What is the Physiological Hydration Metric Engine MCP Server?
Generic AI prompts telling users to 'drink 8 glasses of water' represent outdated and physiologically inaccurate science. True hydration must scale dynamically with human biology. The Physiological Hydration Engine computes exact milliliter targets and maps them onto a strict circadian temporal schedule.
Algorithmic Precision
- Metabolic Baseline Processing: Evaluates the biological baseline (35ml per kg) against strict modifiers for metabolic exertion (from sedentary to elite athlete) and environmental thermal stress (cold vs tropical climates).
- Circadian Fluid Distribution: Calculates the exact waking duration (between the provided wake and sleep timestamps) and automatically segments the total hydration target into 6 strategic ingestion milestones (e.g., 'Morning Flush', 'Pre-Sleep Sip').
- Temporal Rollover Math: LLMs frequently fail when parsing nighttime sleep schedules (e.g., waking at 14:00, sleeping at 06:00). The underlying V8 engine utilizes robust mathematical rollovers to flawlessly navigate nocturnal and shift-worker workflows.
- Zero-Dependency Native Execution: Bypasses external health APIs, ensuring sensitive biological inputs are processed strictly on local infrastructure.
Built-in capabilities (5)
Requires weightKg, and accepts optional physical/climate/time modifiers. Computes optimal physiological hydration targets and synthesizes a complete circadian fluid distribution schedule in one step
Provide totalMl and optionally wakeTimeStr and sleepTimeStr. Distributes a specified total water volume evenly across waking hours into specific physiological milestones
Provide weight in kg. Activity level defaults to sedentary and climate to temperate. Calculates the daily water volume requirement based on body mass, physical exertion, and thermal environment
g. sedentary, athlete). Retrieves the exact biological water penalty (in ml) caused by specific physical exertion levels
g. cold, tropical). Retrieves the exact thermal water penalty (in ml) caused by specific environmental climates

Frequently asked questions
Does this support night-shift workers?
Yes. The temporal rollover math guarantees that if you wake up at 18:00 and go to sleep at 08:00, the schedule perfectly plots the 14-hour window across midnight without chronological errors.
Why break the hydration into segments?
Drinking 2 liters of water at once overburdens the kidneys and triggers rapid diuretic flushing, nullifying cellular hydration. Segregating the intake across 'Morning Flush', 'Mid-Day', and 'Pre-Sleep' checkpoints ensures optimal biological absorption.
Why use this tool instead of asking ChatGPT?
LLMs often struggle to perform 5 simultaneous biological modifier calculations while mapping percentages perfectly across base-60 timestamps. This native MCP eliminates mathematical hallucinations entirely.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
