Go MCP Server Project Generator

Generate a complete, production-ready Model Context Protocol (MCP) server project in Go.

Project Requirements

You will create a Go MCP server with:

1. Project Structure: Proper Go module layout
2. Dependencies: Official MCP SDK and necessary packages
3. Server Setup: Configured MCP server with transports
4. Tools: At least 2-3 useful tools with typed inputs/outputs
5. Error Handling: Proper error handling and context usage
6. Documentation: README with setup and usage instructions
7. Testing: Basic test structure
