知乎 Scraper MCP Server

一个 MCP Server，为 MCP 客户端提供知乎全文正文、完整评论树、分类型搜索的读取能力。

它是对 zhihu-toolkit CLI（zhihu 命令）的薄封装：每个工具都调用 CLI 的 --json 接口，把结果裁剪成精简结构再返回，避免头像/HTML/冗余时间戳等字段撑爆模型上下文。

它专注三块能力：回答/文章全文、完整评论树、按类型的精确搜索——适合需要精确列表、抓正文、抓评论的场景。

能力概览

工具 作用
search_questions 按关键词搜索问题（标题/描述/回答数/浏览量/关注数/URL）
search_articles 按关键词搜索文章（专栏）
search_users 按关键词搜索用户
search_topics 按关键词搜索话题
get_fulltext 传入 URL，返回回答/文章的完整正文（Markdown）；问题 URL 返回其下全部回答的合并全文
get_comments 返回任意内容下的完整评论树（含嵌套子评论、点赞、作者、时间）

环境要求

  • Python 3.12+
  • uv
  • 一份知乎登录态（Cookie），通过 zhihu auth paste 导入；本 Server 不管理、不存储凭据。

快速开始

见 INSTALL.md（面向 Claude Code / Agent 自安装）。工具的详细参数与使用建议见 USAGE.md。

一句话版本：

git clone https://github.com/luyanhexay/zhihu-scraper-mcp.git
cd zhihu-scraper-mcp
uv sync --locked
.venv/bin/zhihu auth paste     # 粘贴浏览器 DevTools 复制的 cURL，Ctrl+D 结束

然后在 Claude Code 中注册（把 <ABS> 换成本仓库绝对路径）：

claude mcp add zhihu-scraper -- <ABS>/.venv/bin/zhihu-scraper-mcp

凭据与隐私

  • 认证信息由 zhihu CLI 存放在 ~/.zhihu-cli/，不在本仓库内。
  • 本仓库不包含任何 Cookie；.gitignore 额外拦截 cookies.json 等文件以防误提交。
  • 分发本仓库不会泄露你的知乎账号。使用者需自行导入自己的登录态。

已知问题

  • 单篇回答的 HTML 端点常被知乎风控（__zse_ck）拦截。get_fulltext 会自动回退到"从问题 API 中挑出对应回答"的路径，因此请尽量传含 /question/<id>/answer/<id> 的完整回答 URL。
  • 搜索关键词要精简（≤3 词），过长易返回空。
  • 触发风控时先在浏览器完成验证，再重新 zhihu auth paste 刷新登录态。
