All limitations / Review context

Has mcp-server-12306 changed its specific MCP integration, install method or privilege scope, and does it justify shortlist promotion?

High-impact permissions explicitly documented; no known blocker to an accurately caveated public Radar listing in limited first-party review.

Unofficial interface; upstream anti-automation and availability may change; no account-booking claim without verification.
Scoped by connected account, local OS, and configuration; verify exact permissions before installation.
Network connectivity to 12306 data sources

Complete write authority is not verified.
Installation, client compatibility and comprehensive security have not been independently audited. Authentication and access depend on the configured services.
No exhaustive advisory or runtime review performed; never infer installation safety.
Write actions/tool inventory not confirmed against exact tool documentation; listed action classes remain illustrative or context-dependent. Empty inventory does not establish read-only.
Setup and runtime permissions are implementation- and account-specific; follow linked upstream documentation.

Warning

Train data service may be region-specific; do not assume supported geography.
This command may start a stdio MCP server rather than registering it; show the publisher client config alongside it, not as a standalone complete integration step.
Use this JSON only with Claude Desktop. Replace credential and path placeholders with your own settings.
Exact vendor-specific credential revoke procedure not established from checked official Setup documentation; may be external or not applicable. Do not invent.
publisher README config shape Replace the supplied credential/path placeholders privately; use only the named configuration schema.
MCP100 client-scope note: this Claude Code CLI example applies only to that client and the exact registered name in the command. Desktop, Cursor and other clients use their own configuration; do not run it for a differently named entry.

Suggested check
Inspect 12306 available tools and query static station data before live ticket enquiries.
Remove / uninstall / revoke
MCP100 setup guide
Remove `12306` entry from MCP client config. Using uvx requires no global package uninstall.
MCP100 client-scope guidance: each CLI removal example targets only its named client and exact registered entry. Package names, Desktop/Cursor configuration keys and Codex/Claude registration names may differ; use the entry you actually registered. Client removal does not revoke provider credentials.

Which tasks are documented for this implementation?

The reviewed tasks include: Find available train routes; Check ticket inventory and station metadata; Compare connecting rail itineraries; Query mainland China 12306 train availability and routing.

What setup and authentication are documented?

A complete connection procedure is not verified. Client notes: Command provided only where first-party command or package existence is established; verify the client configuration against upstream documentation. Installation/authentication detail is incomplete; do not infer settings from package name. These facts do not supply missing installation commands, credentials or a verified authentication procedure. Authentication: Network connectivity to 12306 data sources

Can it modify data or perform write operations?

Not verified. The available evidence does not establish the complete write authority. Recorded permission context: Scoped by connected account, local OS, and configuration; verify exact permissions before installation.

What data-handling boundary should I consider?

Train data and user searches

What limitations and risks should I check before use?

Unofficial interface; upstream anti-automation and availability may change; no account-booking claim without verification. Setup and runtime permissions are implementation- and account-specific; follow linked upstream documentation. Repository pushed_at explicitly observed. No exhaustive advisory or runtime review performed; never infer installation safety.
