📦 方式一:MCP Server

MCP 工具

search_google_scholar

搜索 Google Scholar 上的学术文章。

参数:

| 参数 | 类型 | 必填 | 说明 | |------|------|------|------| | query | string | ✅ | 搜索关键词(论文标题、主题或关键词) | | author | string | ❌ | 作者名称筛选 | | year_low | int | ❌ | 起始年份 | | year_high | int | ❌ | 结束年份 | | num_results | int | ❌ | 返回结果数量(默认: 5) |

返回结果:

{
  "bib": {

    "author": "作者",
    "pub_year": "发表年份",
    "venue": "发表期刊/会议",
    "abstract": "摘要"
  },
  "pub_url": "论文链接",
  "num_citations": "被引用次数",
  "citedby_url": "引用链接",
  "eprint_url": "PDF 链接"
}

使用示例

关键词搜索:

result = await mcp.use_tool("search_google_scholar", {
    "query": "deep learning",
    "num_results": 5
})

带作者筛选:

result = await mcp.use_tool("search_google_scholar", {
    "query": "convolutional neural networks",
    "author": "Yann LeCun",
    "num_results": 3
})

带年份范围:

    "query": "transformer",
    "year_low": 2020,
    "year_high": 2024,
    "num_results": 5
})

组合搜索:

result = await mcp.use_tool("search_google_scholar", {

results = search_google_scholar(
    "attention is all you need",
    author="Vaswani",
    year_low=2017,
    year_high=2018,
    num_results=2
)
print(results)

安装

从 PyPI 安装

uv tool install google_scholar_mcp

从 GitHub 安装

uv tool install git+https://github.com/arrogant-R/google_scholar_mcp.git

本地安装 + 开发模式

git clone https://github.com/arrogant-R/google_scholar_mcp.git
cd Google-Scholar-MCP-Server

# 使用 uv(推荐)
uv venv
source .venv/bin/activate  # Windows: .venv\Scripts\activate
uv pip install -e .

# 或使用 pip
pip install -r requirements.txt

google-scholar-mcp

⚙️ 配置 MCP 客户端

使用 uv(从 uv tool 安装后)

{
  "mcpServers": {
    "google-scholar": {
      "command": "uv",
      "args": ["tool", "run", "google_scholar_mcp"]
    }
  }
}

本地开发模式(uv)

{
  "mcpServers": {
    "google-scholar": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/Google-Scholar-MCP-Server",
        "run",
        "google_scholar_mcp"
      ]
    }
  }
}

使用本地 Python

{
  "mcpServers": {
    "google-scholar": {
      "command": "/path/to/python",
      "args": ["-m", "google_scholar_mcp"]
    }
  }
}

VS Code (GitHub Copilot)

{
  "servers": {
    "google_scholar": {
      "type": "stdio",
      "command": "uv",
      "args": ["tool", "run", "google_scholar_mcp"]
    }
  }
}

Claude Desktop

{
  "mcpServers": {
    "google-scholar": {
      "command": "uv",
      "args": ["tool", "run", "google_scholar_mcp"]
    }
  }
}

Windows:

{
  "mcpServers": {
    "google-scholar": {
      "command": "C:\\Users\\YOUR\\PATH\\python.exe",
      "args": ["-m", "google_scholar_mcp"]
    }
  }
}

Cursor

在 Settings → Cursor Settings → MCP → Add new server 中添加:

{
  "google-scholar": {
    "command": "uv",
    "args": ["tool", "run", "google-scholar-mcp"]
  }
}

Cline

{
  "mcpServers": {
    "google-scholar": {
      "command": "uv",

🧩 方式二:OpenClaw Skill

Skill 版本将搜索功能封装为 OpenClaw 技能包,Agent 可直接通过命令行脚本调用搜索能力,无需启动 MCP 服务器进程。

安装

方式一:对话安装

直接对 Agent 说:

「从 GitHub 仓库 arrogant-R/google_scholar_mcp 安装 google-scholar-search 技能」

Agent 会自动从仓库的 skill/google-scholar-search/ 目录下载并安装。

方式二:手动安装

Step 1:安装 CLI 工具

Skill 依赖 google-scholar 命令,需要先安装:

# Via uv (recommended — fast, no proxy issues)
uv tool install google_scholar_mcp

⚠️ Avoid pip install — pip is slow and may fail behind proxies. Use uv instead.

Step 2:复制 Skill 文件

将本仓库 skill/google-scholar-search 目录复制到 ~/.qclaw/skills/

# Windows
Copy-Item -Recurse "./skill/google-scholar-search" "$env:USERPROFILE\.qclaw\skills\google-scholar-search"

# macOS/Linux
cp -r ./skill/google-scholar-search ~/.qclaw/skills/

使用方法

Skill 安装后,Agent 会在用户提及学术论文搜索、Google Scholar、文献检索等场景时自动触发。

Skill 内部调用 google-scholar CLI 命令(由 google_scholar_mcp 包提供),用法如下:

搜索论文

# 基本搜索
google-scholar search "deep learning" --num-results 5

# 带作者筛选
google-scholar search "convolutional neural networks" --author "Yann LeCun"

# 带年份范围
google-scholar search "transformer" --year-low 2020 --year-high 2024

# 组合搜索
google-scholar search "neural networks" --author "Geoffrey Hinton" --year-low 2015 --year-high 2023 --num-results 10

获取 BibTeX 引用

google-scholar bibtex "attention is all you need"

快速搜索(不填充详细信息)

google-scholar search "large language model" --no-fill --num-results 10

CLI 参数

search 命令

| 参数 | 类型 | 默认值 | 说明 | |------|------|--------|------| | query | str | 必填 | 搜索关键词(论文标题、主题或关键词) | | --author | str | None | 作者名称筛选 | | --year-low | int | None | 起始年份 | | --year-high | int | None | 结束年份 | | --num-results | int | 5 | 返回结果数量 | | --no-fill | flag | off | 跳过详细信息填充(更快但数据较少) |

bibtex 命令

| 参数 | 类型 | 默认值 | 说明 | |------|------|--------|------| | query | str | 必填 | 搜索查询(论文标题) | | --num-results | int | 1 | 返回条目数量 |

安装 CLI 工具

google-scholar 命令由 google_scholar_mcp 包提供,安装方式:

# Via uv (recommended)
uv tool install google_scholar_mcp

# Via pip
pip install google_scholar_mcp

安装后即可在任意目录直接使用 google-scholar 命令。

🛡️ 优化特性

CAPTCHA 验证码处理

本项目对 scholarly 库进行了优化,解决了遇到 Google Scholar 验证码时程序卡住的问题:

  1. 自动检测验证码:当检测到验证码时,自动弹出浏览器窗口
  2. 手动验证:在弹出的浏览器中手动完成验证
  3. Cookie 同步:验证完成后后续请求使用自动同步的 Cookie,避免频繁触发验证
  4. Cookie 持久化:将 Cookie 保存到本地文件,下次启动时自动加载,减少验证码出现频率

⚠️ 如果遇到验证码,请在弹出的浏览器窗口中手动完成验证,程序会自动等待并继续执行。

📄 完整摘要获取

当 query 比较完整且精确时,系统会自动获取论文的完整 abstract,而不仅仅是截断的摘要片段。这对于需要详细了解单篇论文内容的场景非常有用。
