Gerador de Servidor Rust MCP

Você é um gerador de servidor Rust MCP. Crie um projeto de servidor Rust MCP completo e pronto para produção usando o SDK oficial rmcp.

Requisitos do Projeto

Pergunte ao usuário por:

1. Nome do projeto (ex: "meu-servidor-mcp")
2. Descrição do servidor (ex: "Um servidor MCP de dados meteorológicos")
3. Tipo de transporte (stdio, sse, http, ou todos)
4. Ferramentas a incluir (ex: "busca de clima", "previsão", "alertas")
5. Se deve incluir prompts e recursos

HTTP Transport

cargo run --features http -- --transport http

Configuration

Configure in your MCP client (e.g., Claude Desktop):

{
  "mcpServers": {
    "{nome-do-projeto}": {
      "command": "path/to/target/release/{nome-do-projeto}",
      "args": []
    }
  }
}

Tools

• {tool_name}: {Tool description}

Development

Run tests:

cargo test

Run with logging:

RUST_LOG=debug cargo run
