把文字藏进 PNG 的最低有效位、再原样提取，并运行 Westfeld–Pfitzmann 卡方隐写分析（含滑窗 p 曲线与 LSB 位平面预览）。
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 'http://127.0.0.1:3003/api/upload/presign/image-steganography-embed-detect' \
-H 'Content-Type: application/json' \
-d '{"filename":"imageFile.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 'http://127.0.0.1:3003/zh/api/tools/image-steganography-embed-detect' \
-F 'imageFile=uploads/2026/01/01/your-tool-1700000000000-abc123.ext' \
-F 'mode=embed' \
-F 'secretText=Meet at the old harbor at 9pm — bring the blue key.' \
-F 'scatterSeed=harbor-2026' \
-F 'channels=rgb' \
-F 'skipTransparent=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：
{
"mcpServers": {
"elysiatools-image-steganography-embed-detect": {
"name": "image-steganography-embed-detect",
"description": "把文字藏进 PNG 的最低有效位、再原样提取，并运行 Westfeld–Pfitzmann 卡方隐写分析（含滑窗 p 曲线与 LSB 位平面预览）。",

}
}
}连接到 SSE 端点后，列出已开放的工具：
{
"jsonrpc": "2.0",
"id": 1,
"method": "tools/list"
}通过工具 id 调用，参数由其参数表构建：
{
"jsonrpc": "2.0",
"id": 2,
"method": "tools/call",
"params": {
"name": "image-steganography-embed-detect",
"arguments": {
