calc-financeira-br

CI Licença: MIT

🇧🇷 Português · 🇺🇸 English

Servidor MCP open source que dá ao Claude (e a qualquer cliente MCP) cálculos financeiros brasileiros exatos e explicados: renda fixa, comparação de investimentos, taxas equivalentes e financiamentos.

LLMs erram contas com juros compostos, dias úteis e faixas de imposto. Este servidor faz a conta de forma determinística e devolve a memória de cálculo passo a passo; o modelo cuida da conversa.

⚠️ Em desenvolvimento (pré-alfa). Ainda não publicado no PyPI.

Diferenciais

  • Precisão de mercado: CDI na base 252 dias úteis com calendário de feriados (ANBIMA), IOF dia a dia e Decimal em vez de float.

  • Memória de cálculo: cada resultado mostra taxa diária, IOF, base do IR e a alíquota aplicada.

  • Regras versionadas: alíquotas e tabelas ficam em arquivos de configuração, com a fonte oficial citada.

  • Validação pública: testes comparados com calculadoras de referência.

English

Open source MCP server that gives Claude (and any MCP client) exact, explained Brazilian financial calculations: fixed income (CDB, LCI/LCA, Tesouro, savings), investment comparison, equivalent rates and loans (SAC/Price).

Every result includes a step-by-step calculation trail and the assumptions used. Results are simulations, not investment advice.

⚠️ Work in progress (pre-alpha). Not yet published on PyPI. Tool names and descriptions are in Portuguese.
