此 MCP 可以做什么

Checks visa and entry requirements for passport holders and destinations, including stay limits, documents, official sources, and multi-leg trip evaluations.

check_entry_requirements
Check entry requirements
Whether a passport holder can enter a destination country: visa-free, visa on arrival, e-visa, eTA, or visa required — with allowed stay, official application portal, extended rules (passport validity, onward ticket, yellow fever, transit-without-visa) and source citations. Free tier: rate limited per caller (see /auth.md to register for a larger quota, or use the x402-paid HTTP API for unlimited access).

evaluate_trip
Evaluate a full trip (paid)
Premium evaluation of a whole trip in one call: multiple passports (best passport per leg), documents held, multi-leg itineraries with transit legs, dates and purpose — with structured why[] explanations, conditions[], and verification states per decision. PAID endpoint: the call returns HTTP 402 x402 payment instructions unless the request carries an x402 payment header; any x402-capable client settles in USDC on Base and retries.
