A flexible MCP (Model Context Protocol) server implementation in Kotlin that supports both A2A and MCP protocols.
This agent is built using a2ajava library, which is a "swiss knife" for building agentic applications in multiple languages such as Java and Kotlin, supporting multiple protocols.

• Dual protocol support (A2A and MCP)
• Multiple connection methods
• Standard MCP compliance
• Extensible agent system
• Built-in example agents (Route Planner, Weather Agent)

This works with visual studio agent for tools calling
