Orizn MCP Server vs Aviationstack MCP

check_visa_requirement

[needs a free API key — this call will fail without one] THE default visa tool: full entry requirements for ONE passport travelling to ONE destination. Returns visa type (visa_free / visa_required / e_visa / visa_on_arrival / eta / no_admission), days allowed, description, required documents, application steps, visa types, cost, validity, max stay, processing time, country info, plus passport validity months, visa fees, processing days, photo specs, vaccinations, insurance, safety advisory, health requirements, overstay penalties, entry by mode (air/land/sea), transit visa hubs, remote-work visa, extension rules, minor rules, dual-nationality and passport-stamp warnings, and embassies. Answers in any of 15 languages (all plans, including free). Call this whenever the user asks whether they need a visa, what documents or vaccinations are needed, how much a visa costs, how long it takes, how long they can stay, or what happens if they overstay. Requires an API key (free one at https://visa.orizn.app/visa-api). On the free plan some deep fields come back as an {upgrade: ...} placeholder instead of data. Reading the reply: every deep field carries a `granularity` — "destination" means the value describes the destination country for all nationalities (fees, processing days, transit, overstay, safety), "passport" means it describes the passport for all destinations (reciprocity history, stamp and dual-nationality warnings). Only the top-level requirement, visa-free days, description and documents are pair-specific. A field that Orizn does not have comes back as {status: "unavailable"} — say so rather than filling the gap; and `as_of` is the reference date of that field, which is not live data. Get one at https://visa.orizn.app/visa-api?source=mcp (100 requests/month, no card), then set ORIZN_API_KEY in the env block of the MCP config.
