webshare-api

Node.js/Express proxy that exposes Webshare.cz as protocols *arr apps understand.

Official Webshare HTTP API documentation: https://webshare.cz/apidoc/

Role	Endpoints	Purpose
Torznab indexer	GET /api?t=caps|search|tvsearch|movie	Search → Torznab RSS/XML
Fake torrent	GET /download/:ident	Minimal .torrent whose webseed points at /stream/:ident
Stream	GET /stream/:ident	Fresh Webshare file_link + HTTP 302 to CDN
Fake qBittorrent	/api/v2/*	Download client API; streams the HTTPS file to disk
Debug	GET /resolve/:ident	JSON with the resolved CDN URL
MCP server	POST /mcp (Streamable HTTP)	Tools for AI agents: search, resolve links, login check

Webshare download links expire after roughly ten minutes, so the torrent never embeds a CDN URL—only a path on this service that resolves a fresh link at fetch time.

Configuration

Environment variables (required unless noted):

Variable	Default	Description
WEBSHARE_USERNAME	—	Webshare username or email
WEBSHARE_PASSWORD	—	Webshare password (plain; hashed client-side)
PORT	3001	HTTP listen port
BASE_URL	http://localhost:$PORT	Public base URL Sonarr must reach (use the Compose service hostname when linking containers)
DOWNLOAD_PATH	/downloads/webshare	Where the fake qBittorrent writes files
MEDIA_ROOT	/data	Media root (used for path reporting)
MAX_CONCURRENT_DOWNLOADS	2	Parallel stream downloads
SONARR_URL	http://sonarr:8989	Optional; Sonarr base URL
SONARR_API_KEY	(empty)	Optional; enables periodic missing-episode search
SONARR_SEARCH_INTERVAL_HOURS	2	Interval for that search
DOWNLOAD_HOST_PATH	./data/webshare	Host path mounted at DOWNLOAD_PATH in Compose
MCP_ENABLED	true	Set to 0/false to disable the MCP HTTP endpoint
MCP_PATH	/mcp	HTTP path for the Streamable HTTP MCP endpoint

Copy .env.example and fill in credentials. Do not commit a filled .env.

Run with Compose

cp .env.example .env
# set WEBSHARE_USERNAME and WEBSHARE_PASSWORD
docker compose up -d --build

See compose.yaml. Override ports, BASE_URL, Sonarr settings, and volume mounts via .env as needed.

Run without Compose

npm install
export WEBSHARE_USERNAME=...
export WEBSHARE_PASSWORD=...
npm start

Sonarr / Radarr

1. Indexer (Torznab): http://<host>:3001/api
2. Download client (qBittorrent): host/port of this service; any username/password (login accepts all).

When both run on the same Compose network, use the service name, e.g. http://webshare-api:3001.

Sonarr hands .torrent files to the fake qBittorrent API. This service extracts the webseed, streams the file into DOWNLOAD_PATH, and reports progress via /api/v2/torrents/*.

MCP (AI agents)

Exposes Webshare to MCP-compatible clients over Streamable HTTP (not stdio).

With npm start (or Compose), MCP is available on the same process/port:

POST http://<host>:3001/mcp

Optional MCP-only process (no Torznab/qBittorrent):

export WEBSHARE_USERNAME=...
export WEBSHARE_PASSWORD=...
npm run mcp   # listens on PORT, serves POST /mcp

Tools

Tool	Description
webshare_search	Search files (query, optional limit / offset / sort / category)
webshare_get_link	Resolve a temporary CDN URL for a file ident
webshare_login_check	Verify credentials against the Webshare API

Client configuration example

HTTP / Streamable HTTP (preferred):

[mcp_servers.webshare]
url = "http://127.0.0.1:3001/mcp"

grok mcp add --transport http webshare http://127.0.0.1:3001/mcp

Credentials stay on the server process (WEBSHARE_* env); clients only need the URL.

The transport is stateless Streamable HTTP (POST only).
