise. Downloader connections may depend on macOS local-network permissions, so use the provided python command for every operation.

The runtime sets MOVIEPILOT_ROOT for copied skills. If you run a copied script directly from <CONFIG_PATH>/agent/skills/, set that variable to the program directory first; otherwise the helper returns a clear relocation error. Do not use a system python3 when it does not meet MoviePilot's required Python version.

Boundary

• Prefer moviepilot-api for ordinary MoviePilot acquisition workflows, especially site search, download.add, subscriptions, transfer, history, and canonical library checks.
• Use this Skill for downloader-native inspection, diagnosis, advanced task properties, and an explicit request to operate the provider directly.
• tasks.add.direct bypasses MoviePilot download history, site Cookie handling, path selection, duplicate checks, and transfer orchestration. Use it only when the user explicitly wants direct provider submission.
• Paths passed to tasks.location.set and tasks.add.direct are downloader-side paths, not MoviePilot storage paths.
• tasks.location.set is a raw provider operation and does not evaluate MoviePilot media categories. For an existing MoviePilot task, use the Web UI resource-category preview and confirmation flow when the target should come from MoviePilot's download history and resource-directory rules.

Instance And Provider Discovery

Fast path: call directly

Do not routinely call instances or capabilities before an operation. This Skill already contains the full action contract, and the helper performs instance resolution, provider support checks, complete argument validation, and the action in one call invocation.

• If the user or prior context provides the exact client name, pass it with --client and call the action immediately.
• If no client name is known, omit --client. The helper automatically uses the single default downloader, or the only enabled downloader.
• If multiple clients remain ambiguous, the failed call lists every valid client name. Reuse that list for the next direct call; do not add a separate instances call unless the user explicitly asks to inspect instances.
• Do not probe an action with empty or guessed arguments. Compose the complete JSON object from the contract below before calling.

The helper rejects unknown fields and reports all detectable argument errors in one response before connecting to the provider, so correct every reported field together instead of retrying one field at a time.

Optional discovery

List configured instances without secrets:

python skills/downloader-operation/scripts/mp-downloader.py instances

List the actions supported by all providers or one configured client:

python skills/downloader-operation/scripts/mp-downloader.py capabilities
python skills/downloader-operation/scripts/mp-downloader.py capabilities --client "main-qb"

The complete action and argument contract is documented below. Use capabilities only to confirm which documented actions a configured provider supports. For a compact machine-readable copy of one action's same contract:

python skills/downloader-operation/scripts/mp-downloader.py capabilities \
  --client "main-qb" \
  --action tasks.properties.set

Do not inspect the helper source to discover arguments and do not guess a provider-specific action. capabilities is optional and should be used only when the configured provider itself is unknown or support must be diagnosed.

Call Shape

python skills/downloader-operation/scripts/mp-downloader.py call \
  --client "main-qb" \
  --action tasks.list \
  --arguments '{"status":"downloading","limit":20}'

The --arguments value must be one JSON object. Large reads are paged with offset and limit; the default limit is 50 and the maximum is 200.

External MCP Contract

External MCP clients do not receive this SKILL.md and cannot use the hidden execute_command tool. MoviePilot therefore exposes a separate admin-only MCP tool named downloader_operation. Its tools/list inputSchema contains one oneOf branch for every action below, including the function description, supported providers, effect, field types, required/default values, enums, and cross-field rules. The external client should select the matching branch and make one tools/call; it does not need to call a discovery tool first.

MCP call arguments use the same contract without shell quoting:

{
  "client": "main-qb",
  "action": "tasks.properties.set",
  "arguments": {
    "task_id": "exact-provider-hash",
    "download_limit": 2048,
    "upload_limit": 512
  }
}

client may be omitted for the default or only enabled downloader. If multiple instances remain ambiguous, the result lists the valid client names.

Complete Action Contract

This is the complete Downloader Operation action contract. It comes directly from the script ACTIONS registry and matches the external MCP tools/list oneOf branches. A field name ending in * is required. Put every action parameter in the arguments object.

capabilities.list

List supported downloader actions and their complete argument contracts. Effect: safe_read. Providers: qbittorrent, transmission, rtorrent.

• action_name (string): Optional exact action name used to return one capability contract.

instances.list

List configured downloader instances without connection secrets. Effect: safe_read. Providers: qbittorrent, transmission, rtorrent.

• arguments: {}

session.content_layout

Read qBittorrent's default torrent content layout. Effect: safe_read. Providers: qbittorrent.

• arguments: {}

session.details

Read Transmission session configuration and capacity details. Effect: safe_read. Providers: transmission.

• arguments: {}

session.speed_limits.get

session.speed_limits.set

Set global speed limits in KB/s. Effect: reversible_write. Providers: qbittorrent, transmission.

• download_limit (number): Global download limit in KB/s; 0 or omission means unlimited.
• upload_limit (number): Global upload limit in KB/s; 0 or omission means unlimited.

session.stats

Read provider transfer/session statistics. Effect: safe_read. Providers: qbittorrent, transmission, rtorrent.

tasks.add.direct

Submit a magnet, URL, or local torrent file directly to the provider. Effect: external_side_effect. Providers: qbittorrent, transmission, rtorrent.

• torrent_file (boolean; default False): Interpret content as a local torrent-file path.
• paused (boolean; default False): Add the task in a paused state.
• download_dir (string): Provider-side save path.
• tags (string[]): Tags to assign to the new task.
• category (string): qBittorrent category; ignored by other providers.
