API 延迟预算规划器

规划并可视化 API 延迟预算。输入 P99 目标（如 ≤ 300ms）和各阶段分配（DNS、TCP、TLS、TTFB、Processing、Network），查看实时瀑布图、预算占用和超标告警。可选粘贴 OpenTelemetry 或 Datadog trace，反推基于真实测量的分配建议。

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-api-latency-budget-planner": {
      "name": "api-latency-budget-planner",
      "description": "规划并可视化 API 延迟预算。输入 P99 目标（如 ≤ 300ms）和各阶段分配（DNS、TCP、TLS、TTFB、Processing、Network），查看实时瀑布图、预算占用和超标告警。可选粘贴 OpenTelemetry 或 Datadog trace，反推基于真实测量的分配建议。",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=api-latency-budget-planner",
      "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": "api-latency-budget-planner",
    "arguments": {
  "budget": 300,
  "allocation": "DNS=5\nTCP=10\nTLS=20\nTTFB=80\nProcessing=120\nNetwork=40",
  "slo": "p99",
  "trace": ""
}
  }
}

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）。
