cnki-mcp
Enables AI assistants to search CNKI (China National Knowledge Infrastructure), download PDFs, and import them into Zotero with automatic PDF attachment.
README
cnki-mcp
把中国知网(CNKI)的**文献检索 → PDF 下载 → 导入 Zotero(自动迁移并关联 PDF)**封装成 MCP 工具,供 Claude 等 AI 助手一键调用。
An MCP server that lets an AI assistant search CNKI (China National Knowledge Infrastructure), download article PDFs, and import them into Zotero with the PDF automatically attached.
✨ 功能
- 检索 CNKI 学术期刊/学位论文(表单交互,绕开失效的 URL 参数检索)
- 下载 单篇或批量 PDF/CAJ 到本地
- 导入 Zotero:优先本地 connector(
localhost:23119),把 PDF 直接上传并关联为子附件;Zotero 未运行时降级云 API(仅元数据) - 登录态持久化:Cookie 保存/恢复,几小时内免重复登录
- 一键批量:
cnki_batch串起 检索→下载→导入→清理暂存
🧰 MCP 工具
| 工具 | 说明 |
|---|---|
cnki_login_status |
检查机构登录状态 |
cnki_open_login_page |
打开登录页,等待手动完成机构登录并保存 Cookie |
cnki_save_cookies |
手动保存当前 Cookie |
cnki_search |
按关键词检索期刊论文 |
cnki_download_pdf |
下载单篇 PDF/CAJ |
cnki_import_to_zotero |
把元数据列表导入 Zotero(可带 pdf_path 自动关联 PDF) |
cnki_batch |
一键:检索 → 下载 → 导入 Zotero |
📦 环境要求
- Python 3.10+(MCP SDK 要求)
- Playwright + 系统 Chrome(或内置 Chromium)
- 有效的 CNKI 机构访问权限(校园网/VPN/机构账号)
- 可选:Zotero 7+ 桌面端(用于 PDF 自动关联)
🚀 安装
方式 A:pip 安装(推荐,提供 cnki-mcp 命令)
# 从 GitHub 直接安装(或 pip install cnki-mcp 若已上 PyPI)
pip install git+https://github.com/wuruiqi/cnki-mcp.git
python -m playwright install chromium # 若无系统 Chrome
安装后即有 cnki-mcp 控制台命令,启动 stdio MCP 服务器。
方式 B:克隆源码
git clone https://github.com/wuruiqi/cnki-mcp.git
cd cnki-mcp
pip install -r requirements.txt
python -m playwright install chromium
cp .env.example .env # 按需修改配置
注册到 MCP 客户端
pip 安装后(用 cnki-mcp 命令,最简洁):
{
"mcpServers": {
"cnki": { "type": "stdio", "command": "cnki-mcp" }
}
}
uvx 免安装运行:
{
"mcpServers": {
"cnki": {
"type": "stdio",
"command": "uvx",
"args": ["--from", "git+https://github.com/wuruiqi/cnki-mcp.git", "cnki-mcp"]
}
}
}
克隆源码方式(直接指向 server.py):
{
"mcpServers": {
"cnki": {
"type": "stdio",
"command": "python",
"args": ["/abs/path/to/cnki-mcp/server.py"]
}
}
}
⚙️ 配置(.env)
所有项均可选,路径默认相对项目根目录。详见 .env.example。
| 变量 | 默认 | 说明 |
|---|---|---|
ZOTERO_LOCAL_API |
http://127.0.0.1:23119 |
Zotero 本地 connector 地址 |
ZOTERO_API_KEY / ZOTERO_LIB_ID |
— | 仅离线降级到云 API 时需要 |
PDF_DIR |
./downloads |
PDF 暂存目录 |
PROFILE_DIR |
./.browser_profile |
浏览器持久化目录 |
COOKIE_FILE |
./.cnki_cookies.json |
Cookie 存储文件 |
DELETE_PDF_AFTER_IMPORT |
true |
成功关联 Zotero 后删除暂存 PDF |
📖 使用流程
cnki_login_status查登录态;未登录则cnki_open_login_page,在弹出的浏览器里完成机构登录(机构登录 → 校外登录 → 学校 → 账号密码 → 接受条款),脚本自动存 Cookie。cnki_search "粮情监测 物联网"检索。cnki_batch "粮情监测 物联网"一键检索+下载+导入 Zotero。
⚠️ 说明与限制
- PDF 自动关联需 Zotero 桌面端在运行(走本地 connector);未运行则降级为仅写元数据。
- 若系统配置了 HTTP 代理,访问 Zotero 本地端口需绕过代理 —— 本项目已用
httpx(trust_env=False)处理。 - 仅供个人学习研究用途,请遵守 CNKI 服务条款与所在机构的使用规定。
🛠 开发
诊断脚本见 tests/(inspect_* / probe_*):CNKI 改版导致选择器失配时,运行它们 dump 实时 DOM 重新定位。实测要点记录在 CLAUDE.md。
