Documentation Overview

pdf4vllm

PDF reading MCP server optimized for vision LLMs.

한국어

문제

방식	문제점
텍스트 추출	인코딩 깨짐 → 쓰레기 출력, 이미지-텍스트 순서 뒤섞임
이미지 변환	토큰 폭발 (특히 페이지 많을 때)

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

Terminal

pip install pdf4vllm-mcp
# 또는
uvx pdf4vllm-mcp

Claude Desktop 설정

bash

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):

config.json

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

도구

도구	설명
`list_pdfs`	PDF 파일 찾기 (glob 패턴 `name_pattern` 지원)
`read_pdf`	PDF 내용 블록으로 추출
`grep_pdf`	PDF 내 텍스트 검색 (`pdfgrep` 설치 필요)

추출 모드

모드	설명
`auto` (기본)	텍스트 추출 시도 → 손상 감지 시 이미지로 전환
`text_only`	텍스트/표만 추출, 이미지 없음
`image_only`	페이지를 이미지로만 렌더링

Problem

Approach	Issue
Text extraction	Encoding corruption → garbage output, mixed text-image ordering
Image conversion	Token explosion (especially with many pages)

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

bash

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:

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:

config.json

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

Tools

Tool	Description
`list_pdfs`	Find PDF files with glob filtering (`name_pattern`)
`read_pdf`	Extract PDF content as ordered blocks
`grep_pdf`	Search text in PDFs using pdfgrep (requires `pdfgrep` installed)

Extraction Modes

Mode	Description
`auto` (default)	Try text extraction → switch to image if corrupted
`text_only`	Text/tables only, no images
