- Cancel CC-e — Cancel previously sent Correction Letters
- Inutilize Numbering — Mark damaged or lost NF-e numbering ranges as unused
- Download XML & DANFE — Retrieve authorized NF-e XML documents and DANFE PDFs
- Distribute DF-e — Query available DF-e documents for your CNPJ by NSU
- List by Period — Retrieve all NF-e or NFS-e issued or received within a date range
- Download Event XML — Get XML for specific NF-e events (manifestations, CC-e, etc.)
How it works

Frequently asked questions
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' tools allow your AI agent to fetch all invoices from a specific month, download the XMLs, and seamlessly integrate them into accounting workflows.
How does the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
