}
}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": "subtitle-framerate-retime-converter",
"arguments": {
"subtitleText": "1\n00:00:10,000 --> 00:00:12,000\nFirst line\n\n2\n00:01:00,000 --> 00:01:02,000\nLast line",
"retimeMode": "preset",
"fpsPreset": "23.976-to-25",
"sourceFps": 25,
"targetFps": 23.976,
"linearFactor": 1,
"point1NowMs": 0,
"point1TargetMs": 0,
"point2NowMs": 0,
"point2TargetMs": 0,
"outputFormat": "srt"
}
}
}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）。
