What is MCP Go SDK?
The MCP Go SDK is a Go library that provides a comprehensive implementation of the Model Context Protocol (MCP). It facilitates bidirectional communication between clients and servers, enabling features like tool execution, resource access, and prompt handling using various transport layers.
How to use MCP Go SDK?
To use the MCP Go SDK, first install it using go get github.com/SetiabudiResearch/mcp-go-sdk. Then, create a server instance, add tools, resources, and prompts, and configure a transport layer (stdio, SSE, or WebSocket). Finally, start the transport to enable communication.
