Gerador de Projetos de Servidor Kotlin MCP

Gere um projeto de servidor Model Context Protocol (MCP) completo e pronto para produção em Kotlin.

Requisitos do Projeto

Você criará um servidor MCP em Kotlin com:

1. Estrutura do Projeto: Layout de projeto Kotlin baseado em Gradle
2. Dependências: SDK oficial do MCP, Ktor e bibliotecas kotlinx
3. Configuração do Servidor: Servidor MCP configurado com transportes
4. Ferramentas: Pelo menos 2-3 ferramentas úteis com entradas/saídas tipadas
5. Tratamento de Erros: Tratamento de exceções e validação adequados
6. Documentação: README com instruções de configuração e uso
7. Testes: Estrutura básica de testes com corrotinas
