You can ask your agent to send money to specific people or parse bank codes for high-volume transfers. **Can I use Stark Bank MCP to create virtual cards?** Yes, you can create corporate cards on the fly. This is great for managing team spending or setting up specific limits for different projects. **How do I secure my credentials with Stark Bank MCP?** The Connector uses ECDSA public and private cryptography. You just need to paste your raw private key into the Vinkius credentials, and the agent handles the rest securely. **Can the agent pull my bank statements?** Yes, the Stark Bank MCP can extract detailed cash flow statements. This allows you to analyze historical spending or check invoice statuses in seconds. **Is Stark Bank MCP good for high-volume payments?** It's built specifically for corporate maneuvers. It can handle arrays of workers and complex payment logic that would be tedious to do manually. **Can I track my Boletos with Stark Bank MCP?** Yes, you can list the accounting progress and status of all your Boletos. This helps you see exactly which payments have been settled. **How do I securely pass the Stark Bank ECDSA Private Key to MCP?** Inside Stark Bank, when you generate your API project, the website will generate a Public/Private Keypair or ask you to provide one. You must grab the **Private Key** (often starting with `-----BEGIN EC PRIVATE KEY-----`) and paste that entire raw multiline text into the `STARK_PRIVATE_KEY` input inside the Connector client perfectly as it is. **Can the bot process Corporate Card requests automatically?** Yes! If you instruct the agent to orchestrate the generation using the tool `stark_create_corporate_card`, the API instantly spins up a valid, active Corporate Virtual Card attached to your Master Balance in real-time. **How does the Stark Bank transfer function differ from basic gateway Pix?** Stark Transfer allows hyper granular outbounds. Instead of just pushing a basic Pix key, the `stark_create_transfer` can route massive payrolls, TED systems tracking `BankCode`, ISPB nodes and branch validation—giving you raw underlying banking protocol access. **Will Stark API throttle the connection if the Agent lists too many historic Boletos?** StarkBank allows huge enterprise-grade API ceilings per second. Pulling hundreds of statements using `stark_list_boletos` naturally respects rate limits easily while functioning inside LLM chat turns.
