📌 **记得修改两处占位符**：
1. `your_api_key_here` → 提醒用户替换（不用真填）
2. `yourusername` → 你的 GitHub 用户名
3. `[Your Name]` → 你的名字

## 四、现在你的项目结构长这样 ✅

weather-mcp-server/ ├── pyproject.toml ├── README.md ├── LICENSE ├── .python-version └── src/ └── weather_mcp/ ├── init.py └── server.py

---

## 五、下一步你可以做什么

1. `uv build` → 构建 wheel
2. `uv publish` → 发布到 PyPI
3. 在 TRAE / Claude Desktop 里用 `uvx weather-mcp-server` 体验“一键运行”

如果你愿意，下一步我可以帮你：
- ✅ 检查 `pyproject.toml` 是否 100% 符合 PyPI 要求
- ✅ 帮你写 `.gitignore`
- ✅ 模拟一次“发布前的最终检查清单”
- ✅ 教你如何给 MCP Server 加版本号和 CHANGELOG

你想继续哪一步？ 😊
