What is the Metabolic Energy Estimator MCP Server?
Autonomous health and fitness agents demand uncompromising metabolic accuracy. When standard LLMs attempt to estimate calories burned for a specific activity, they guess wildly. The Metabolic Energy Estimator MCP empowers your AI Agent by delegating this logic to a deterministic engine utilizing scientifically validated MET (Metabolic Equivalent of Task) values.
Core Capabilities
- Agentic Calorie Estimation: Search a native, offline catalog of over 80 specific physical activities and calculate exact calories burned based on the user's exact weight and duration.
- TDEE & BMR Engine: Implements the rigorous Mifflin-St Jeor equation to establish the user's Basal Metabolic Rate and Total Daily Energy Expenditure without sending health metrics to the cloud.
- Weight Loss Projection: Compute the exact number of days and weeks required to hit a target weight given a precise daily caloric deficit, complete with safety warnings.
Built-in capabilities (4)
Calculates Total Daily Energy Expenditure (TDEE) and Basal Metabolic Rate (BMR) using the Mifflin-St Jeor equation
1kg of fat = 7700 calories. Projects how many days and weeks it will take to reach a target weight based on a daily calorie deficit
You MUST provide an activityId found via search_activity_catalog. Calculates exactly how many calories are burned doing a specific physical activity based on weight and time
Searches the deterministic local catalog for activities and their exact MET values

Frequently asked questions
How does it calculate the calories burned?
The estimate_calories_burned tool uses the standard metabolic formula: Calories = MET * weight(kg) * time(hours). It pulls the exact MET value from its internal activity catalog.
What formula is used for Basal Metabolic Rate (BMR)?
The calculate_tdee tool uses the Mifflin-St Jeor equation, which is currently considered the most accurate standard for predicting resting metabolic rate.
How does it project weight loss?
The calculate_weight_loss_projection tool uses the biological constant that 1kg of body fat equals approximately 7700 calories. It divides the total required deficit by your daily deficit to predict the exact timeline.
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.
