Overview

What is Upstage MCP Server?

The Upstage MCP Server is a Model Context Protocol (MCP) server that bridges AI assistants with Upstage AI’s document processing APIs, enabling content extraction and structuring from PDFs, images, and Office files. It is designed for developers and users who want AI models like Claude to parse and extract information from documents.

How to use Upstage MCP Server?

Install using uv (recommended) or pip, then configure Claude Desktop by adding the server entry to claude_desktop_config.json with your UPSTAGE_API_KEY. After restarting Claude, use the parse_document tool to extract structured content or extract_information to retrieve specific data points from a document.
