How do I setup my Base64 Certificate and API credentials?

Log into your Efí account, go to **API > Applications**. Create an app to get the Client ID and Secret. Then generate a Production Certificate (`.p12`). Instead of uploading the file to Vinkius, use terminal command `base64 -i your_cert.p12` to convert it into a plaintext string, and paste that robust text directly into the MCP configuration.

Can I automatically verify if a customer paid a Pix charge just by chatting with my AI?

Yes! Provide the agent the exact transaction id (`txid`) of the generated Pix. The agent will query the `efi_get_pix_payment` tool and immediately tell you if the status is active, answered, or expired.

Does the integration support transferring money out (Cash-out)?

Yes. Using the `efi_send_pix` action, you can initiate outbound immediate payments requesting the agent to process a value directly to a receiver Pix key.

Can I query a history of paid bank slips (Boletos) at the end of the day or month?

Certainly. The `efi_list_boletos` and `efi_get_statement` tool allows you to perform large queries parsing begin/end dates to return summaries directly in your terminal.
