Summary
A stdio proxy that lets Claude Desktop, Cursor, and Continue.dev call six hydration calculators hosted at getvari.app. You get basic daily water intake math, symptom based dehydration checks, trimester aware pregnancy targets, CKD safe fluid restrictions from KDOQI guidelines, ACSM aligned athlete pre/during/post plans with sweat rate estimates, and a time stamped energy optimization schedule. Every response includes a source URL pointing to the methodology page. The package itself is ~50 lines of bridge code; the real computation lives on the Vercel HTTP endpoint. Install via npx in your MCP config, no auth required. Reach for it when you need deterministic, citation ready hydration calculations without writing an HTTP client or hardcoding formulas.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.

@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). |
