📄 MarkItDown MCP Server

A powerful Model Context Protocol (MCP) server that converts 29+ file formats to clean, structured Markdown using Microsoft's MarkItDown library.

[!IMPORTANT] This is not Microsoft's official markitdown-mcp package. This is an independent community project published on PyPI as trsdn-markitdown-mcp. It uses Microsoft's markitdown library as a dependency, but it is developed and maintained separately from markitdown-mcp by Microsoft.

• PyPI distribution name: trsdn-markitdown-mcp
• Python import name: markitdown_mcp
• CLI command: markitdown-mcp (alias: trsdn-markitdown-mcp)

🔥 Perfect for Claude Desktop, MCP clients, and AI workflows!

✨ Features

• 🔌 MCP Protocol: Seamless integration with Claude Desktop and MCP clients
• 📁 29+ File Formats: PDFs, Office docs, images, audio, archives, and more
• 🔍 Image Metadata: Extract EXIF metadata from images (JPG, PNG, GIF, etc.)
• 🎵 Speech Recognition: Convert audio to text with speech transcription (MP3, WAV)*

*Requires markitdown[all] installation for full functionality

Installation

Published on PyPI as trsdn-markitdown-mcp — not to be confused with Microsoft's markitdown-mcp.

Option 1: Install from PyPI (Recommended)

# Isolated install with pipx
pipx install trsdn-markitdown-mcp

# Or with pip
pip install trsdn-markitdown-mcp

# Or run without installing (uv)
uvx trsdn-markitdown-mcp

Option 2: Install from source (development)

git clone https://github.com/trsdn/markitdown-mcp.git
cd markitdown-mcp
pip install -e ".[all]"

Option 3: Direct usage from a checkout

cd markitdown-mcp
python -m venv venv && source venv/bin/activate
pip install -r requirements.txt

Quick Start

MCP Server Mode (Recommended)

After installation:

# Start the MCP server (for use with MCP clients)
markitdown-mcp

# Equivalent alternatives
trsdn-markitdown-mcp
python -m markitdown_mcp

🛠️ Installation Options

🚀 One-Command Install (Recommended)

Install with ALL dependencies in one command:

# Using pipx (recommended)
pipx install trsdn-markitdown-mcp && \
pipx inject trsdn-markitdown-mcp 'markitdown[all]' openpyxl xlrd pandas pymupdf pdfplumber pytesseract pydub speechrecognition

# Or download and run the install script
curl -sSL https://raw.githubusercontent.com/trsdn/markitdown-mcp/main/scripts/install-all-deps.sh | bash

Quick Install (Basic Features Only)

pip install trsdn-markitdown-mcp

Complete Install with All Dependencies (Step by Step)

To ensure all file formats are supported, use one of these methods:

Method 1: Using pipx (Recommended)

# Install the MCP server
pipx install trsdn-markitdown-mcp

# Install all required dependencies for full functionality
pipx inject trsdn-markitdown-mcp 'markitdown[all]'         # PDF, OCR, Speech
pipx inject trsdn-markitdown-mcp openpyxl xlrd pandas      # Excel support
pipx inject trsdn-markitdown-mcp pymupdf pdfplumber        # Advanced PDF

Method 2: Using pip with virtual environment

# Create and activate virtual environment
python -m venv markitdown-env
source markitdown-env/bin/activate  # On Windows: markitdown-env\Scripts\activate

# Install with all dependencies in one command
git clone https://github.com/trsdn/markitdown-mcp.git
cd markitdown-mcp
pip install -e ".[all]"  # This installs everything!

Method 3: For Claude Desktop with existing installation

If you already have the MCP server installed but some formats aren't working:

# Find your installation
which markitdown-mcp  # Shows path like /Users/you/.local/bin/markitdown-mcp

# Inject missing dependencies
pipx inject trsdn-markitdown-mcp 'markitdown[all]' openpyxl xlrd pandas pymupdf pdfplumber

Verify Installation

After installation, verify the server responds to MCP requests:

# Ask the server for its tool list over stdio (JSON-RPC)
echo '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}' | markitdown-mcp

# For pipx installations, check injected packages
pipx list --include-injected

🔧 Claude Desktop Configuration

Add this to your Claude Desktop claude_desktop_config.json:

{
  "mcpServers": {
    "markitdown": {
      "command": "markitdown-mcp",
      "args": []
    }
  }
}

Prefer running it without a permanent install? Use uvx (the package name is trsdn-markitdown-mcp, the command is markitdown-mcp):

{
  "mcpServers": {
    "markitdown": {
      "command": "uvx",
      "args": ["trsdn-markitdown-mcp"]
    }
  }
}

Config file locations:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

💡 Usage Examples

🔍 Troubleshooting

Missing Dependencies Errors

If you see errors like:

• PdfConverter threw MissingDependencyException
• XlsxConverter threw MissingDependencyException
• PptxConverter threw BadZipFile

This means some optional dependencies are missing. Follow the Complete Install instructions above.

Unicode Errors with .md Files

Some Markdown files with special characters may fail with UnicodeDecodeError. This is a known limitation in the MarkItDown library.

Installation Issues

• "externally-managed-environment" error: Use pipx instead of pip
• Permission denied: Never use sudo with pip; use pipx or virtual environments
• Command not found: Make sure ~/.local/bin is in your PATH

See KNOWN_ISSUES.md for more details.

Configuration

No special configuration required. The tool uses the MarkItDown library for document conversion.
