使用方法

与 Claude Desktop 集成

添加到你的 ~/.config/claude/claude_desktop_config.json (Linux/Windows) 或 ~/Library/Application Support/Claude/claude_desktop_config.json (macOS):

开发/未发布版本配置

{
  "mcpServers": {
    "pdf-tools-mcp": {
      "command": "uv",
      "args": [
        "--directory",
        "<path/to/the/repo>/pdf-tools-mcp",
        "run",
        "pdf-tools-mcp",
        "--workspace_path",
        "</your/workspace/directory>"
      ]
    }
  }
}

已发布版本配置

{
  "mcpServers": {
    "pdf-tools-mcp": {
      "command": "uvx",
      "args": [
        "pdf-tools-mcp",
        "--workspace_path",
        "</your/workspace/directory>"
      ]
    }
  }
}

注意: 出于安全考虑，此工具只能访问指定工作目录(--workspace_path)内的文件，无法访问工作目录之外的文件。

如果配置后无法正常工作或在UI中无法显示，请通过 uv cache clean 清除缓存。

作为命令行工具

# 基本使用
pdf-tools-mcp

# 指定工作目录
pdf-tools-mcp --workspace_path /path/to/workspace

作为 Python 包

from pdf_tools_mcp import read_pdf_pages, get_pdf_info, merge_pdfs, extract_pdf_pages

# 读取 PDF 页面
result = await read_pdf_pages("document.pdf", 1, 5)

# 获取 PDF 信息
info = await get_pdf_info("document.pdf")

# 合并 PDF 文件
result = await merge_pdfs(["file1.pdf", "file2.pdf"], "merged.pdf")

# 提取特定页面
result = await extract_pdf_pages("source.pdf", [1, 3, 5], "extracted.pdf")

主要工具函数

1. read_pdf_pages

读取 PDF 文件指定页面范围的内容

参数:

• pdf_file_path (str): PDF 文件路径
• start_page (int, 默认 1): 起始页码
• end_page (int, 默认 1): 结束页码

示例:

# 读取第 1-5 页
result = await read_pdf_pages("document.pdf", 1, 5)

# 读取第 10 页
result = await read_pdf_pages("document.pdf", 10, 10)

2. get_pdf_info

获取 PDF 文件的基本信息

参数:

• pdf_file_path (str): PDF 文件路径

返回信息:

• 总页数
• 标题
• 作者
• 创建者
• 创建日期

3. merge_pdfs

合并多个 PDF 文件

参数:

• pdf_paths (List[str]): 要合并的 PDF 文件路径列表
• output_path (str): 合并后的输出文件路径

4. extract_pdf_pages

从 PDF 中提取特定页面

参数:

• source_path (str): 源 PDF 文件路径
• page_numbers (List[int]): 要提取的页码列表（从 1 开始）
• output_path (str): 输出文件路径

错误处理

工具自动处理以下情况：

• 负数页码：自动调整为第 1 页
• 超出 PDF 总页数的页码：自动调整为最后一页
• 起始页大于结束页：自动交换
• 文件未找到：返回相应错误信息
• 权限不足：返回相应错误信息

使用示例

# 获取 PDF 信息
info = await get_pdf_info("sample.pdf")
print(info)

# 读取前 3 页
content = await read_pdf_pages("sample.pdf", 1, 3)
print(content)

# 读取最后一页（假设 PDF 有 10 页）
content = await read_pdf_pages("sample.pdf", 10, 10)
print(content)

# 合并多个 PDF
result = await merge_pdfs(["part1.pdf", "part2.pdf", "part3.pdf"], "complete.pdf")
print(result)

# 提取特定页面
result = await extract_pdf_pages("source.pdf", [1, 3, 5, 7], "selected.pdf")
print(result)

注意事项

• 页面范围使用包含区间，即起始页和结束页都包含在内
• 如果指定页面没有文本内容，将被跳过
• 返回结果会显示 PDF 总页数和实际提取的页面范围
• 支持各种语言的 PDF 文档
• 建议一次读取的页面数不超过 50 页，以避免性能问题

Usage

Usage with Claude Desktop

Add to your ~/.config/claude/claude_desktop_config.json (Linux/Windows) or ~/Library/Application Support/Claude/claude_desktop_config.json (macOS):

Development/Unpublished Servers Configuration

{
  "mcpServers": {
    "pdf-tools-mcp": {
      "command": "uv",
      "args": [
        "--directory",
        "<path/to/the/repo>/pdf-tools-mcp",
        "run",
        "pdf-tools-mcp",
        "--workspace_path",
        "</your/workspace/directory>"
      ]
    }
  }
}

Published Servers Configuration

{
  "mcpServers": {
    "pdf-tools-mcp": {
      "command": "uvx",
      "args": [
        "pdf-tools-mcp",
        "--workspace_path",
        "</your/workspace/directory>"
      ]
    }
  }
}

Note: For security reasons, this tool can only access files within the specified workspace directory (--workspace_path) and cannot access files outside the workspace directory.

In case it's not working or showing in the UI, clear your cache via uv cache clean.

As a command line tool

# Basic usage
pdf-tools-mcp

# Specify workspace directory
pdf-tools-mcp --workspace_path /path/to/workspace

As a Python package

from pdf_tools_mcp import read_pdf_pages, get_pdf_info, merge_pdfs, extract_pdf_pages

# Read PDF pages
result = await read_pdf_pages("document.pdf", 1, 5)

# Get PDF info
info = await get_pdf_info("document.pdf")

# Merge PDF files
result = await merge_pdfs(["file1.pdf", "file2.pdf"], "merged.pdf")

# Extract specific pages
result = await extract_pdf_pages("source.pdf", [1, 3, 5], "extracted.pdf")

Main Tool Functions

1. read_pdf_pages

Read content from specified page ranges of a PDF file

Parameters:

• pdf_file_path (str): PDF file path
• start_page (int, default 1): Starting page number
• end_page (int, default 1): Ending page number

Example:

# Read pages 1-5
result = await read_pdf_pages("document.pdf", 1, 5)

# Read page 10
result = await read_pdf_pages("document.pdf", 10, 10)

2. get_pdf_info

Get basic information about a PDF file

Parameters:

• pdf_file_path (str): PDF file path

Returns:

• Total page count
• Title
• Author
• Creator
• Creation date

3. merge_pdfs

Merge multiple PDF files

Parameters:

• pdf_paths (List[str]): List of PDF file paths to merge
• output_path (str): Output file path for the merged PDF

4. extract_pdf_pages

Extract specific pages from a PDF

Parameters:

• source_path (str): Source PDF file path
• page_numbers (List[int]): List of page numbers to extract (1-based)
• output_path (str): Output file path

Error Handling

The tool automatically handles the following situations:

• Negative page numbers: automatically adjusted to page 1
• Page numbers exceeding total PDF pages: automatically adjusted to the last page
• Start page greater than end page: automatically swapped
• File not found: returns appropriate error message
• Insufficient permissions: returns appropriate error message

Usage Examples

# Get PDF info
info = await get_pdf_info("sample.pdf")
print(info)

# Read first 3 pages
content = await read_pdf_pages("sample.pdf", 1, 3)
print(content)

# Read last page (assuming PDF has 10 pages)
content = await read_pdf_pages("sample.pdf", 10, 10)
print(content)

# Merge multiple PDFs
result = await merge_pdfs(["part1.pdf", "part2.pdf", "part3.pdf"], "complete.pdf")
print(result)

# Extract specific pages
result = await extract_pdf_pages("source.pdf", [1, 3, 5, 7], "selected.pdf")
print(result)

Notes

• Page ranges use inclusive intervals, meaning both start and end pages are included
• Pages without text content will be skipped
• Results show total PDF page count and actual extracted page range
• Supports PDF documents in various languages
• Recommended to read no more than 50 pages at a time to avoid performance issues
