The LILT MCP (Model-Context Protocol) server integrates with LILT Enterprise APIs to provide translation capabilities within Anthropic’s Claude or other platforms that support hosting MCP servers. This server exposes a set of tools that allow Claude or other MCP server hosts to perform actions such as:
  • Translating text instantly
  • Uploading files for translation
  • Creating verified translation jobs
  • Requesting translation quotes
  • Downloading translated files
  • Checking job status
