What exercises are available?

The database includes 1000+ exercises covering cardio, strength training, stretching, plyometrics, powerlifting, Olympic weightlifting and strongman. Each exercise includes step-by-step instructions and equipment needed.

03

How can I calculate my daily calorie needs?

Use the calculate_bmr tool to find your Basal Metabolic Rate, then multiply it by your activity level to get your TDEE (Total Daily Energy Expenditure). This tells you exactly how many calories you need to maintain your current weight.

04

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.

05

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.

06

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.
