MCP 集成

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。

服务配置

将以下内容加入你的 MCP 客户端配置：

mcp.json

{
  "mcpServers": {
    "elysiatools-audio-podcast-trailer-builder": {
      "name": "audio-podcast-trailer-builder",
      "description": "从片头音乐、最多 5 个精彩片段、片段下音乐底噪和响度目标组装出短预告片。",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=audio-podcast-trailer-builder",
      "command": "",
      "args": [],
      "env": {},
      "isActive": true,
      "type": "sse"
    }
  }
}

列出可用工具

连接到 SSE 端点后，列出已开放的工具：

tools/list

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/list"
}

调用此工具

通过工具 id 调用，参数由其参数表构建：

tools/call

{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "tools/call",
  "params": {
    "name": "audio-podcast-trailer-builder",
    "arguments": {
  "introMusic": "https://example.com/file.ext",
  "clip1": "https://example.com/file.ext",
  "clip2": "https://example.com/file.ext",
  "clip3": "https://example.com/file.ext",
  "clip4": "https://example.com/file.ext",
  "clip5": "https://example.com/file.ext",
  "clipDuration": 8,
  "crossfade": 0.3,
  "musicUnderClips": -18,
  "targetLufs": -16,
  "outputFormat": "mp3"
}
  }
}

可用逗号分隔的 toolId 在一个会话中串联多个工具，例如 /mcp/sse?toolId=png-to-webp,jpg-to-webp,gif-to-webp（最多 20 个）。

文件参数仅支持公开的文件链接 URL（https://…）。不支持本地路径、data: URI 和 Base64 字符串。
