About
6 hydration calculators for LLMs: water intake, dehydration, pregnancy, CKD, athlete, energy.
Security Report
6.2
Moderate6.2Moderate RiskThis is a well-designed stdio bridge to a public HTTP-based MCP server. The code is minimal, clean, and handles its single responsibility (proxying MCP requests to an HTTP endpoint) securely. No authentication is required for the upstream service (per design — the tools are public calculators), and the proxy itself has no sensitive operations. The codebase demonstrates good error handling and appropriate logging practices. Supply chain analysis found 2 known vulnerabilities in dependencies (0 critical, 2 high severity). Package verification found 1 issue.

How to Install
Add this to your MCP configuration file:

}
}

@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 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"]
}
}
]
}
}
Configuration
| Env var | Default | Purpose |
|---|---|---|
VARI_MCP_URL | https://getvari.app/api/mcp/v1 | Override the upstream HTTP endpoint (e.g. for staging). |
