Upstage MCP Server

An MCP server for Upstage document parsing and information extraction. Exposed over MCP by the upstage mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

The Upstage MCP Server provides a robust bridge between AI assistants and Upstage AI’s powerful document processing APIs. This server enables AI models—such as Claude—to effortlessly extract and structure content from various document types including PDFs, images, and Office files. The package supports multiple formats and comes with seamless integration options for Claude Desktop.

• Document Digitization: — Extract structured content from documents while preserving layout
• Information Extraction: — Retrieve specific data points using intelligent, customizable schemas
• Multi-format Support: — Handles JPEG, PNG, BMP, PDF, TIFF, HEIC, DOCX, PPTX, and XLSX
• Claude Desktop Integration: — Effortlessly connect with Claude and other MCP clients

Adding it to your client

Command on PyPI is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Its toolset

Everything the assistant can do here goes through one of these:

• Description — ** Processes documents and extracts content while preserving structure
• Parameter — **
• Parameters — **

Configuration

You will need one environment variable: UPSTAGE_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Before using this server, ensure you have the following: 1. Upstage API Key: Obtain your API key from Upstage API. 2. Python 3.10+: The server requires Python version 3.10 or higher. 3. The MCP server relies upon Astral UV to run, please install

Caveats

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the upstage mcp server does with a few real requests.

When to reach for it

Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Upstage's toolset — Description, Parameter, Parameters — is a fair guide to whether it matches your workflow.
