MCP Fiscal Brasil

Overview

MCP Fiscal Brasil is a Model Context Protocol (MCP) server: Ferramentas fiscais brasileiras: CNPJ, NF-e, IBS/CBS, ICMS, Simples Nacional, NCM/CFOP. Sem API key. Because it speaks the Model Context Protocol, AI assistants can use MCP Fiscal Brasil as a set of callable tools instead of you copy-pasting between apps.

It runs locally: the Python package mcp-fiscal-brasil (via uvx) speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v0.3.1, published under the MIT license, with source at DeHor-Labs/mcp-fiscal-brasil on GitHub, where it has earned 279 stars.

On mcp.site, MCP Fiscal Brasil sits in the Finance category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
