• Read text content from local PDF files
• Read text content from PDF URLs
• Error handling for corrupt or invalid PDFs
• Volume mounting for accessing local PDFs
• Auto-detection of PDF encoding
• Standardized JSON output format

1. Clone the repository:

git clone https://github.com/trafflux/pdf-reader-mcp.git
cd pdf-reader-mcp

2. Build the Docker image:

docker build -t mcp/pdf-reader .

To run the server with access to local PDF files:

docker run -i --rm -v /path/to/pdfs:/pdfs mcp/pdf-reader

Replace /path/to/pdfs with the actual path to your PDF files directory.

If not using local PDF files:

docker run -i --rm mcp/pdf-reader

Add to your MCP settings configuration:

{
  "mcpServers": {
    "pdf-reader": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-v",
        "/path/to/pdfs:/pdfs",
        "mcp/pdf-reader"
      ],
      "disabled": false,
      "autoApprove": []
    }
  }
}

Without local file PDF files:

{
  "mcpServers": {
    "pdf-reader": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "mcp/pdf-reader"],
      "disabled": false,
      "autoApprove": []
    }
  }
}

1. read_local_pdf

   • Purpose: Read text content from a local PDF file
   • Input:

     {
       "path": "/pdfs/document.pdf"
     }

   • Output:

     {
       "success": true,
       "data": {
         "text": "Extracted content..."
       }
     }

2. read_pdf_url

   • Purpose: Read text content from a PDF URL
   • Input:

     {
       "url": "https://example.com/document.pdf"
     }

   • Output:

     {
       "success": true,
       "data": {
         "text": "Extracted content..."
       }
     }

The server handles various error cases with clear error messages:

• Invalid or corrupt PDF files
• Missing files
• Failed URL requests
• Permission issues
• Network connectivity problems

Error responses follow the format:

{
  "success": false,
  "error": "Detailed error message"
}

• Python 3.11+
• PyPDF2: PDF parsing and text extraction
• requests: HTTP client for fetching PDFs from URLs
• MCP SDK: Model Context Protocol implementation
