MCP Fiscal Brasil is a focused Brazilian tax (fiscal) vertical MCP server with broad coverage: from CNPJ/CPF validation and Simples/MEI lookups to NF-e parsing, DANFE generation, XMLDSig signature checks, SPED/eSocial analysis, offline tax tables and 2026 reform (IBS/CBS) simulation, across roughly 44 tools plus a CLI, REST API and Python SDK. Its standout trait is that most functionality needs no account or API key, with much of the processing done locally and offline. Features that need live SEFAZ interaction require your own A1 certificate, which is opt-in and never leaves your machine. It suits Brazilian accounting, ERP and finance-automation teams; it is not for non-Brazilian tax scenarios and should not be treated as an official government project. Be mindful of third-party data source stability and the advisory nature of its tax outputs.

Base URL for BrasilAPI for custom environments, defaults to https://brasilapi.com.br/api; optional.
HTTP_TIMEOUT
HTTP timeout in seconds, defaults to 30; optional.
NFE_CERTIFICADO_PATH
Absolute path to a local .pfx/.p12 A1 certificate, only needed for mTLS tools; optional.
NFE_EMITENTE_CNPJ
14-digit CNPJ of the certificate holder; optional.

Shown for Claude Desktop. Other clients may use a different file or key (VS Code uses "servers") — the configurator below converts it.
{
"servers": {
"fiscal-brasil": {
"command": "uvx",
"args": [
"mcp-fiscal-brasil"
]
}
}
}
Goes in your project's .vscode/mcp.json (VS Code uses a "servers" key).
claude mcp add fiscal-brasil -- uvx mcp-fiscal-brasil
Run it in a terminal; replace any <…> placeholders with your own values first.
After restarting the client, the fiscal-brasil tools (e.g. consultar_cnpj, validate_nfe_full) should appear in the tool list; asking "Consulte o CNPJ 00.000.000/0001-91" and getting real company data (e.g. Banco do Brasil S.A.) confirms the connection.
Once connected, you can ask your AI assistant things like:

MCP Fiscal Brasil is a Brazilian tax (fiscal) vertical MCP server (Python, MIT license, run via uvx from the PyPI package mcp-fiscal-brasil, stdio transport, roughly 44 tools). It exposes CNPJ, CPF, Simples Nacional/MEI, NF-e, NFS-e, SPED, eSocial and tax-certificate lookups as composable tools for MCP clients such as Claude Desktop, Claude Code, Cursor and VS Code + Continue. Most tools work with no API key: CNPJ and Simples Nacional data come from BrasilAPI, while NF-e parsing, DANFE generation, XMLDSig signature validation, SPED/eSocial analysis and offline reference tables (NCM/CFOP/CST/CEST) run locally. A few tools (consultar_status_sefaz, baixar_nfe_distribuicao, manifestar_nfe) optionally require a local A1 digital certificate (.pfx/.p12) for SEFAZ mTLS traffic. Some tools only return government portal URLs or carry explicit limitations (for example, search CNPJ by name). Note: the server is maintained by DeHor-Labs and is not an official MCP or government project.
