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.

Focus Admin + Cursor FAQ

Common questions about integrating Focus Admin MCP Server with Cursor.

What is Agent mode and why does it matter for MCP?

Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.

Where does Cursor store MCP configuration?

Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.

Can Cursor use MCP tools in inline edits?

No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.

How do I verify MCP tools are loaded?

Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
