This MCP server implements a straightforward echo service via the Model Context Protocol (MCP) using .NET Core technology. It listens for incoming messages and echoes the same message back to the client, with the ability to customize message formats through configuration settings like appsettings.json or environment variables. It's designed to be lightweight and easy to deploy, either directly or via Docker container. The server supports integration with MCP-compatible clients, allowing for seamless testing and development of message-based interactions. Its modular design and configurability make it ideal for scenarios where simple message validation or response confirmation is needed, as well as for demonstrating MCP standards and protocols.
