有个mcp服务是这样的：

bash
展开代码
    "newsnow": {
      "command": "npx",
      "args": [
        "-y",
        "newsnow-mcp-server"
      ],
      "env": {
        "BASE_URL": "http://101.126.150.28:9044"
      }
    }

方法 1: 使用 Python MCP 客户端（推荐）

python
展开代码
import asyncio
import json
from mcp import ClientSession, StdioServerParameters
from mcp.client.stdio import stdio_client

async def list_mcp_tools():
    # 配置服务器参数
    server_params = StdioServerParameters(
        command="npx",
        args=["-y", "newsnow-mcp-server"],
        env={"BASE_URL": "http://101.126.150.28:9044"}
    )
    
    async with stdio_client(server_params) as (read, write):
        async with ClientSession(read, write) as session:
            # 初始化连接
            await session.initialize()
            
            # 获取工具列表
            tools = await session.list_tools()
            
            print("可用的工具：")
            print(json.dumps(tools.model_dump(), indent=2, ensure_ascii=False))

# 运行
asyncio.run(list_mcp_tools())

安装依赖：

bash
展开代码
uv pip install mcp

得到描述：

bash
展开代码
{
  "meta": null,
  "nextCursor": null,
  "tools": [
    {
      "name": "get_hottest_latest_news",
      "title": null,
      "description": "get hottest or latest news from source by {id}, return {count: 10} news.",

          },
          "count": {
            "default": 10,
            "description": "count of news to return."
          }
        },
        "required": [
          "id"
        ],
        "additionalProperties": false,
        "$schema": "http://json-schema.org/draft-07/schema#"

      "outputSchema": null,
      "icons": null,
      "annotations": null,
      "meta": null
    }
  ]
}

方法 2: 使用 MCP Inspector（可视化工具）

bash
展开代码
# 安装 MCP Inspector
npm install -g @modelcontextprotocol/inspector

# 运行 Inspector 连接你的 MCP 服务器
npx @modelcontextprotocol/inspector
