Introduction

Welcome to the LILT Model Context Protocol (MCP) Server! By connecting your favorite AI clients—like Claude or ChatGPT— to LILT, you can bridge the gap between advanced LLM reasoning and LILT’s enterprise-grade translation capabilities. Instead of constantly switching tabs, you can now translate text and files, manage translation jobs, and access your organization’s custom data sources directly within your active chat sessions. Whether you’re using Claude Desktop/ChatGPT Enterprise for a seamless UI experience or Claude Code to stay in your terminal, you can connect and start prompting in just a few minutes. The LILT MCP (Model-Context Protocol) server integrates with LILT Enterprise APIs to provide translation capabilities within any harness that supports hosting MCP servers.

Connecting Your Clients to LILT Enterprise MCP

​
1. Global Setup Overview

Regardless of which AI client you prefer, the core integration workflow always follows these four essential steps:
  1. Register the Server URL: Client Configuration.
    1. Add the secure LILT MCP endpoint to your client: https://mcp-enterprise.lilt.com/mcp
  2. Authenticate Your Account: OAuth Flow.
    1. Follow your client’s prompt to sign in with your enterprise LILT credentials to securely link your workspace permissions.
  3. Initialize the Session: Fresh Start.
    1. Always start a new chat session immediately after installation to force the LLM to scan and register the new LILT tools.
  4. Target Your Prompts: Routing.
    1. Explicitly include the word “LILT” in your initial prompts (e.g., “Ask LILT to…”) so the model knows to route the task to the MCP server.
