README

PRJ-03 — Servidor de Resources MCP

Servidor MCP (FastMCP, stdio) que demonstra Resources — a forma padronizada do MCP expor dados (em vez de tools) para o modelo. Corresponde ao Capítulo 4 do livro Model Context Protocol (Sandeco).

Resources expostos

URI Tipo Conteúdo
echo://static estático Identidade do agente (nome via AGENT_NAME, default Giulia-ai).
file://readme arquivo Bytes reais deste README.md.
file://contatos arquivo CSV de contatos (dados de demonstração).
contato://{nome} template dinâmico Busca UM contato pelo nome dentro do CSV.
greeting://{nome} template dinâmico Saudação personalizada.

Correções em relação ao exemplo do livro: caminhos de arquivo agora são resolvidos via pathlib relativos à raiz do projeto (antes eram relativos ao diretório de execução e quebravam), e o CSV correto em data/contatos.csv.

Uso

uv sync
cp .env.example .env        # opcional: definir AGENT_NAME
uv run python src/resources_server.py   # ou: uv run python src/main.py

Os dados de contato são fictícios (demo). Para um cenário real, aponte CONTATOS_PATH para um export do seu CRM ou troque o resource por uma consulta a banco/API.

Testes

uv run pytest        # 20 testes

Cobrem os três formatos de resource e, principalmente, que os caminhos resolvem a partir da raiz do projeto — rodar de outra pasta não pode quebrar.
