About 12306 MCP

This is a connector that lets AI assistants search for train tickets on China's 12306 railway booking system. It works with the Model Context Protocol (MCP), a standard way to connect AI to external tools and data sources.

Who it’s for

Developers or organizations in China who want to integrate train ticket search into AI-powered applications. Users who need automated access to Chinese railway information.

Alternatives

  • Fliggy MCP: Alibaba's flight and hotel booking connector (broader travel scope)
  • Custom REST wrapper: Build your own lightweight API proxy around 12306 with fine-grained access control
  • Official 12306 API: Contact the railway authority directly for authorized integration options

Setup

Check these steps against the project’s own instructions before running anything.

Follow the project's README on GitHub for installation steps, which likely involve cloning the repository and configuring it with your Claude Desktop or other MCP-compatible AI tool.

These are public popularity signals, not a maintenance check. Look at the repository’s commit history and open issues.

Risks to watch for

  • Direct access to 12306: The connector can query the real Chinese railway system, potentially retrieving or booking tickets if extended with more features
  • Account credentials: If configured with login credentials, those secrets could be exposed or misused by the AI
  • Personal travel data: Search queries reveal travel dates, routes, and passenger preferences to the connector and any system logging it
  • Injection attacks: Maliciously crafted ticket search requests could trick the connector into harmful behavior or expose backend errors
  • Rate limiting bypass: Repeated automated searches could trigger account lockouts or IP bans on 12306

How to lower the risk

Least-privilege permissions

  • Run the connector in a sandboxed environment with minimal network access
  • Never provide real 12306 account passwords; use read-only tokens if available

Network isolation

  • Restrict outbound connections to only the 12306 API endpoints it needs
  • Use a VPN or proxy if the deployment region differs from China

Monitoring

  • Log all ticket searches and flag unusual query patterns
  • Alert on any failed authentication attempts or rate-limit errors

Red flags to watch for

  • Unexpected searches for multiple passengers or future dates in bulk
  • Requests that occur outside normal business hours
  • Errors mentioning account lockouts or IP restrictions
