Train tickets (12306)

Two hands, in this order. Searching is done with the 12306__* tools, a community MCP server (12306-mcp) that reads 12306's public timetable and seat counts; no login, no browser, no phone, nothing typed into an app. Booking has no API a personal agent may use; it happens on the phone's screen with phone_task, and only when the user has picked a train and said to book it.

Is the server there?

Look for 12306__get-tickets in your tools (the tools list is the only place it can be: no shell command or script to check). If it is not there, say so in one line, give the user the lines to add to config.toml, and, when a phone is connected, offer the search on the phone's screen instead (the old way, below); otherwise stop:

[[mcp.servers]]
name = "12306"
command = "npx"
args = ["-y", "12306-mcp"]
risk = "safe"
egress = true

Node is needed for npx; the phone's own runtime has it.

What you need

• From, to, the date, and whether it must be 高铁/动车 (G/D) or any train. The user's habits from recall (preferred stations, morning or evening, seat class, who travels) count as answers. Ask for the rest with one ask_user call.
• Passengers, seat class and budget only matter for booking; do not ask for them to run a search.
