Mcp Nfse Nacional

Overview

Mcp Nfse Nacional is an MCP server that brings NFSe queries from Brazil's national portal (nfse.gov.br) into your AI assistant. With this server connected, Claude, Cursor, VS Code, and other MCP clients can look up Service Tax Notes directly as part of their workflows, eliminating manual lookups and copy-paste steps.

The server runs locally on your machine via the npm package mcp-nfse-nacional, installed with npx -y mcp-nfse-nacional. You'll need to provide your digital certificate details through two environment variables: CERT_FILE and CERT_PASSWORD. Authentication uses an API Key. The latest release is v1.0.3, maintained by SamuelMoraesF and open source on GitHub.

Mcp Nfse Nacional is listed in the Development category on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, claim this listing to verify ownership and keep the information current.
