  • OTTASIA is a free, country-aware streaming discovery service for 30 Asian markets and the Asian diaspora in the US, UK, Canada and Australia. It tells you which streaming service carries any movie or show in a given country, what is new on each service, and when theatrical films are expected to reach streaming. It does not host or stream video.

  • **Where can I watch X in Y?** Answer that question in Claude Desktop for **30 Asian and Middle Eastern streaming markets**. OTTASIA's MCP server gives Claude (and any MCP-compatible client) live access to streaming availability across India, Pakistan, Bangladesh, Indonesia, Malaysia, Philippines, Singapore, Thailand, Myanmar, Cambodia, Laos, Brunei, China, Hong Kong, Japan, South Korea, Taiwan, Kazakhstan, Uzbekistan, Turkey, Israel, Lebanon, Jordan, Saudi Arabia, UAE, Kuwait, Qatar, Bahrain, Oman, and Egypt. It wraps [ottasia.com](https://ottasia.com), so the same data that powers our website is one prompt away. No API key, no env vars, no setup. ## Tools - **`where_to_watch(title, country)`** — Find which streaming services carry a specific movie or TV show in a specific country. Example: "Where can I watch Squid Game in Indonesia?" → Netflix, with link to OTTASIA's full title page. - **`whats_new_on(provider, country, limit?)`** — List the latest titles recently added to a streaming service in a country. Example: "What's new on Netflix in India this month?" → 15 fresh titles with overviews. - **`search_titles(q, country, limit?)`** — Multi-result search with disambiguation. Example: "joker" → JOKER GAME (TV 2016), Joker (2019), Joker: Folie à Deux (2024). ## Supported providers (24) Netflix, Amazon Prime Video, Disney+ Hotstar, JioHotstar, JioCinema, Hulu Japan, Wavve, TVING, Viu, Vidio, iQiyi, Shahid, OSN+, STARZPLAY, Hoichoi, Chorki, ZEE5, Sun NXT, Aha, Eros Now, Manorama Max, Shemaroo Me, Crunchyroll, Apple TV+, HBO Max. ## How it works Thin-client architecture: the MCP server wraps three public JSON endpoints on ottasia.com. All TMDB calls, caching (Next.js `unstable_cache`), and per-country provider mapping happen on the OTTASIA backend, so end users install with one command and never touch credentials. ## Links - 📦 npm: [@ottasia/mcp-server](https://www.npmjs.com/package/@ottasia/mcp-server) - 🌐 Website: [ottasia.com](https://ottasia.com) - 💻 Source: [github.com/AIweather-Anurag/ottasia-mcp-server](https://github.com/AIweather-Anurag/ottasia-mcp-server) MIT licensed.
