1. 初始化会话，获取会话 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 $XINIUDATAMCPTOKEN \
-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. 发送初始化通知

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 $XINIUDATAMCPTOKEN \ -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 $XINIUDATAMCPTOKEN \ -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 $XINIUDATAMCPTOKEN \ -H mcp-session-id: $SESSION_ID \ -d { jsonrpc: 2.0, method: tools/call, params: {name: subtract, arguments: {a: 100, b: 30}}, id: 3 }
