Utilities
通过文件的魔数字节签名识别真实类型，而非扩展名。直接读取上传文件，覆盖约 70 种类型。
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/file-type-detect' \
-H 'Content-Type: application/json' \
-d '{"filename":"file.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/file-type-detect' \
-F 'file=uploads/2026/01/01/your-tool-1700000000000-abc123.ext' \
-F 'showHex=true'以 JSON 形式 POST 提交输入参数。文件类型参数需先单独上传。
POST https://api.elysiatools.com/zh/api/tools/file-type-detect| 参数名 | 类型 | 必填 | 说明 |
|---|---|---|---|
| file | file需先上传 | 是 | The file to identify. Only the first 512 bytes are read — large files are safe to upload. |
| showHex | checkbox | 否 | Display the raw hex dump so you can verify the signature manually. |

}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-file-type-detect": {
"name": "file-type-detect",
"description": "通过文件的魔数字节签名识别真实类型，而非扩展名。直接读取上传文件，覆盖约 70 种类型。",
"baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=file-type-detect",
"command": "",
"args": [],
"env": {},
"isActive": true,
"type": "sse"
}
}
}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": "file-type-detect",
"arguments": {
"file": "https://example.com/file.ext",
"showHex": true
}
}
