PDF Extraction MCP Server

PDF Extraction MCP Server (Claude Code Fork)

MCP server to extract contents from PDF files, with fixes for Claude Code CLI installation.

This fork includes critical fixes for installing and running the server with Claude Code (the CLI version).

What's Different in This Fork

1. Added __main__.py - Enables the package to be run as a module with python -m pdf_extraction
2. Claude Code specific instructions - Clear installation steps that work with Claude Code CLI
3. Tested installation process - Verified working with claude mcp add command

Components

Tools

The server implements one tool:

• extract-pdf-contents: Extract contents from a local PDF file
  • Takes pdf_path as a required string argument (local file path)
  • Takes pages as an optional string argument (comma-separated page numbers, supports negative indexing like -1 for last page)
  • Supports both PDF text extraction and OCR for scanned documents

Installation for Claude Code CLI

Prerequisites

• Python 3.11 or higher
• pip or conda
• Claude Code CLI installed (claude command)

Step 1: Clone and Install

Step 2: Find the Installed Command

Step 3: Add to Claude Code

Step 4: Use in Claude

Usage Example

Once connected, you can ask Claude to extract PDF contents:

Troubleshooting

Server Not Connecting

1. Make sure you started a NEW Claude session after adding the server
2. Verify the command path is correct: ls -la $(which pdf-extraction)
3. Test the command directly (it should hang waiting for input): pdf-extraction

Module Not Found Errors

If you get Python import errors:

1. Make sure you're using the same Python environment where you installed the package
2. Try using the full Python path: claude mcp add pdf-extraction /path/to/python -m pdf_extraction

Installation Issues

If pip install -e . fails:

1. Make sure you have Python 3.11+: python --version
2. Try creating a fresh virtual environment:
   python -m venv venv source venv/bin/activate # On Windows: venv\Scripts\activate pip install -e .
