12306-mcp

作者 Joooook · Joooook/12306-mcp

Query China's 12306 railway tickets via AI — search trains, check availability, and plan routes with natural language.

12306-mcp is an MCP server that connects AI assistants to China's official 12306 railway system. It supports ticket availability queries, train filtering, transit stop lookups, and multi-leg transfer planning. Runs via npx, Docker, or HTTP mode for flexible deployment.

選擇你的客戶端

~/Library/Application Support/Claude/claude_desktop_config.json  · Windows: %APPDATA%\Claude\claude_desktop_config.json
{
  "mcpServers": {
    "12306-mcp-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/Joooook/12306-mcp"
      ]
    }
  }
}

開啟 Claude Desktop → Settings → Developer → Edit Config。儲存後重啟應用。

~/.cursor/mcp.json · .cursor/mcp.json
{
  "mcpServers": {
    "12306-mcp-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/Joooook/12306-mcp"
      ]
    }
  }
}

Cursor 使用與 Claude Desktop 相同的 mcpServers 格式。專案級設定優先於全域。

VS Code → Cline → MCP Servers → Edit
{
  "mcpServers": {
    "12306-mcp-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/Joooook/12306-mcp"
      ]
    }
  }
}

點擊 Cline 側欄中的 MCP Servers 圖示，然後選 "Edit Configuration"。

~/.codeium/windsurf/mcp_config.json
{
  "mcpServers": {
    "12306-mcp-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/Joooook/12306-mcp"
      ]
    }
  }
}

格式與 Claude Desktop 相同。重啟 Windsurf 生效。

~/.continue/config.json
{
  "mcpServers": [
    {
      "name": "12306-mcp-2",
      "command": "TODO",
      "args": [
        "See README: https://github.com/Joooook/12306-mcp"
      ]
    }
  ]
}

Continue 使用伺服器物件陣列，而非映射。

~/.config/zed/settings.json
{
  "context_servers": {
    "12306-mcp-2": {
      "command": {
        "path": "TODO",
        "args": [
          "See README: https://github.com/Joooook/12306-mcp"
        ]
      }
    }
  }
}

加入 context_servers。Zed 儲存後熱重載。

claude mcp add 12306-mcp-2 -- TODO 'See README: https://github.com/Joooook/12306-mcp'

一行命令搞定。用 claude mcp list 驗證，claude mcp remove 移除。

How to find the cheapest train between two cities with 12306-mcp

👤 Travelers planning trips within China ⏱ ~5 min beginner

何時使用： You need to compare train options between two Chinese cities and find the best deal.

前置條件
  • 12306-mcp server running — npx -y 12306-mcp
步驟
  1. Search for available trains
    Search for trains from Beijing to Shanghai tomorrow. Show me all available options with prices and seat types.✓ 已複製
    → A table of trains with departure times, durations, seat classes, and prices
  2. Filter by preference
    Which of these has second-class seats available and arrives before 6pm?✓ 已複製
    → Filtered list matching the criteria

結果： A clear comparison of train options to make a booking decision.

注意事項
  • Station names must match 12306's database exactly — Use the station search tool first to confirm the correct station name

Plan a multi-leg train journey with transfers using 12306-mcp

👤 Travelers heading to cities without direct trains ⏱ ~10 min beginner

何時使用： No direct train exists between your origin and destination.

前置條件
  • 12306-mcp server running — npx -y 12306-mcp
步驟
  1. Query transfer options
    I need to get from Chengdu to Lhasa by train. Find me transfer routes with the shortest total travel time.✓ 已複製
    → One or more transfer itineraries with intermediate stations and connection times
  2. Check availability on each leg
    Check ticket availability for each leg of the recommended route on March 15.✓ 已複製
    → Seat availability for both legs of the journey

結果： A complete multi-leg itinerary with confirmed availability.

注意事項
  • Tight transfer windows may cause missed connections — Ask Claude to filter for transfers with at least 2 hours between trains

故障排查

常見錯誤與修復

Station name not found

Use the station search tool to find the exact name. Chinese station names must match the 12306 database — try both simplified Chinese and pinyin.

驗證： Search for the station by keyword first
No trains found for the given date

12306 only sells tickets 15 days in advance. Ensure your date is within the booking window.

驗證： Try a date within the next 15 days
Connection timeout

The 12306 API can be slow during peak booking times (e.g., Spring Festival). Retry after a few minutes.

驗證： Test with a simple station search to confirm connectivity

替代方案
