}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-opus-to-mp3": {
"name": "opus-to-mp3",
"description": "将 Opus 音频转换为 MP3，支持比特率、采样率和声道选择",

"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": "opus-to-mp3",
"arguments": {
"audioFile": "https://example.com/file.ext",
"bitrate": "192",
"sampleRate": "auto",
"channels": "auto",
"keepMetadata": true
