mcp-fiscal-brasil

What it does

MCP server that lets an AI assistant query Brazil's fiscal systems: CNPJ lookups, NF-e, NFS-e and CT-e, SPED, eSocial and Simples Nacional, via 44 tools with offline tables. It runs on Python 3.10 or later with no API key by default; SEFAZ web services need an A1 certificate; a paid cpfcnpj.com.br token is optional. The README is in Portuguese; some NFS-e tools only give URLs and instructions.
