bash

# 1. 初始化 session，获取 session ID
SESSION_ID=$(curl -s -D - -X POST http://192.168.71.7:8000/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -H "Authorization: Bearer $XINIUDATA_MCP_TOKEN" \
  -d '{
    "jsonrpc": "2.0",
    "method": "initialize",
    "params": {
      "protocolVersion": "2024-11-05",
      "capabilities": {},
      "clientInfo": {"name": "mcp-calculator", "version": "1.0.0"}
    },
    "id": 1
  }' | grep -i "mcp-session-id" | awk '{print $2}' | tr -d '\r')

# 2. 发送 initialized 通知
curl -s -X POST http://192.168.71.7:8000/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -H "Authorization: Bearer $XINIUDATA_MCP_TOKEN" \
  -H "mcp-session-id: $SESSION_ID" \
  -d '{"jsonrpc":"2.0","method":"notifications/initialized"}'

# 3. 调用 add 工具
curl -s -X POST http://192.168.71.7:8000/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -H "Authorization: Bearer $XINIUDATA_MCP_TOKEN" \
  -H "mcp-session-id: $SESSION_ID" \
  -d '{
    "jsonrpc": "2.0",
    "method": "tools/call",
    "params": {"name": "add", "arguments": {"a": 123, "b": 456}},
    "id": 2
  }'

# 或者调用 subtract 工具
curl -s -X POST http://192.168.71.7:8000/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -H "Authorization: Bearer $XINIUDATA_MCP_TOKEN" \
  -H "mcp-session-id: $SESSION_ID" \
  -d '{

    "method": "tools/call",
    "params": {"name": "subtract", "arguments": {"a": 100, "b": 30}},
    "id": 3
  }'
