What is Mcp Demo Golang

MCP Demo Golang is a demonstration project built in Go (Golang) that showcases various functionalities and integrations around tool interactions and protocols. It allows users to query IP location, perform calculations, and generate responses using language models (LLMs). The project serves as a practical example of how to implement and use different transport methods in Go applications.

Use cases

MCP Demo Golang has multiple use cases including IP location querying, basic arithmetic calculations, and enhanced responses through LLMs. It can be utilized by developers interested in learning how to work with microservice architectures, server-client communication, and HTTP or SSE protocols, or those wanting to integrate language models into their applications for more advanced functionality.

How to use

To use MCP Demo Golang, navigate to the project directory and compile the desired tool using the provided Go build commands. Then, run the corresponding client applications to interact with the server. Different tools are available including stdio, http, and sse methods, allowing users to see real-time responses or query processing based on their preferences.

Key features

Key features of MCP Demo Golang include support for multiple transport methods (stdio, http, sse), the ability to implement and demonstrate various protocols, and built-in functionality for querying IP locations and performing calculations. It also offers LLM integration for enhanced user interaction. The structure of the project supports easy extensibility and modification.

Where to use

MCP Demo Golang can be used in educational settings to teach developers the fundamentals of building and interacting with services in Go. It is also applicable in real-world applications for building microservices, enhancing web applications with geographic data, or embedding LLM capabilities into software solutions that require decision-making or interactive responses.
