markitdown-mcp

Or using the development script:

python run_server.py

🛠️ Installation Options

🚀 One-Command Install (Recommended)

Install with ALL dependencies in one command:

# Using pipx (recommended)
pipx install git+https://github.com/trsdn/markitdown-mcp.git && \
pipx inject 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 -e git+https://github.com/trsdn/markitdown-mcp.git

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 git+https://github.com/trsdn/markitdown-mcp.git

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

Method 2: Using pip with virtual environment

# Create and activate virtual environment
python -m venv markitdown-env

# 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 markitdown-mcp 'markitdown[all]' openpyxl xlrd pandas pymupdf pdfplumber

Verify Installation

After installation, verify all dependencies are properly installed:

# Test the MCP server
markitdown-mcp --help

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