Why AutoGen?
AutoGen enables multi-agent conversations where agents negotiate, delegate, and collaboratively use API Ninjas tools. Connect 8 tools through Vinkius and assign role-based access. a data analyst queries while a reviewer validates, with optional human-in-the-loop approval for sensitive operations.

Frequently asked questions
How do I get an API Ninjas key?
Sign up for free at api-ninjas.com/register. Free tier includes 10,000 requests/month.
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.
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.
How does AutoGen connect to MCP servers?
Create an MCP tool adapter and assign it to one or more agents in the group chat. AutoGen agents can then call API Ninjas tools during their conversation turns.
Can different agents have different MCP tool access?
Yes. AutoGen's role-based architecture lets you assign specific MCP tools to specific agents, so a querying agent has different capabilities than a reviewing agent.
Does AutoGen support human approval for tool calls?
Yes. Configure human-in-the-loop mode so agents pause and request approval before executing sensitive MCP tool calls.
