Mcp Nfe Io

Overview

Mcp Nfe Io is an MCP server that connects AI assistants to NFe.io, enabling access to NF-e, NFS-e, CNPJ, and CEP services. It exposes Brazilian fiscal and business data tools that Claude, Cursor, VS Code, and other AI agents can invoke directly within their workflows.

The server runs locally via the npm package @codespar/mcp-nfe-io and communicates with your AI client over stdio. You'll need to provide your NFe.io API key through the NFEIO_API_KEY environment variable. Version v0.2.2 is available under the MIT license, with source code hosted at codespar/mcp-dev-latam on GitHub, where the project has reached 269 stars.

Mcp Nfe Io belongs in the AI & Agents category and works seamlessly with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. Install it with npx -y @codespar/mcp-nfe-io. If you maintain this server, claim your listing to earn the Verified badge and keep information up to date.
