No authentication required.\n\n## 🔌 Client configuration\n\nAdd this to your MCP client's `mcpServers` configuration (Claude Desktop `claude_desktop_config.json`, Cursor `mcp.json`, Cline, Cherry Studio, etc.):\n\n```json\n{\n  \"mcpServers\": {\n    \"weather\": {\n      \"type\": \"http\",\n      \"url\": \"https://mcp.pianam.cn/weather-mcp/mcp\"\n    }\n  }\n}\n```\n\n> Clients that do not accept `\"type\": \"http\"` (some Cherry Studio / older\n> Cline versions) accept the same entry with just `\"url\"`.\n\n## 🧰 Tools\n\n| Tool | Parameters | Returns |\n|---|---|---|\n| `query_weather(city, days=3)` | `city`: Chinese or English city name, e.g. `\"青岛\"`, `\"北京\"`, `\"Tokyo\"`.<br>`days`: forecast days, 1–7 (default 3). | Current conditions (weather text, temperature, feels-like, humidity, wind direction/speed) + daily forecast (date, weather, high/low, precipitation probability). |\n\n## 📡 Data sources, caching & limits\n\n- Primary source: **[Open-Meteo](https://open-meteo.com/)** — free, **no API key, no registration**; geocoding + forecast, with Chinese-language city resolution (administrative-city ranking to avoid village name collisions).\n- Automatic fallback: **[wttr.in](https://wttr.in/)** if the primary source fails.\n- WMO weather codes and wind directions are translated to Chinese in the output.\n- Results cached for **600 seconds**; the hosted endpoint is rate-limited to **200 requests / minute / IP**.\n\n## 🐢 Self-hosting\n\n```bash\ngit clone https://github.com/boy-373/weather-mcp-china.git\ncd weather-mcp-china\npip install -r requirements.txt\npython weather_mcp_server.py\n# the server listens on 127.0.0.1:8004 by default; override with:\n#   MCP_HOST=0.0.0.0 MCP_PORT=9000 python weather_mcp_server.py\n#   MCP_ALLOWED_HOSTS=\"your-domain.com,127.0.0.1:*\"\n#   MCP_ALLOWED_ORIGINS=\"https://your-domain.com\"\n```\n\nThen point your MCP client at `http://127.0.0.1:8004/mcp`.\nNo API keys or accounts are ever required.\n\n\n\n## 🗂️ Files\n\n- `weather_mcp_server.py` — the MCP server (FastMCP, Streamable HTTP transport).\n- `rate_limit.py` — lightweight per-IP sliding-window rate-limit middleware (200 req/min default).\n- `requirements.txt` — `mcp`, `uvicorn`, `starlette`.\n- `server.json` — official MCP Registry manifest (remote server entry, ready to publish with `mcp-publisher`).\n- `smithery.yaml` / `glama.json` — directory listing metadata.\n\n---\n\n## 🇨🇳 中文使用说明\n\n**一句话**：全球城市实时天气与多日预报，中文城市名直接查、结果中文输出，最长 7 天预报。\n\n**在线直连地址（免费、无需 Key、开箱即用）**：`https://mcp.pianam.cn/weather-mcp/mcp`\n\n在 MCP 客户端（Claude Desktop / Cursor / Cherry Studio / Cline 等）的配置里加入：\n\n```json\n{\n  \"mcpServers\": {\n    \"weather\": {\n      \"type\": \"http\",\n      \"url\": \"https://mcp.pianam.cn/weather-mcp/mcp\"\n    }\n  }\n}\n```\n\n**工具**：\n\n- `query_weather(city, days)`：查天气。城市名中英文均可（「青岛」「北京」「Tokyo」），`days` 为预报天数（1-7，默认 3）。\n- 返回当前天气（天气状况/温度/体感温度/湿度/风向风速）+ 每日预报（日期/天气/最高最低温/降水概率）。\n- 主数据源 Open-Meteo（免费无需 Key），故障自动切换 wttr.in。\n\n**服务特性**：数据源全部为公开接口、无需注册/付费；服务端内存缓存、失败自动降级/切换备用通道；单 IP 限流 200 次/分钟。\n\n**本地部署**：\n\n```bash\ngit clone https://github.com/boy-373/weather-mcp-china.git\ncd weather-mcp-china\npip install -r requirements.txt\npython weather_mcp_server.py\n# 默认监听 127.0.0.1:8004，可用环境变量 MCP_HOST / MCP_PORT / MCP_ALLOWED_HOSTS / MCP_ALLOWED_ORIGINS 覆盖\n```\n\n## 📄 License\n\n[MIT](LICENSE) © 2026 boy-373\n\n## Install via Smithery\n\nOne-click install for [Smithery](https://smithery.ai)-supported clients (Claude Desktop, Cursor, etc.):\n\n[![Smithery](https://smithery.ai/badge/1561852680/weather-mcp-china)](https://smithery.ai/servers/1561852680/weather-mcp-china)\n\nOr run:\n\n```bash\nnpx -y @smithery/cli install 1561852680/weather-mcp-china --client claude\n```\n\n---\n\n## 🔌 Use with Any AI Client — One-Click MCP Gateway\n\nWe host a free **MCP aggregation gateway**: your AI assistant (Cherry Studio, Claude Desktop, Cursor, Cline — any MCP client) discovers and uses MCP tools through a single URL:\n\n```\nhttps://mcp.pianam.cn/ai/mcp\n```\n\nAdd it once, then talk in plain language — the AI automatically **searches → inspects → calls** the right MCP for you.\n\n- 🔍 Search across **22,000+** indexed MCP servers (Chinese & English)\n- ⚡ **50+ live hosted MCPs** callable directly out of the box (weather, exchange rates, hot trends, IP geo, train tickets…)\n- 📦 GitHub-based MCPs: search finds them with links to install locally\n- ✅ Servers health-checked weekly — alive ones ranked first\n- 🆓 Free to use, no key required\n\n**📖 3-step setup guide / 中文接入教程**: https://mcp.pianam.cn/ai-gateway\n",
