flexberry-markitdown-mcp 2.0.0

MCP server for converting files to Markdown (via MarkItDown) and Markdown to PDF

Flexberry MarkItDown MCP Server

MCP server for bidirectional document conversion:

• Any format → Markdown (via Microsoft MarkItDown)
• Markdown → PDF (via Playwright / headless Chromium — same approach as vscode-markdown-pdf)

Powered by:

• Microsoft MarkItDown — any-format to Markdown conversion
• Approach from vscode-markdown-pdf — PDF generation via headless Chromium

Installation — one command

pip install flexberry-markitdown-mcp

That's it! On first convert_to_pdf call, Chromium is auto-downloaded (same as vscode-markdown-pdf).

Optional extras

# Lightweight backend without browser (no JS rendering)
pip install flexberry-markitdown-mcp[weasyprint]

# For development
pip install flexberry-markitdown-mcp[dev]

Logging

Server logs are saved to:

• Linux: ~/.flexberry-markitdown-mcp/server.log
• Windows: C:\Users\<user>\.flexberry-markitdown-mcp\server.log

Troubleshooting

pip install flexberry-markitdown-mcp

Error: "MCP module not found"

pip install flexberry-markitdown-mcp

Cyrillic issues in Windows

Ensure UTF-8 encoding in terminal. Server automatically sets UTF-8 for stdin/stdout/stderr.
