MinerU Open MCP: MCP server, setup and security

What MinerU Open MCP does

According to its repository: “Convert PDFs, Word and PowerPoint files, images and spreadsheets to Markdown via the MinerU document parsing API.”

The Model Context Protocol (MCP) is a standard plug between an AI agent and an outside service: once the server is connected, its tools show up in the agent, which decides when to call them. MinerU Open MCP is listed under Web search and extraction, a category of 159 servers in the directory, where it ranks #19 by stars.

Installing and connecting MinerU Open MCP

Distribution modes declared in the official MCP registry:

• PyPI package (Python, started with uvx or pip)

It works with any MCP-compatible client (Claude Desktop, Claude Code, Cursor, VS Code, Codex and most recent agents). You add one entry to the client's MCP configuration: server name, start command or URL, environment variables. Project language: Python.

The registry lists one secret variable to provide (API key, access token). Keep them in the client's environment variables, never in a shared file or a repository.

Security: what to check

Connecting an MCP server means installing software that talks straight to your agent: it runs with your rights and the model trusts its tool descriptions. The risk therefore depends on what it can touch and how far its code can be trusted.

Points found for MinerU Open MCP:

• Secrets: the server acts with your credentials. Create a dedicated key with minimum rights and an expiry date.

Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.

Project activity and maintenance

Created on March 18, 2026, the opendatalab/MinerU-Ecosystem repository has 229 stars and 18 forks, with 12 open issues. It has more stars than 79% of the servers in the directory. Last change 1 month ago. Version published in the registry: 1.0.20 (April 13, 2026).

Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
