Ferramentas fiscais brasileiras: CNPJ, NF-e, IBS/CBS, ICMS, Simples Nacional, NCM/CFOP. Sem API key.
Connect MCP Fiscal Brasil to Claude, Cursor or any other MCP client and it stops being a tab you switch to. Ferramentas fiscais brasileiras: CNPJ, NF-e, IBS/CBS, ICMS, Simples Nacional, NCM/CFOP. Sem API key. The mcp fiscal brasil mcp server is what makes that connection.
O único servidor MCP com suporte nativo a NF-e, NFS-e, SPED, eSocial, Simples Nacional e Reforma Tributária 2026 (IBS/CBS) - sem conta, sem chave e sem configuração.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
Ferramenta — Quando usaranalyze_cnpj_compliance — Relatório consolidado de compliance fiscal de um CNPJrisk_score_supplier — Aprovar, investigar ou recusar fornecedorconsultar_empresas_lote — Triar carteira de fornecedores com score e erro por CNPJcompare_tax_regimes — Comparar regimes tributários por cenáriovalidate_nfe_full — Validar uma NFe completa a partir do XMLsummarize_sped — Transformar SPED em resumo executivoInstallation goes through your MCP client rather than a global install: point it at mcp-fiscal-brasil on PyPI and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Configuration is passed through the environment: NFE_CERTIFICADO_PATH, BRASILAPI_BASE_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. MCP Fiscal Brasil's toolset — Ferramenta, analyze_cnpj_compliance, risk_score_supplier and 4 more — is a fair guide to whether it matches your workflow. It is maintained by DeHor-Labs; worth a glance at recent repository activity before you build anything load-bearing on it.
