bncc-mcp
Description
Servidor MCP da BNCC (Base Nacional Comum Curricular), o currículo oficial da educação básica brasileira. Dá a agentes de IA acesso às 1.721 aprendizagens da BNCC e do complemento de Computação, extraídas dos documentos homologados pelo MEC e verificadas contra a fonte. Cada habilidade e objetivo de aprendizagem traz o código, o texto oficial e a proveniência (a página do PDF de onde veio), o que permite ao agente citar a origem em vez de alucinar códigos: a numeração da BNCC tem lacunas legítimas, e o servidor responde explicando isso quando um código não existe. Sete tools: bncc_lookup (busca por código), bncc_buscar (busca textual), bncc_listar, bncc_estatisticas, bncc_decodificar (explica a anatomia de um código como EF67LP08), bncc_progressao_ei e bncc_estrutura. Casos de uso: planejamento de aulas alinhado ao currículo, geração de atividades e avaliações com habilidades corretas, análise de material didático, ferramentas para professores e edtechs brasileiras.

Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Tool names are action-oriented and indicate purpose (e.g., 'lookup', 'buscar', 'listar').
- Some tools explicitly mention error handling (e.g., bncc_decodificar handles non-existent codes).
Weaknesses
- Descriptions contain incomplete sentences (e.g., bncc_buscar ends with 'U', bncc_listar cuts off 'Computação').
- Parameter requirements are unclear (e.g., bncc_listar filters lack explicit 'required/optional' labels).
- Tool overlap exists (e.g., bncc_lookup vs. bncc_buscar both handle BNCC searches).
bncc_buscar— Description ends abruptly with 'U' (likely a typo or incomplete text).bncc_listar— Description cuts off 'Computação' without explanation.bncc_progressao_ei— Limited scope (only EI codes) not clearly emphasized in description.
