Equip Claude Desktop, Cursor, Antigravity IDE, or any MCP-compatible agent to automatically translate documents with layout preservation. Add the following config to your claude_desktop_config.json or MCP configuration file:

{
  "mcpServers": {
    "pdf-language-translator": {
      "command": "npx",
      "args": ["-y", "pdf-language-translator-mcp"],
