What do I need to use this MCP?

You need a valid Focus NFe API Token and your Base URL to connect the MCP to your agent.

Which AI clients can I use?

You can use any MCP-compatible client, including Claude, Cursor, and Windsurf.

Can I download PDF files?

Yes, you can use the capability to download DANFE PDFs for your NF-e documents.

How do I fix a mistake on an invoice?

You can tell your agent to send a CC-e (Correction Letter) for the specific NF-e that has an error.

Is this for NF-e or NFS-e?

The MCP supports both NF-e and NFS-e, including capabilities to list emitted or received documents for both types.

What is a CC-e (Carta de Correção)?

CC-e is a Correction Letter used to fix minor errors in an authorized NF-e, such as typos in the buyer's address or product descriptions. It cannot be used to change values, quantities, or tax rates.

When should I use Inutilização?

Use Inutilização when a range of NF-e numbering has been damaged, lost, or will not be used. This tells the tax authority that those numbers are intentionally skipped.

What is DF-e Distribution?

DF-e Distribution allows you to query all fiscal documents (NF-e, CT-e, etc.) issued against your CNPJ. Use it with the last NSU to retrieve only new documents.

Can I automate my accounting department with this?

Yes! The 'List by Period' and 'Download XML & DANFE' capabilities allow your AI agent to fetch all invoices from a specific month, download the XMLs, and seamlessly integrate them into accounting workflows.

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Put Focus NFe to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

Focus NFe works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put Focus NFe to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Focus NFe, so you can see the experience inside your AI.

It does not authenticate your account with Focus NFe. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.
