Arnfa

MCP server for Arnfa — weather-aware trip planning across Thailand. Lets any AI agent read the Thai sky and plan a weather-fit day in 150+ areas (Bangkok neighbourhoods & districts, all 76 province cities, tourist hotspots).

Reads Arnfa's open API — no key, no fabrication (real forecast or an honest error).

Tools

• arnfa_list_areas(query?, tier?) — find a valid area key (search by Thai/English name).
• arnfa_plan_day(area, budget?, day?) — an ordered, weather-fit itinerary; day 0–6 plans ahead.
• arnfa_sky_now(area) — current sky + a go-out verdict for one area.
• arnfa_where(day?) — rank WHERE the sky is clearest across Thailand ("ไปไหนดี").
• arnfa_cooling_centers(lat, lng, n?) — nearest official Bangkok cooling refuges (ห้องหลบร้อน) for dangerous heat / PM2.5.
• arnfa_ask(message, prior?) — ask in natural Thai/English; the grounded engine reads the real sky and narrates a plan. Pass back the previous reply's intent as prior to refine (multi-turn).
