Source code Documentation

Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package @getvari/mcp
Claude Code 
claude mcp add vari-mcp -- npx -y @getvari/mcp@1.0.1
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "vari-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "@getvari/mcp@1.0.1"
            ]

@getvari/mcp

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 nameWhat it does
calculate_water_intakePersonalized daily water target (mL) from weight, activity, climate, caffeine.
dehydration_checkSymptom-scored dehydration severity (well-hydrated → severe) + recommended actions.
pregnancy_water_intakeTrimester-aware intake for pregnancy + postpartum, IOM/ACOG-aligned.
kidney_safe_intakeCKD-safe fluid allowance (KDOQI/KDIGO). Returns a restriction, not a hydration goal.
athlete_hydration_planPre / during / post hydration plan with sweat-rate estimate (ACSM/NATA/IOC).
optimize_hydration_for_energyTime-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"]
        }
      }
    ]
  }
}
