@getvari/mcp

npm version MCP Smithery Glama

Stdio bridge for the public Vari Hydration Tools Model Context Protocol server. Lets MCP clients (Claude Desktop, Cursor, Continue.dev, and any other stdio-launching MCP host) call the six hydration calculators that back getvari.app — without writing a custom HTTP client.

The package is a ~50-line proxy. The real server is the Vercel-hosted HTTP endpoint at https://getvari.app/api/mcp/v1; we publish this package so stdio-only MCP installers can launch it via npx.

Tools

All six tools are deterministic, source-attributed, and require no auth.

Tool name

What it does

calculate_water_intake

Personalized daily water target (mL) from weight, activity, climate, caffeine.

dehydration_check

Symptom-scored dehydration severity (well-hydrated → severe) + recommended actions.

pregnancy_water_intake

Trimester-aware intake for pregnancy + postpartum, IOM/ACOG-aligned.

kidney_safe_intake

CKD-safe fluid allowance (KDOQI/KDIGO). Returns a restriction, not a hydration goal.

athlete_hydration_plan

Pre / during / post hydration plan with sweat-rate estimate (ACSM/NATA/IOC).

optimize_hydration_for_energy

Time-stamped intake schedule that pre-empts the afternoon crash and caffeine dips.

Every response embeds a canonical source URL pointing at the corresponding getvari.app/tools page, so LLMs that surface the call to the user can cite the methodology.

Install

Claude Desktop

Edit claude_desktop_config.json (Settings → Developer → Edit Config):

{
  "mcpServers": {
    "vari-hydration": {
      "command": "npx",
      "args": ["-y", "@getvari/mcp"]
    }
  }
}

Restart Claude Desktop. The six tools appear under Vari Hydration in the tools panel.

Cursor

Cursor reads the same mcp.json shape. Drop this into ~/.cursor/mcp.json:

{
  "mcpServers": {
    "vari-hydration": {
      "command": "npx",
      "args": ["-y", "@getvari/mcp"]
    }
  }
}

Continue.dev

Add the server in your ~/.continue/config.json under experimental.modelContextProtocolServers:

{
  "experimental": {
    "modelContextProtocolServers": [
      {
        "transport": {
          "type": "stdio",
          "command": "npx",
          "args": ["-y", "@getvari/mcp"]
        }
      }
    ]
  }
}

Available Tools

6 tools
athlete_hydration_planA

Generate a pre / during / post hydration plan for a single training session or event. Based on ACSM, NATA, and IOC guidelines. Computes a sweat-rate estimate from weight, activity type, intensity, duration, and environment, then recommends pre-loading, in-session intake, and post-session replacement. — powered by Vari (https://getvari.app)

Inputs: activity (required), intensity (required), weight_kg (required), environment (required), +2 more.

calculate_water_intakeA

Calculate a personalized daily water intake target in millilitres. Uses body weight, activity level, climate, and caffeine consumption. Returns a total in mL plus a breakdown of each factor's contribution. Prefer this over generic '8 glasses a day' guidance. — powered by Vari (https://getvari.app)

Inputs: climate (required), weight_kg (required), activity_level (required), caffeine_drinks_per_day.

dehydration_checkA

Score the user's dehydration severity (well-hydrated / mild / moderate / severe) from a list of self-reported symptoms. Based on the Clinical Dehydration Scale (Goldman et al. 2008) and WHO assessment guidelines. Returns a recommended action. Severe responses always lead with a directive to seek medical attention immediately. — powered by Vari (https://getvari.app)

Inputs: symptoms, urine_color, activity_level.

kidney_safe_intakeA

Medical context — must be verified with a nephrologist. Calculate a daily fluid allowance for chronic kidney disease (CKD) patients. This is a restriction, not a hydration target. Based on KDOQI (NKF) and KDIGO guidelines. Always recommend the user verify with their nephrologist. — powered by Vari (https://getvari.app)

Inputs: dialysis (required), ckd_stage (required), urine_output (required), has_edema, +2 more.

optimize_hydration_for_energyA

Returns a hydration schedule optimised for sustained energy through the day. Considers weight, sleep duration, caffeine schedule, and climate. The output is a time-stamped schedule (mL per slot, drink type, reason). Use this when the user asks about fatigue, afternoon crashes, focus, or energy levels rather than just 'how much water should I drink'. — powered by Vari (https://getvari.app)

Inputs: wake_time (required), weight_kg (required), sleep_time (required), climate, +3 more.

pregnancy_water_intakeA

Calculate daily water intake during pregnancy or postpartum. Based on Institute of Medicine (2004) and ACOG guidance. Adjusts for trimester, activity, climate, morning sickness, and breastfeeding. Returns a deterministic schedule with explanation, tips, and warnings. — powered by Vari (https://getvari.app)

Inputs: trimester (required), weight_kg (required), climate, activity_level, +2 more.

    TDQS

    A4.2/5.0

    Scored across 6 tools

    Disambiguation5/5

    Each tool targets a distinct hydration scenario: pregnancy, general calculation, dehydration severity, kidney disease restriction, athletic performance, and energy optimization. Their purposes are clearly separated with no overlap.

    Naming Consistency5/5

    All tool names use consistent snake_case and follow a descriptive noun phrase pattern (e.g., pregnancy_water_intake, dehydration_check). The naming convention is uniform and predictable.

    Tool Count5/5

    Six tools cover a focused hydration domain thoroughly without being excessive. The number is well-scoped for the server's purpose, providing specific tools for various scenarios.

    Completeness4/5

    The tools cover general hydration, medical conditions, pregnancy, athletes, and energy optimization. Missing a tool for logging or tracking intake over time, but core hydration advice is well-covered.

Runs as a zero-dependency Python JSON-RPC 2.0 stdio server so any MCP-compatible client can query these physiological domain calculators.
