Pdf4vllm MCP Server

pdf4vllm

PDF reading MCP server optimized for vision LLMs.

문제

해결

pdf4vllm은 PDF가 지저분하다고 가정합니다.

• 텍스트 손상 자동 감지 → 이미지로 자동 전환
• 읽기 순서 보존 (텍스트 → 표 → 이미지 블록 순서대로)
• 페이지 제한으로 컨텍스트 오버플로우 방지
• 불필요한 이미지 자동 필터링 (로고, 선, 헤더/푸터)

설치

pip install pdf4vllm-mcp
# 또는
uvx pdf4vllm-mcp

Claude Desktop 설정

git clone https://github.com/PyJudge/pdf4vllm-mcp.git
cd pdf4vllm-mcp
python scripts/install_mcp.py

또는 직접 설정 (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "pdf4vllm": {
      "command": "/python/경로",
      "args": ["/pdf4vllm-mcp/경로/src/server.py"]
    }
  }
}

Problem

Solution

pdf4vllm assumes PDFs are messy.

• Auto-detects text corruption → switches to image automatically
• Preserves reading order (text → table → image blocks in sequence)
• Page limits prevent context overflow
• Filters unnecessary images (logos, lines, headers/footers)

Claude Desktop Setup

git clone https://github.com/PyJudge/pdf4vllm-mcp.git
cd pdf4vllm-mcp
python scripts/install_mcp.py

Or manually edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "pdf4vllm": {
      "command": "/path/to/python",
      "args": ["/path/to/pdf4vllm-mcp/src/server.py"]
    }
  }
}

Claude Code Setup

Create .mcp.json in your project:

{
  "mcpServers": {
    "pdf4vllm": {
      "command": "uvx",
      "args": ["pdf4vllm-mcp"]
    }
  }
}

        {"type": "table", "content": "| A | B |"},
        {"type": "image", "content": "[IMAGE_0]"}
      ]
