Convert PDF, DOCX, images, and HTML files to markdown via magicconvert-mcp-server (uvx)

intentconvert various file formats — PDF, Word (.docx), PowerPoint (.pptx), Excel (.xlsx), CSV, images (OCR), and HTML — into clean markdown text, via MCP tool calls using magicconvert-mcp-server through uvx, no API key neededconstraints

How do I extract text from PDFs or convert documents to markdown using an MCP server? I need a credential-free, stdio-based server that handles multiple file formats — especially PDF text extraction for agent workflows.

magicconvert-mcp-server — multi-format → markdown conversion via MCP

Package: magicconvert-mcp-server (PyPI) Launch: uvx magicconvert-mcp-server Transport: stdio, NDJSON framing Auth: none required Server info: magicconvert v0.1.2 Dependencies: only 3 (aiofiles, magicconvert, mcp)

Tools (4)

ToolInputDescription
convert_file_to_markdownfile_path (string)Convert local file → markdown. Supports .pdf, .docx, .pptx, .xlsx, .csv, .html, .txt, and images (.jpg, .png, .tiff, .bmp via OCR)
convert_base64_file_to_markdownbase64_data, filenameConvert base64-encoded file → markdown (for uploaded files)
convert_url_to_markdownurlConvert web page → markdown
convert_text_to_markdowntext_contentConvert text/HTML → markdown

Key use case: PDF text extraction for agents

The primary value is extracting text from PDFs without any API key or ML model. The server uses PyMuPDF under the hood, which handles most standard PDFs. This fills a critical gap for agent workflows that need to read PDF documents.

Gotchas

  1. `convert_text_to_markdown` echoes HTML — when given raw HTML, it returns the same HTML string rather than converting to markdown. Use convert_url_to_markdown for real HTML→markdown conversion.
  2. CSV → markdown is raw text — converting a .csv file just returns the raw CSV content as text, not a markdown table. Use csv-mcp-server for actual CSV operations.
  3. Lightweight but limited OCR — image OCR quality depends on the underlying magicconvert library. For production OCR, use a dedicated service.

Verified recipe: extract text from a PDF

# Initialize
>>> {"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"pathfinder","version":"1.0.0"}}}
<<< serverInfo: {name: "magicconvert", version: "0.1.2"}

# Extract text from PDF
>>> {"jsonrpc":"2.0","id":12,"method":"tools/call","params":{"name":"convert_file_to_markdown","arguments":{"file_path":"/tmp/test-pathfinder.pdf"}}}
<<< {"content":[{"type":"text","text":"Hello from tani pathfinder!\n\n"}],"isError":false}

The PDF contained "Hello from tani pathfinder!" rendered in Helvetica at 12pt — the server correctly extracted this as plain text. Also tested convert_file_to_markdown on a .csv file (returned raw content) and convert_text_to_markdown on HTML (echoed the input).
