​
What is MCP?

The Model Context Protocol (MCP) is an open standard that lets AI assistants interact with external tools and services. Instead of copying and pasting between your AI assistant and the Ollang dashboard, MCP enables the assistant to call Ollang APIs directly on your behalf.
Ollang MCP is hosted on Cloudflare Workers and supports both SSE and HTTP streaming transports. No local installation required for the remote server.

​
What Can You Do?

With Ollang MCP, your AI assistant can:
  • Upload files — Videos, documents, subtitles, JSON, and DITA files
  • Create translation orders — Subtitles, closed captions, AI dubbing, studio dubbing, and document translation
  • Manage orders — Track status, cancel, rerun, and request human review
  • Run QC evaluations — AI-powered quality checks for accuracy, fluency, tone, and cultural fit
  • Handle revisions — Create, view, and delete revision requests
  • Manage projects — Browse and inspect all uploaded projects
  • Custom instructions — Create reusable translation guidelines
  • Read subtitle files — Parse SRT, VTT, ASS, and SSA formats from URLs

​
