百度图片搜索 MCP Server
基于百度图片搜索 API 的 MCP (Model Context Protocol) 服务器。支持图片搜索、下载和格式转换一体化。
功能特性
🔍 图片搜索:搜索百度图片,返回图片标题、URL、尺寸、格式等信息
📥 一键下载:搜索同时可直接下载图片到本地
🔄 格式转换:支持 JPEG、PNG、WebP 三种格式互转(基于 sharp)
🖼️ 双源选择:可选择缩略图(thumburl,百度 CDN 稳定快速)或原图(objurl,可能有防盗链)
📄 分页支持:支持自定义每页数量和页码

技术实现细节
搜索 API
使用百度图片搜索的 acjson 接口:
GET https://image.baidu.com/search/acjson
?tn=resultjson_com
&word={关键字}
&pn={偏移量}
&rn={每页数量}
&gsm={pn的十六进制}
&newReq=1已验证:无需 Cookie 即可调用,直接请求即可返回完整结果
分页通过
pn(偏移量,步长为rn)和gsm(pn的十六进制值)控制响应中包含
totalNum(总结果数)和hasMore(是否有更多)
图片格式检测
下载图片时自动检测格式,优先级:
响应头
Content-Type文件魔数(Magic Bytes)
如果设置了 format 参数且与实际格式不一致,自动使用 sharp 转换。
反爬策略
随机 User-Agent(从多个真实浏览器 UA 中随机选择)
正确的 Referer 头
请求间添加 300-700ms 随机延迟
并发下载数限制为 3
