What it can do

Tool names and descriptions exactly as the server reported them on Nov 10, 2026. The maker wrote them, not us; we show them as plain text.

  • check_china_twov_nationality_eligibility

    Verify whether a passport nationality qualifies for China 240-hour (upgraded from 72/144-hour) Visa-Free Transit (TWOV) and 24-hour direct airside transit.

  • validate_third_country_itinerary_rule

    Validate whether a flight routing (Origin Country/Region A -> Mainland China B -> Destination Country/Region C, including Hong Kong, Macau, or Taiwan) satisfies strict NIA TWOV third-region rules vs round-trip disqualification.

  • calculate_transit_stay_deadline

    Calculate the exact legal departure deadline under China Immigration midnight-next-day counting rules (00:00 the day following arrival) for 240-hour / 144-hour transit stays.

  • lookup_china_transit_port_zone

    Look up permitted stay regions and approved entry/exit airports, seaports, and rail ports for Beijing-Tianjin-Hebei, Shanghai-Jiangsu-Zhejiang, Guangdong, Chengdu, Chongqing, Xi’an, and 24 provinces.

  • check_24hour_direct_transit_rules

    Check rules for the 24-hour visa-free transit policy available to almost all nationalities, including multi-stop domestic transfers within 24 hours and airport-specific exemptions.

  • get_airline_checkin_boarding_checklist

    Generate the mandatory printed document checklist required at airline check-in desks and China Immigration Temporary Entry Permit counters to prevent erroneous denied boarding.

  • lookup_china_visa_photo_specs

    Retrieve official Chinese Embassy COVA digital visa photo and physical print dimensions (33mm x 48mm, head height 28-33mm, pure white RGB 255,255,255 background).

  • compare_twov_vs_unilateral_30day_visa_free

    Compare whether a traveler can use China’s 30-day unilateral visa-free entry (allows round-trip flights) vs 240-hour TWOV (requires third-country onward ticket).

Common questions

Is CheckChinaTransit — China 24/240-Hour Visa-Free Transit Compliance Engine safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry today.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?
