Common questions

Is MCP Nfe Io safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

You need to fill in: NFEIO_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.2) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Claude Desktop

Add to ~/.config/claude/claude_desktop_config.json:

"mcpServers": { "nfe-io": { "command": "npx", "args": ["-y", "@codespar/mcp-nfe-io"], "env": { "NFEIO_API_KEY": "your-api-key", "NFEIO_COMPANY_ID": "your-company-id-or-cnpj" } } } }

Hosts

NFe.io segments its API across three hostnames. This server maps tools to the correct one automatically:

api.nfse.io — product invoices
api.nfe.io — service invoices + company management
nfe.api.nfe.io — lookups (CNPJ, CEP)

Demo mode

Pass --demo or set MCP_DEMO=true to return canned responses without hitting the network. Useful for documentation, screencasts, and CI.

Enterprise

Need governance, budget limits, and audit trails for agent payments? CodeSpar Enterprise adds policy engine, payment routing, and compliance templates on top of these MCP servers.

Authentication

Set these environment variables before launching the server:

NFEIO_API_KEY *(required, secret)* — API key for NFe.io (issuance + query)
NFEIO_COMPANY_ID — Default company ID (CNPJ or NFe.io company UUID) to use when not provided per-call

Issue credentials at the provider's developer portal: https://nfe.io/docs.
