Compression
上传 PNG/APNG，解析动画结构：PNG 签名与逐块 CRC32 校验、IHDR（位深/颜色类型/隔行）、acTL（帧数与播放次数，必须位于首个 IDAT 之前）、fcTL（序号、区域约束 x+y+w+h ≤ 画布、delay_num/delay_den 归一化、dispose_op none/background/previous、blend_op source/over）、IDAT 首帧 + fdAT 后续帧；共享的 fcTL+fdAT 序号必须从 0 连续递增；逐帧回放 deflate 流并核对解压尺寸 = 高 × (1 + 每行字节数)，报告 zlib 损坏；dispose 语义模拟提示首帧 previous 视作 background、零延迟帧等。
用三种语言从你的代码中调用此工具。
# 1) Request a presigned URL → returns { uploadUrl, storageKey }
curl -X POST 'https://api.elysiatools.com/api/upload/presign/apng-idat-fdat-chunk-streaming-deflate-replay-and-disposal-method-analyzer' \
-H 'Content-Type: application/json' \
-d '{"filename":"pngFile.ext","contentType":"application/octet-stream","size":12345}'
# 2) PUT the file bytes directly to the presigned uploadUrl
curl -X PUT '<presigned uploadUrl>' \
--data-binary @/path/to/file.ext
# 3) Call the tool, passing the returned storageKey for each file field
curl -X POST 'https://api.elysiatools.com/zh/api/tools/apng-idat-fdat-chunk-streaming-deflate-replay-and-disposal-method-analyzer' \
-F 'pngFile=uploads/2026/01/01/your-tool-1700000000000-abc123.ext' \
-F 'verifyDeflate=true'以 JSON 形式 POST 提交输入参数。文件类型参数需先单独上传。

}将此工具加入你的 Model Context Protocol 服务，让 AI 智能体可以列出并调用它。
将以下内容加入你的 MCP 客户端配置：
