从音频中提取主导旋律，并在一个 ZIP 中导出 MIDI、音符事件、音高轮廓、SVG 和 JSON。
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/audio-melody-contour-extractor' \
-H 'Content-Type: application/json' \
-d '{"filename":"audioFile.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/audio-melody-contour-extractor' \
-F 'audioFile=uploads/2026/01/01/your-tool-1700000000000-abc123.ext' \
-F 'onsetThreshold=0.45' \
-F 'frameThreshold=0.28' \
-F 'minNoteLength=4' \
-F 'minNoteMs=80' \
-F 'melodyPreference=balanced' \
-F 'includePitchBends=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-audio-melody-contour-extractor": {

}
}
}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：
