Content

Public, no-auth MCP server exposing six deterministic hydration calculators backed by getvari.app.

Tools

calculate_water_intake — Personalized daily water target from weight, activity,
climate, caffeine.
dehydration_check — Score severity (well-hydrated / mild / moderate / severe) from
pregnancy_water_intake — Pregnancy / postpartum daily intake (IOM 2004, ACOG).
kidney_safe_intake — CKD fluid-restriction allowance (KDOQI / KDIGO); medical disclaimer included.
athlete_hydration_plan — Pre / during / post hydration plan with sweat-rate estimate
(ACSM, NATA, IOC).
optimize_hydration_for_energy — Time-stamped daily hydration schedule built around
wake/sleep, caffeine timing, and the circadian dip.

Why this is different

Source-attributed — every response includes the underlying study URL.
Deterministic — byte-equal output for byte-equal input. LLM caches behave correctly.
Stateless, no auth, no PII. Rate-limited 600 req/h/IP.
Already in the official MCP Registry as io.github.getvari/vari-mcp@1.0.1.

Zhipu Web SearchZhipu Web Search MCP Server is a search engine specifically designed for large models. It integrates four search engines, allowing users to flexibly compare and switch between them. Building upon the web crawling and ranking capabilities of traditional search engines, it enhances intent recognition capabilities, returning results more suitable for large model processing (such as webpage titles, URLs, summaries, site names, site icons, etc.). This helps AI applications achieve "dynamic knowledge acquisition" and "precise scenario adaptation" capabilities.
