China 12306 Train Tickets MCP

Query China Railway 12306 ticket availability from any MCP client — train schedules and remaining seats by Chinese station name and date. Read-only, no booking, no account.

• Try it in 30 seconds: a free public MCP endpoint is already running — just paste the URL into your MCP client (no install, no API key).
• Or self-host: a single Python file, stdlib HTTP + FastMCP, zero paid dependencies.

⚡ Use the hosted endpoint (no setup)

https://mcp.pianam.cn/train-mcp/mcp

Transport: Streamable HTTP (MCP 2025-03-26 compatible). No authentication required.

🔌 Client configuration

Add this to your MCP client's mcpServers configuration (Claude Desktop claude_desktop_config.json, Cursor mcp.json, Cline, Cherry Studio, etc.):

{
  "mcpServers": {
    "12306-train": {
      "type": "http",
      "url": "https://mcp.pianam.cn/train-mcp/mcp"
    }
  }
}

Clients that do not accept "type": "http" (some Cherry Studio / older Cline versions) accept the same entry with just "url".

🧰 Tools

📡 Data sources, caching & limits

• Data comes from 12306's own public query endpoints (kyfw.12306.cn/otn/leftTicket/...) — read-only queries only; this server cannot book tickets, please buy via the official 12306 app/website.
• Station code table cached locally for 7 days; ticket queries cached for 300 seconds.
• No API key, no login required.
• The hosted endpoint is rate-limited to 60 requests / minute / IP.

🐢 Self-hosting

git clone https://github.com/boy-373/12306-train-mcp.git
cd 12306-train-mcp
pip install -r requirements.txt
python train_mcp_server.py
# the server listens on 127.0.0.1:8003 by default; override with:
#   MCP_HOST=0.0.0.0 MCP_PORT=9000 python train_mcp_server.py
#   MCP_ALLOWED_HOSTS="your-domain.com,127.0.0.1:*"
#   MCP_ALLOWED_ORIGINS="https://your-domain.com"

Then point your MCP client at http://127.0.0.1:8003/mcp. No API keys or accounts are ever required.

• train_stations.json — bundled 12306 station name → telegraph-code table (auto-refreshed from 12306 every 7 days).

🗂️ Files

• train_mcp_server.py — the MCP server (FastMCP, Streamable HTTP transport).
• rate_limit.py — lightweight per-IP sliding-window rate-limit middleware (60 req/min default).
• requirements.txt — mcp, uvicorn, starlette.
• server.json — official MCP Registry manifest (remote server entry, ready to publish with mcp-publisher).
• smithery.yaml / glama.json — directory listing metadata.

🇨🇳 中文使用说明

一句话：直接用中文站名查 12306 余票，数据来自 12306 官方公开查询接口，纯只读。

在线直连地址（免费、无需 Key、开箱即用）：https://mcp.pianam.cn/train-mcp/mcp

在 MCP 客户端（Claude Desktop / Cursor / Cherry Studio / Cline 等）的配置里加入：

{
  "mcpServers": {
    "12306-train": {
      "type": "http",
      "url": "https://mcp.pianam.cn/train-mcp/mcp"
    }
  }
}

工具：

• query_train_tickets(from_city, to_city, date)：查余票。出发/到达站直接给中文城市或车站名（如「青岛」「北京南」），日期格式 YYYY-MM-DD，留空默认明天；返回车次、出发到达时间、历时及商务座/一等座/二等座/软卧/硬卧/硬座/无座等余票。
• search_station(keyword)：不确定城市有哪些车站时模糊搜索站名（如「北京」返回 北京/北京南/北京西/北京北 等）。
• 仅查票，不能购票；12306 预售期通常 15 天。

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 60 次/分钟。

本地部署：

git clone https://github.com/boy-373/12306-train-mcp.git
cd 12306-train-mcp
pip install -r requirements.txt
python train_mcp_server.py
# 默认监听 127.0.0.1:8003，可用环境变量 MCP_HOST / MCP_PORT / MCP_ALLOWED_HOSTS / MCP_ALLOWED_ORIGINS 覆盖
