An MCP server that provides 12306 ticket query

Overview

AI-generated overview

A local MCP server that lets an assistant query China Railway 12306 train tickets, prices, stations, transfers and stop schedules.

What you can do
Query remaining tickets, train numbers, seat classes and departure times for a route and date, with optional filtering by train number and real-time fares per seat class for each train, plus official transfer itineraries with full paths and waiting times, and all stop stations and arrival/departure times for a given train, and look up the official unique number for a train code, and search the national station list by Chinese name, pinyin, initials or three-letter code, and get the current time in any time zone and relative date calculations to help pick a travel date.
When to use it
Useful when an assistant should help plan rail travel in China: checking availability and fares for a route and date, comparing direct trains with transfer options, or looking up station names and stop schedules.
Requirements
Runs locally as a Python package (Python 3.10 to below 3.14) via uvx, pip or pipx, or as a Docker image; network access to the official 12306 interfaces is required. An optional HTTP mode listens on port 8000 and is configured with SERVER_HOST, SERVER_PORT, DEBUG and LOG_LEVEL. No accounts or API keys are declared.
Before you install
The README states the project is for learning and research only, forbids commercial use, and that users bear all consequences, including possible account bans or legal risk. It forwards requests to official 12306 interfaces and does not store or alter official data. The HTTP mode defaults to listening on 0.0.0.0, so bind it to a local address if exposed.

Installation

In SourceWeft

  1. Open Mcp Server 12306 in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

🚀 快速开始

环境要求

依赖要求
Python>= 3.10, < 3.14
包管理器uv(推荐)或 pip / pipx
网络可访问 12306 官方接口

💡 推荐使用 uv:环境隔离、安装快、锁文件管理依赖版本。

方式一:Stdio 模式(本地客户端推荐)

MCP Server 通过标准输入/输出与客户端通信,不占用网络端口,适合 Claude Desktop、Cursor 等本地 MCP 客户端。

安装:

bash
# uvx(推荐,环境隔离)uvx mcp-server-12306
# 或 pip / pipxpip install mcp-server-12306

客户端配置(如 claude_desktop_config.json):

json
{  "mcpServers": {    "12306": {      "command": "uvx",      "args": ["mcp-server-12306"]    }  }}
其他安装方式(点击展开)

pipx:

json
{  "mcpServers": {    "12306": {      "command": "pipx",      "args": ["run", "--no-cache", "mcp-server-12306"]    }  }}

本地源码(开发者调试):

bash
git clone https://github.com/drfccv/mcp-server-12306.gitcd mcp-server-12306uv sync
json
{  "mcpServers": {    "12306": {      "command": "uv",      "args": ["--directory", "/path/to/mcp-server-12306", "run", "mcp-server-12306"]    }  }}

方式二:Streamable HTTP 模式(远程部署)

Server 启动 Web 服务(默认 8000 端口),通过 MCP Streamable HTTP 协议通信:POST 发送 JSON-RPC、GET 订阅流式响应、DELETE 结束会话。

启动:

bash
# 安装后直接启动mcp-12306
# 或本地源码启动uv run python scripts/start_server.py

客户端配置:

json
{  "mcpServers": {    "12306": {      "url": "http://localhost:8000/mcp"    }  }}

内置 HTTP 端点:

端点方法说明
/mcpPOST / GET / DELETEMCP Streamable HTTP 协议入口
/healthGET健康检查(含已加载车站数、活跃会话数)
/schema/toolsGET全部工具 JSON Schema
/GET服务信息(版本、协议版本、端点)

方式三:Docker 部署

bash
# 拉取镜像并运行(默认端口 8000)docker run -d -p 8000:8000 --name mcp-server-12306 drfccv/mcp-server-12306:latest
# 自定义端口docker run -d -p 8080:8000 \  -e SERVER_HOST=0.0.0.0 \  -e SERVER_PORT=8000 \  --name mcp-server-12306 \  drfccv/mcp-server-12306:latest

🧑‍💻 开发指南

bash
# 1. 克隆并初始化git clone https://github.com/drfccv/mcp-server-12306.gitcd mcp-server-12306uv sync
# 2. 类型检查(mypy,严格模式)uv run mypy src scripts
# 3. 代码格式化uv run black src scriptsuv run isort src scripts
# 4. 构建与发布uv run python -m builduv run twine upload dist/*

架构要点:

  • server.py 是传输无关的核心模块——工具注册(TOOL_HANDLERS)与业务分发(call_tool)都在此,stdio 与 HTTP 复用同一实例,保证两种模式行为完全一致。
  • 工具 Schema 单一来源于 ticket_service.MCP_TOOLS,HTTP 的 /schema/tools 端点与 MCP 工具列表同源。
  • 网络请求统一走 _request_with_retry(自动重试 + init 会话保持),业务错误与网络错误分离处理。

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
