MCP Pdf Processor

🚀 PDF Processor MCP Server

A Model Context Protocol (MCP) server for processing PDF documents with advanced features including LaTeX equation extraction. This server enables Claude to fetch, process, and extract information from PDF documents, including LaTeX mathematical equations.

🚀 Quick Start

This PDF Processor MCP Server allows you to process PDF documents, enabling Claude to perform operations such as fetching, processing, and extracting information from PDFs, including LaTeX equations.

✨ Features

• PDF fetching from URLs
• Text extraction from PDFs
• LaTeX equation recognition and extraction
• Integration with Claude via MCP

📦 Installation

Standard Installation

pip install -e .

Installing for Claude Desktop/Claude Code

To use this MCP server with Claude Desktop or Claude Code:

1. Install the MCP CLI tools if not already installed:

   pip install "mcp[cli]"
   

2. Install the server using the MCP CLI tool:

   mcp install /path/to/pdf_tool_server.py --with-editable /path/to/mcp_pdf_processor
   

   For example, if you've cloned this repository to ~/mcp_pdf_processor:

   mcp install ~/mcp_pdf_processor/pdf_tool_server.py --with-editable ~/mcp_pdf_processor
   

3. For development with the MCP Inspector:

   mcp dev /path/to/pdf_tool_server.py --with-editable /path/to/mcp_pdf_processor
   

4. In Claude Desktop, you can now use the PDF_TOOLS server in your conversations with these commands:

   /mcp PDF_TOOLS fetch_pdf url=https://example.com/document.pdf
   /mcp PDF_TOOLS process_pdf hash_id=<HASH_ID> extract_latex=true
   /mcp PDF_TOOLS read_processed_pdf filename=<FILENAME>
   

💻 Usage Examples

Basic Usage

python pdf_tool_server.py

Environment Variables

• OUTPUT_DIR: Directory to store processed PDFs (default: llm_output)
• PYTHONPATH: Set to the directory containing the mcp_pdf_processor package

Advanced Usage

When the server is registered, you can ask Claude to:

• "Fetch and analyze the PDF at [URL]"
• "Extract LaTeX equations from the PDF at [URL]"
• "Summarize the content of the PDF at [URL]"

Complete Workflow Example

Here's a complete example workflow for using the PDF processor with Claude Desktop:

# 1. Fetch a PDF without reading it
/mcp PDF_TOOLS fetch_pdf url=https://arxiv.org/pdf/2505.05522

# This returns a hash_id, which you'll use in the next step

# 2. Process the PDF with LaTeX extraction
/mcp PDF_TOOLS process_pdf hash_id=<HASH_ID> extract_latex=true

# This returns a filename for the processed output

# 3. Read the processed content
/mcp PDF_TOOLS read_processed_pdf filename=<FILENAME>

# Now Claude can analyze the PDF content, including any LaTeX equations
